Über Louis

Senior Backend Engineer specializing in Golang with over 8 years of experience in developing REST APIs and microservices.
I contributed to transforming numerous legacy codebases (mainly PHP) into more stable, high-performing, and maintainable Go services.

I consistently integrate unit and integration tests into CI/CD pipelines, with optimized coverage, to ensure reliable, maintainable, and production-safe code.

I also ensure that the code is properly logged and undergoes rigorous quality control.
