Summary

I'm a specialist in React, Node.js, and related technologies. My skills overlap greatly with AWS/DevOps, and I often function as a code owner/mid‑senior engineer, making sure projects work end‑to‑end. I prioritize clear communication, writing clean, high‑performing, secure, and bug‑free code, and ensuring the project is finished correctly and on time.
