Encouraged to embrace new techniques, tools, and approaches, our people keep growing and developing their skills while exceeding clients’ expectations and staying one step ahead in the industry.

Over the past twelve months, our team has conducted a long-term experiment with GitHub Copilot, a ground-breaking AI tool with the potential to transform the way we develop software.

In this article, we share the insights and experiences of Martins Penkevics, JavaScript Lead Developer, Muntis Rudzitis, Lead Data Scientist, and José Mota, JavaScript Developer – who have been leveraging GitHub Copilot in their daily tasks for more than twelve months. 

What is Copilot?

Copilot is an advanced AI-powered coding assistant developed by GitHub in collaboration with OpenAI. It seamlessly integrates with development environments – in our experience with Microsoft’s Visual Studio Code – providing real-time code suggestions as developers type. By understanding context and intention, Copilot accelerates coding tasks, generates code blocks, and promotes consistent coding standards. It promises to act as a thinking and working partner, transforming the coding experience, and reshaping collaboration between developers and AI tools. But how effective is Copilot, and how does it impact the code structure and the developer’s way of working?

Meeting early expectations and beyond

Our team’s expectations for Copilot differed from one professional to another, but there were some common grounds regarding how they hoped the tool would support their work. We essentially expected Copilot to predict code, complete sentences, and streamline routine coding tasks – especially in syntactically strict languages. Copilot surpassed these expectations by not only automating tasks but also adapting to their workflow and thought processes. The tool predicts thoughts and demonstrates an incredible ability to guess intentions, making it a powerful partner in navigating the complex landscape of code.

Copilot predicting the line of code

For our Lead Data Scientist, Muntis Rudzitis, Copilot evolved throughout the months, revealing two distinct aspects. First, the code completion feature accelerates routine tasks and adapts to the expectations set by historical code completion tools. Compared to traditional code completion, it learns the style of a whole code base, making it easier to keep it consistent when multiple people are working on the same code base. Second, the newly introduced chat interface, very similar to Chat GPT, provides a more conversational and interactive environment – that can help the developer to automate diverse tasks such as organizing documentation, addressing a code block, or debugging it.

Development scenarios

We worked in Scrum teams (5 to 9 people) to benefit from stronger collaboration, communication, adaptability, and focused on deliverables leveraging Copilot to develop and deliver large-scale enterprise solutions for our clients – proving its value and reliability in production environments. In most cases, we integrated Copilot with Microsoft Visual Studio Code and in some instances, with Copilot Chat Extension.

Copilot seamlessly adapted to a range of different development scenarios and technologies – from frontend development with React and our Infinity Design System; to backend development with our team using GraphQL, Node, NoSQL, and Cloud services for the delivering of intricate business logic.

Coding standards and best practices

Copilot demonstrated prime adaptability to coding standards and naming conventions. It improved our coding practices by following project-specific guidelines enforced by linters and IDE settings and following best practices in the absence of predefined standards.

Copilot’s impact on performance

Boosting productivity

One of Copilot’s standout features is its impact on personal productivity. It doesn’t merely suggest code snippets, it actively predicts patterns, making repetitive and tedious coding tasks significantly faster. Thereby streamlining the work and turning many of the less enjoyable aspects of programming into less tedious tasks.

Improving coding style and quality

Besides completing code lines, Copilot also improves coding style and overall quality. Martins Penkevics, our JavaScript Lead Developer, highlights how the tool’s suggestions for naming variables and functions contribute to a more organized and readable codebase.

Enhancing motivation

By swiftly handling the mundane or repetitive coding sections, Copilot reduces the moments of frustration. The elimination of tedious tasks contributes to a more enjoyable work environment, enhancing motivation and, consequently, creativity.

“Copilot significantly improves motivation by limiting the tedious aspects of programming. It takes care of the repetitive and less enjoyable tasks, allowing me to focus on the more interesting and creative aspects of my work.”

José Mota, JavaScript Developer

Enabling conceptual focus

By automating mechanical and template-driven tasks, Copilot offers extra time for developers to dive into higher-level, creative problem-solving – particularly valuable when tackling novel libraries or frameworks.

“It allows me to focus on the conceptual aspects rather than getting deeply involved in the specific, niche details when working with new libraries. This is particularly useful in scenarios like initiating a typical data analysis for a project.”

Code documentation made easy

Copilot automatically generates comments and documentation snippets, streamlining the process of explaining code changes or functions. This feature not only enhances the quality of documentation but also encourages meaningful commenting practices.

“I had to work on a third-party component with tricky documentation. With Copilot, I just wrote a comment about my intentions, and voilà, I had a working code block. It saved me hours of navigating through documentation.”

From Data Analysis to UI development

Copilot assisted Muntis in efficiently organizing and presenting tabular data. Additionally, when faced with creating a dashboard tool for a client, Copilot played a pivotal role in navigating an unfamiliar Python library (Dash), providing structure and guidance.

Teaching and learning buddy

When venturing into new frameworks or libraries, Copilot supports grasping the syntax and nuances of unfamiliar structures, reducing the time spent on trivial details and allowing for a smoother learning curve.

For junior developers, Copilot has the potential to become a powerful mentor, offering suggestions and generating code for unfamiliar tasks. This accelerates the coding process and creates a micro-learning environment that is truly work-based.
