What I'm looking for

I’m looking to build ownership-driven, production-grade products—shipping scalable TypeScript/Node.js services and modern React/Angular frontends. I want a team focused on microservices, event-driven systems, AWS reliability, and measurable performance improvements.

I’m a Senior Full Stack Engineer with 6+ years of experience designing and shipping production-grade applications across fintech, healthcare, gaming, and marketplace platforms. I work end-to-end—architecting TypeScript/JavaScript backends in Node.js with Express and NestJS, building responsive frontends in React and Angular, and connecting it all through well-structured REST and GraphQL APIs.

I take ownership from the first database schema to the last CloudWatch alarm, with a strong focus on microservices, event-driven systems, and horizontal scalability on AWS. I’ve led backend transformations like replacing a Node.js monolith with horizontally scaled NestJS services on AWS ECS (sustaining 5× peak load), reduced settlement time from ~8s to under 2s, and improved incident detection from ~45 minutes to under 10 minutes—while guiding teams to keep release deadlines on track.
