Over deze freelancer

Senior full-stack engineer with over 5 years of experience working on real-world production systems used daily by non-technical teams. My strength is stepping into existing React / Node.js (TypeScript) / MongoDB applications running on AWS and improving their stability, performance, and operational safety — without large rewrites or unnecessary risk. I work comfortably across frontend, backend, database, and infrastructure, with a strong focus on ownership and reliability.
