About
Backend Engineer & Full-Stack Developer
I'm a Backend Engineer with 3+ years of experience building scalable web applications. I specialize in Node.js, NestJS, TypeScript, and cloud infrastructure with AWS.
I've architected backend systems serving 50K+ users with 2K+ concurrent WebSocket connections, and delivered 40-65% performance improvements through caching strategies and query optimization.
My experience spans early-stage startups where I've built platforms from scratch, integrated third-party APIs, implemented payment systems, and designed microservices architectures with background job processing.
I'm passionate about clean architecture, performance optimization, and building systems that scale.
