Illustration of two sides in a tug-of-war representing the trade-off between speed and quality in software development

How to Balance Speed and Quality in Software Development?

Speed and quality in software development are not mutually exclusive, but they are often in tension. Many engineering teams face this paradox daily: deliver quickly to meet business demands, while maintaining a robust, scalable, and maintainable codebase.

This article explores how experienced teams approach this trade-off – not through buzzwords, but through deliberate architectural and operational decisions

1. Understand That “Speed” ≠ “Shipping Features Fast”

Speed isn’t just about velocity in terms of story points. Real delivery speed is sustainable only when:

  • Code is testable and predictable
  • Pipelines don’t break randomly
  • Rollback strategies exist
  • Monitoring gives confidence in production

In other words, real speed comes from removing friction in delivery – not skipping steps.

Example: A team that skips writing tests can move fast once. A team that builds stable test suites can move fast every sprint.

2. CI/CD Is Table Stakes—But It’s Not the Goal

Implementing CI/CD is not a solution; it’s a prerequisite. What matters is:

  • How fast and reliable your pipelines are
  • How confident your team is in rolling forward (or back)
  • Whether deployments are observable and reversible

✅ Use blue/green or canary releases
✅ Enforce build reproducibility
✅ Automatically verify infra changes in staging

Tooling tip: GitHub Actions + ArgoCD or GitLab CI + Terraform can automate most of this. But the culture of ownership matters more than the stack.

👉 Know more about: What is CI/CD

3. When to Accept Technical Debt – And When to Fight It

Not all technical debt is bad. Deliberate technical debt is sometimes necessary to meet market windows. The key is to track it, constrain it, and pay it back before it compounds.

  • Use tools like SonarQube to track maintainability scores
  • Tag TODOs with debt type (#intentional-debt, #performance-tradeoff)
  • Bake refactoring into your roadmap (not as “nice to have”)

“We’ll refactor later” is not a plan. “We’ll refactor in Sprint 9 to prepare for multi-region support” is.

4. Quality Comes from Code Reviews, But Only If They’re Real

A review that focuses on indentation is a waste. High-quality teams:

  • Use checklists: security, performance, failure modes
  • Apply pair programming in critical modules (e.g., billing, auth)
  • Enable async reviews, but timebox them (e.g., within 24h)

And yes – skip the review if the change is trivial and the risk is minimal. Make that a documented rule.

5. Optimize for Feedback Cycles, Not Just Feature Cycles

Long feedback loops kill both speed and quality.

  • Test in parallel (not sequential QA → UAT → Prod)
  • Use feature flags to decouple release from deploy
  • Get product validation as early as possible (dogfooding, beta groups)

Short feedback = less rework = more sustainable velocity

Final Thoughts

Balancing speed and quality in software development isn’t a slogan—it’s a continuous series of technical and cultural trade-offs. There’s no one-size-fits-all solution, but the best teams:

Make decisions that optimize for feedback and learning

Embrace automation, but never blindly

Track debt like it’s real

View CI/CD and observability as foundations, not features

WHAT TECH STACK TO CHOOSE FOR YOUR OUTSOURCING PROJECT

If you are considering the development of a web or mobile application for your company, it is important to understand the key tools that developers utilize in such projects. This is because the technology stack employed can significantly impact both the speed of application development and the ability to scale the product in the future. Additionally, it can influence the cost your company incurs for project support and maintenance.

To streamline the process of selecting a suitable technology stack for your web or mobile application in 2022, we have compiled an overview of the most essential tools utilized by popular applications such as Netflix and Airbnb. By referring to this guide, you can save time and effort that would otherwise be spent on searching for the ideal tech stack for your project.

What does a Tech Stack mean?

A Tech Stack refers to the collection of software tools utilized by developers to construct an application, including software applications, frameworks, and programming languages that are responsible for implementing various aspects of the program.

In terms of its composition, the tech stack is comprised of two essential components – the front-end or client-side and the server-side or back-end.

Web applications resemble websites that can be accessed through browsers, allowing users to utilize them without the need for downloading them onto their devices. The technology stack for web applications leverages system resources, necessitating the consideration of a combination of front-end and back-end technologies to develop a web product.

In contrast, developers construct native apps designed for a specific platform or environment, where their code and data cannot be utilized elsewhere. To access these applications, users must download them from the app marketplace.

Therefore, when constructing a native app, it is important to consider the use of platform-oriented technologies and tools, such as Swift and Objective-C for iOS and Java or Kotlin for Android app development.

Let us delve further into the tech stacks required for both web and mobile app development processes.

Tech stack for a web software

The back-end technology stack is responsible for ensuring the smooth operation of the internal workings of an application or website. It is particularly crucial if the site features anything other than simple, static HTML-coded pages. The tools that developers use for the back-end stack include various programming languages such as Python, PHP, and JavaScript, frameworks like Ruby on Rails, Flask, Django, Swift, or Objective-C, databases such as MongoDB and MySQL, and server providers like Apache, Nginx, and others.

In contrast, the front-end technology stack determines the user’s experience when they interact with an application or website. Thus, the primary focus of the front-end stack is to provide an accessible user interface, a convenient user experience, and clear internal structures. The appropriate technology stack for the front-end or client-side of web software consists of HTML, CSS, and JavaScript.

HTML is responsible for organizing and placing data on the page, serving as the backbone of the front-end stack. CSS is responsible for presenting the data, including features such as colors, fonts, background, and layout peculiarities. If interactive features are required, developers can choose JavaScript, which can be controlled via libraries such as jQuery, React.js, or Zepto.js, integrated into frameworks like Ember, Backbone, or Angular.

The tech stack for an iOS application

When developing an application for Apple devices, it is essential to find a team with expertise in Objective-C and Swift, the primary programming languages used in the iOS software development process. Additionally, developers may consider utilizing integrated development environments like JetBrains AppCode and Apple’s Xcode. Let’s examine the iOS technology stack in greater detail.

Objective-C is an established open-source framework that utilizes pointer concepts similar to C and C++ programming tools. It has been widely tested and is reliable, with numerous third-party frameworks available.

Swift, on the other hand, is a newer framework released in 2014 and is commonly used for iOS product development. Swift’s advantages include faster coding, better memory management, code reusability, and simpler debugging when compared to Objective-C. For instance, our team recently used Swift to develop Nioxin, a product for hairstylists. To learn more about this project, please follow the link.

Xcode is a powerful open-source development environment that integrates with the Cocoa and Cocoa Touch frameworks. It includes numerous developer tools for building apps using Objective-C. The Xcode software package comprises a text editor, compiler, and build system, enabling iOS developers to write, compile, debug, and submit their apps directly to the Apple app store.

Another iOS app code editor for Swift, Objective-C, C, and C++ is AppCode. Similar to Xcode, it offers faster coding, improved file navigation, editor customization, and other advantages.

The tech stack for an Android application

Java is an object-oriented programming language that is widely used for Android projects and is particularly popular among prominent companies such as Google and Yahoo. When developing an Android app, developers can use the Android SDK, which provides a plethora of libraries for data structure, graphics, mathematics, and networking to facilitate the creation of their application.

Kotlin is another programming language that has gained widespread popularity among Android app developers. It is commonly used for developing server-side applications, and one of its primary advantages is its ability to reduce the amount of necessary code. This feature is particularly useful in situations such as findViewByIds, one of the most frequently executed operations in Android development.

Android Studio is the official Integrated Development Environment (IDE) for developing Android projects. Android Studio provides developers with a variety of features, including code writing and debugging capabilities, to enhance their productivity and make the development process more efficient.

Important considerations about the technology stack in 2023

Scalability is a crucial aspect of software development, and the tech stack serves as its foundation. Although tweaks can be made according to operating results, the tech stack must have the necessary elements to support scalability.

There are two types of scalability: vertical, which involves adding more elements and data to an application, and horizontal, which involves the ability to run on more devices. Both types are equally important to make a product effective and successful.

Performance plays a critical role in software development and comes from two sources: business requirements and the technology’s capabilities. Operating characteristics and requirements depend on how fast the system can react and how many requests it can process at what rate.

Maintaining strict operating characteristics requirements is vital when choosing the tech stack since the entire operation must react to thousands of events at millisecond speed. Therefore, picking the most reliable option is essential.

Budgeting for the tech stack is one of the most challenging aspects of software creation. It demands significant financial resources, including hosting costs for product data, developers’ salaries, technology education and licensing fees, and subsequent maintenance costs. The trick is to manage to balance things out, avoid bloating, and overspending for the tech stack wherever possible.

Things to consider when hiring an app development company

Various types of applications require different tools and technologies. Web development projects, for example, involve a range of backend and frontend technologies and tools, whereas iOS and Android projects typically use a single coding language.

When seeking development services, it is not always necessary for you or your company to participate in the selection of technologies and tools. However, factors such as agility, operating characteristics, and costs are crucial to the success of your project. Therefore, do not hesitate to ask your developers about the technologies they plan to use to validate your business idea. They will provide you with a clear understanding of the pros and cons of the selected tech solutions.

What Is Fintech? What you need to know about Fintech before it explodes in 2023

Fintech, a combination of the terms “financial” and “technology,” refers to businesses that use technology to enhance or automate financial services and processes. The term encompasses a rapidly growing industry that serves the interests of both consumers and businesses in multiple ways. From mobile banking and insurance to cryptocurrency and investment apps, fintech has a seemingly endless array of applications.

Today, the fintech industry is huge. And if recent venture capital investments in fintech startups — which reached an all-time high in 2021 — can be considered a vote of confidence, the industry will continue to expand for years to come.

One driving factor is that many traditional banks are supporters and adopters of newfangled fintech, actively investing in, acquiring or partnering with fintech startups. Those are ways for established banking institutions to give digitally minded customers what they want, while also moving the industry forward and staying relevant.

How Does Fintech Work?

The inner workings of financial technology products and services vary. Some of the newest advancements utilize machine learning algorithms, blockchain and data science to do everything from process credit risks to run hedge funds. There’s even an entire subset of regulatory technology dubbed regtech, designed to navigate the complex world of compliance and regulatory issues of industries like — you guessed it — fintech.

As fintech has grown, so have concerns regarding cybersecurity in the fintech industry. The massive growth of fintech companies and marketplaces on a global scale has led to increased exposure of vulnerabilities in fintech infrastructure while making it a target for cybercriminal attacks. Luckily, technology continues to evolve to minimize existing fraud risks and mitigate threats that continue to emerge.

Types of Fintech Companies

Mobile Banking

Mobile banking refers to the use of a mobile device to carry out financial transactions. The service is provided by some financial institutions, especially banks. Mobile banking enables clients and users to carry out various transactions, which may vary depending on the institution.

Mobile banking services can be categorized into the following:

1. Account information access

Account information access allows clients to view their account balances and statements by requesting a mini account statement, review transactional and account history, keep track of their term deposits, review and view loan or card statements, access investment statements (equity or mutual funds), and for some institutions, management of insurance policies.

2. Transactions

Transactional services enable clients to transfer funds to accounts at the same institution or other institutions, perform self-account transfers, pay third parties (such as bill payments), and make purchases in collaboration with other applications or prepaid service providers.

3. Investments

Investment management services enable clients to manage their portfolios or get a real-time view of their investment portfolios (term-deposits, etc.)

4. Support services

Support services enable clients to check on the status of their requests for loan or credit facilities, follow up on their card requests, and locate ATMs.

5. Content and news

Content services provide news related to finance and the latest offers by the bank or institution.

Challenges Associated With Mobile Banking

Some of the challenges associated with mobile banking include (but are not limited to):

  • Accessibility based on the type of handset being used
  • Security concerns
  • Reliability and scalability
  • Personalization ability
  • Application distribution
  • Upgrade synchronization abilities

Cryptocurrency Fintech

Of course, one of the biggest examples of fintech in action is cryptocurrency. Cryptocurrency exchanges have grown significantly over the past few years. They connect users to financial markets, allowing them to buy and sell different types of cryptocurrencies. Furthermore, cryptocurrency uses blockchain technology, which has become popular throughout the industry. Because of the security provided by blockchain technology, it can help people reduce fraud. That increases people’s confidence in the financial markets, further expanding cryptocurrency and all companies that use blockchain technology.

Right now, it is difficult to say what the future of fintech and crypto will look like. The only certainty is that it will play a major role in the business world moving forward. Cryptocurrency itself has contributed to the development of numerous new technologies, including blockchain technology and cybersecurity, that will be foundational to financial markets in the future.

Fintech Investment and Savings

One such new trend has been rising interest in savings and investing applications, the type of service fintech startups offer consumers. TechCrunch has covered this trend, noting a number of American fintech and finservices seeing hugely rising user activity and revenue.

Robinhood, the best-known American zero-cost trading app, has seen its trading volume skyrocket along with new user signups. Research into the company’s filings show that its revenue grew to over $90 million in the period as its income from more exotic investments like options advanced.

The trend of growing consumer interest in saving money (reasonable during an economic crisis) and investing (intelligent when equity prices fell off a cliff in March and April) has helped smaller fintech startups as well. Personal finance platform M1 Finance and Public, a rival zero-cost stock trading service, have also seen growing demand. The trend is so pronounced that new stories seem to crop up every few days concerning yet another savings or investing fintech that is blowing up, like this recent piece concerning Current.

 

Machine Learning and Trading

Being able to predict where markets are headed is the Holy Grail of finance. With billions of dollars to be made, it’s no surprise that machine learning has played an increasingly important role in fintech — and in trading specifically. The power of this AI subset in finance lies in its ability to run massive amounts of data through algorithms designed to spot trends and risks, allowing consumers, companies, banks and additional organizations to have a more informed understanding of investment and purchasing risks earlier on in the process.

Payment Fintech

Moving money around is something fintech is very good at. The phrase “I’ll Venmo you” or “I’ll CashApp you” is now a replacement for “I’ll pay you later.” These are, of course, go-to mobile payment platforms. Payment companies have changed the way we all do business. It’s easier than ever to send money digitally anywhere in the world. In addition to Venmo and Cash App, popular payment companies include Zelle, Paypal, Stripe and Square.

Fintech Lending

Fintech is also overhauling credit by streamlining risk assessment, speeding up approval processes and making access easier. Billions of people around the world can now apply for a loan on their mobile devices, and new data points and risk modeling capabilities are expanding credit to underserved populations. Additionally, consumers can request credit reports multiple times a year without dinging their score, making the entire backend of the lending world more transparent for everyone. Within the fintech lending space, some companies worth noting include Tala, Petal and Credit Karma.

Insurtech — Insurance Fintech

While insurtech is quickly becoming its own industry, it still falls under the umbrella of fintech. Insurance is a somewhat slow adopter of technology, and many fintech startups are partnering with traditional insurance companies to help automate processes and expand coverage. From mobile car insurance to wearables for health insurance, the industry is staring down tons of innovation. Some insurtech companies to keep an eye on include Lemonade, Kin and Insurify.
