About
React/Next.js Frontend Engineer · DevOps
I build React/Next.js products end to end — from backend API integration through CI/CD, test automation, and security review. Most of my recent work has been on data-intensive platforms in biotech: 3D molecular visualization, scientific charting, and the bundle-size and delivery-pipeline discipline that keeps those products fast to load and safe to ship. I also use Claude Code and Codex to automate parts of testing, review, and refactoring in day-to-day development.
