About the Author

Sandor Dargo
Sandor Dargo

I am a C++ software craftsman with strong Python working in the tourism and hospitality industry and an enthusiastic blogger writing about coding, books, and the importance of stoic philosophy in a software developer's life.

I moved to software development from database operations which means that I don't just care about delivering a product as fast as possible, but I do understand the importance of stability and maintainability.

I'm passionate about delivering clean solutions, but I find even more important to help my teams to constantly raise the bar and to (re)focus on quality and clean code. I do this by explaining how high-quality work will help them in their individual careers, by introducing more meaningful development processes and automation and by teaching them industry best practices.
