What I'm looking for

I want to build scalable, high-traffic web products end to end—owning architecture, performance, and delivery. I thrive in teams that value code quality, mentorship, and fast iteration with reliable CI/CD and zero-downtime releases.

I’m a full-stack engineer with 7+ years building high-traffic web platforms across fintech, SaaS, e-commerce, and Web3. I architect scalable Node.js backends for thousands of concurrent users, pair them with polished React/Next.js frontends, and take ownership from database design through CI/CD pipeline delivery.

Most recently, at RemoteCo, I’ve architected and scaled Node.js/NestJS microservices for a global hiring marketplace (50K+ registered users), improved React/Next.js performance by ~40%, and reduced API response times from 320ms to under 90ms. I also lead engineering quality—driving code reviews, introducing PR standards and automated linting, and mentoring junior developers—while owning zero-downtime daily deployments with Docker and GitHub Actions.
