About

I’m a Software Engineer with strong experience in building scalable, secure, and high-performance applications. My core strength is backend development using Node.js, Express, TypeScript, PostgreSQL, and MongoDB, but I also work across full-stack and cloud environments when needed. At KIBI Sports, I own major parts of the backend for a multi-module SaaS platform serving thousands of users. I’ve built multi-role authentication, event and workflow engines, revenue logic, and production-ready APIs deployed on cloud infrastructure. Before this, I worked on two production apps at Virtual Cybertrons, including a car rental marketplace and a speech-to-text platform. What I work on --- Building scalable APIs and backend services Authentication & authorization (JWT, RBAC) SQL/NoSQL database design, modeling & performance tuning AWS deployments, CI/CD pipelines (GitHub Actions), Docker Debugging, performance optimization & system reliability Working in fast-paced product environments Collaborating across front-end, design, and product teams I enjoy taking ownership, shipping features quickly, and solving real product problems. I’m always learning, improving, and building systems that create real impact.
