I build fast, reliable, and beautiful web products from pixel‑perfect interfaces to scalable, production‑ready backends.

🚀 About Me

Full‑stack product engineer with 5+ years delivering production web applications end‑to‑end
Strong on both sides of the stack: modern React/Next.js frontends and Node.js/NestJS backends
Care about quality: clean architecture, type‑safety, automated testing, and observability
Business‑driven: focus on measurable impact (performance, reliability, conversion, team velocity)
Currently: building with TypeScript, React/Next.js, Node.js/NestJS, PostgreSQL, and cloud‑native tooling

End‑to‑end ownership: from idea and technical design to implementation, rollout, and monitoring
Robust architecture: layered, testable code with clear boundaries and maintainable abstractions
Real performance gains: profiling, caching, and modern rendering strategies to keep apps fast
Engineering excellence: type‑safe code (TypeScript), automated tests, and CI/CD as standard
Great collaboration: clear communication, documentation, and constructive code reviews

Delivered production full‑stack web apps using React/Next.js, Node.js/NestJS, and PostgreSQL for 10k+ active users
Improved core page load time by 45% and reduced bundle size by 30% through code‑splitting, caching, and performance profiling
Designed and shipped REST & GraphQL APIs that power 60+ endpoints with authentication/authorization and clear domain models
Set up CI/CD pipelines (tests, linting, preview deployments) that cut release time from 2 hours → 10 minutes
Collaborated with cross‑functional teams to launch 12+ major features/year, owning requirements, implementation, and post‑launch improvements
