What I'm looking for

I seek a collaborative, agile team role where I can build performant web apps, lead feature delivery, mentor engineers, and improve CI/CD and observability.

I am a Fullstack Engineer with 5+ years building scalable web applications using React, TypeScript and Node.js, focused on performance, UI/UX, and reliable APIs.

I have implemented end-to-end solutions that improved application speed by 25%, reduced bug-fix times by 70%, and increased operational reporting and delivery efficiency through automation and monitoring.

I mentor junior developers, lead feature rollouts, migrate codebases to TypeScript, and establish CI/CD and observability practices to maintain high quality and uptime.
