Backend Developer - API Development & Testing

Buenos Aires, Argentina·2+ years·Spanish / English

Bio

I write APIs with comprehensive test coverage. 2 years building REST services with a test-first mindset. I believe untested code is broken code. Systems engineering student, learned TDD from online courses and it changed how I code. My PRs include tests, my APIs return proper status codes, and I document endpoints as I build them. Junior but very disciplined in my approach.
