01. About Me
I am a Senior Software Engineer with a decade of experience, including 4+ years building mission-critical applications for Volkswagen Group and 2+ years architecting SDKs and distributed systems.
My expertise lies in Frontend Architecture (React, TypeScript), E2E Testing Strategies, and highly scalable Node.js backends. I have a proven track record of delivering enterprise-grade solutions with a rigorous focus on Test-Driven Development (TDD) and Extreme Programming (XP).
Currently, I am exploring AI-assisted development workflows and building security analyzers for Web3 ecosystems. My approach marries enterprise reliability with cutting-edge technological exploration.
