Message

I’m a Backend Engineer with 4+ years of professional experience building scalable cloud-based communications and high-throughput data pipelines. I focus on distributed systems architecture using Node.js (NestJS/Fastify) and Golang, bringing hands-on system design across event-driven design, real-time WebSockets, and stateful caching layers.

I’ve led backend engineering for high-traffic applications and mentored engineers through technical code reviews and sprint execution. I also deliver reliable integrations across Stripe, Twilio, and LLM APIs—while driving measurable performance wins, including a 30% reduction in API response times and lower memory overhead under peak loads.
