Software developer who is enthusiastic about technology: how things work, why they break, and how to fix them properly.
In my spare time I look for real bugs in open-source tools, reproduce them, and send the fix upstream. It is the best way I have found to keep learning, because every project has a different language, a different test setup and maintainers with their own standards.
36 pull requests merged across 17 projects · updated 31 October 2026
Bug fixes in projects I had not worked on before. Each one was reproduced before it was fixed and checked against the project's own tests.
