What I'm looking for

I’m looking to build and scale high-throughput, production systems—owning backend and frontend delivery, hardening reliability and CI/CD, and leveraging distributed systems, caching, and cloud automation to ship confidently.

I’m a Senior Full-Stack Engineer with 7+ years scaling production-grade distributed systems using TypeScript, Node.js, React, and cloud infrastructure. I focus on high-throughput performance, reliability, and clean architecture—turning complex workflows into systems that run fast and stay correct under load.

Recently, I spearheaded a booking engine from zero to production (~26,000 LOC, NestJS/TypeScript), delivering multi-tenant reservation performance at sub-300ms p95 latency for 4,200+ concurrent sessions. I unified multiple external APIs into a single transactional workflow, eliminated recurring payment bugs (~$12K/month leakage), and removed booking race conditions using Redis locking plus PostgreSQL versioning.

I also build for operational excellence: multi-layer caching (Redis, materialized views, CDN), robust CI/CD with SAST/DAST and canary Kubernetes deploys, and infrastructure automation with Terraform and Docker/Kubernetes. I integrate AI-assisted tooling (Claude Code, Cursor, GitHub Copilot) into daily engineering workflows to move faster without compromising quality.
