Message

At BePro, I architected a scalable platform supporting 20+ enterprise B2B clients and 1,000+ daily active users, with 99.9% uptime. I also developed travel APIs handling millions of requests monthly.

I optimized delivery and backend services using Python, FastAPI, Node.js, PostgreSQL, Docker, and CI/CD pipelines, with a focus on reliability and low latency.

Previously, at Autoretech, I developed web and mobile marketplace platforms and created 30+ AngularJS components, reducing front-end bundle size by 20%. At StartupSoft, I developed backend services and caching strategies for a social networking platform supporting 1,000+ concurrent users.
