Production-grade Software Developer focused in Clean Architecture, TDD, and modern engineering standards. Expert in delivering end-to-end systems—from requirements to deployment—with a relentless focus on maintainability, security, and automated quality control.
I leverage AI as an intelligent pair-programming collaborator while maintaining full sovereignty over architectural decisions and business logic. My approach combines cutting-edge AI assistance with rigorous fundamentals: AI suggests; I decide, validate, and lead.
