About

I'm a Full Stack Engineer with a passion for building scalable, production-grade systems. My expertise lies in architecting backend infrastructure that handles real-world complexity — from high-throughput data pipelines to real-time collaboration platforms.

I specialize in:

  • ▸Scalable Backend Architecture — Designing systems that grow with your business
  • ▸Real-Time Systems — WebSocket, Redis Streams, event-driven architectures
  • ▸REST & WebSocket APIs — Clean, documented, production-ready interfaces
  • ▸Production Infrastructure — Docker, Kubernetes, CI/CD, monitoring, and observability

I work primarily with Node.js, TypeScript, Laravel, and React, but I'm language-agnostic and focus on solving problems with the right tools.
