πŸ‘€ About me

Hi, I'm a Senior Backend Engineer with 7+ years building scalable, high-load web applications and distributed backend systems across fintech and AI. I've architected microservices platforms handling 2,000+ concurrent processes at 500+ RPS, optimized storage for 100M+ records, and built secure financial applications serving 6M+ users. I work primarily with Node.js, NestJS, TypeScript, PostgreSQL, Docker, and Kubernetes, and enjoy system architecture, technical decision-making, and mentoring.
