Software engineer, technical leader and software architect with 20+ years of experience in software development.

Passionate about coding, coaching other engineers (from all levels) as a tech lead and about creating and improving highly distributed systems with complex and robust architectures. I gravitate much more towards quality than speed, but can be pragmatic when needed; I'm a hard adopter of TDD (Test-Driven Development) and good engineering practices in general. Here's more about how I work as a software engineer:
