Full-stack across the entire stack — NestJS · Node.js · Postgres · React

Hi there! 👋 I build full-stack
products that scale

Full-Stack Engineer with 7+ years building production-grade web applications across the entire stack — from REST API design and NestJS/Node.js backends to scalable React/Next.js frontends. I own API contracts and integration logic alongside frontend architecture: microfrontend systems, 35% load-time improvement, and test coverage scaled from 15% to 75%. Experienced in system architecture, cross-functional collaboration with backend teams, and mentoring developers.
