Welcome to the second part of ‘Behind the scenes of coding’, the column that gives a voice to Bitrockers. After exploring complex data architectures and real-time systems, today we focus on a fundamental aspect of IT consulting: growth and methodological approach.
Our second Ambassador is Fabio Castello, Software Engineer at Bitrock. Fabio represents a new generation of developers who combine a solid logical foundation with a deep curiosity about the evolution of development tools. Through his experience, we will see how even a seemingly simple problem can be transformed into an opportunity for collaboration and structural innovation.
What is the biggest technical challenge you have faced and how did you overcome it?
For me, the most complex challenges are not algorithms — which I consider stimulating exercises in logic — but structural integration problems. I remember a seemingly simple task: modifying an existing API so that it returned data in CSV format as well as JSON.
The real challenge was the request to convert downstream, intercepting and modifying the object that was returned to the caller, and using the same logic for that and other similar APIs. I had to do a lot of research to be able to correctly intercept the response in the framework flow. Thanks to the collaboration with an experienced colleague, we managed to map the data with a dedicated mapper and find an efficient solution. It was a perfect example of how collective effort overcomes technical obstacles.
Which project have you been particularly proud of?
I am currently working on an appointment management and booking system that is giving me great satisfaction. My pride derives from two factors: positive customer feedback and the intrinsic quality of the work.
Comparing my module with other components, I saw neat, efficient and well-tested code. Seeing that clean code translates directly into greater reliability and maintainability is what makes me most proud. It’s not just about writing something that works, but writing something that works well over time.
Which language has surprised you the most?
More than a single technology, I am surprised by the incredible evolution of tools. My father, also a developer, had to debug by reading machine language and studying endless logs. Today, we have advanced debugging tools and IDEs that have become indispensable toolboxes.
Tasks that previously required hours of manual work and line-by-line revisions are now handled automatically by development environments. This evolution of frameworks and libraries allows us to focus on solving the problem, leaving the machine to report formal errors.
Conclusion
Fabio’s interview reminds us that software engineering is a continuous learning process, where methodological rigour meets a passion for logic. At Bitrock, we cultivate this enthusiasm to ensure that our customers always have solutions that meet modern challenges.
