I’m a Computer Science graduate specializing in backend systems and full-stack development, with a strong focus on building scalable REST APIs and optimizing database performance. I enjoy using Data Structures and Algorithms to solve complex problems and improve system reliability.

Through open-source contributions, I’ve shipped and strengthened real features across multiple repositories—engineering frontend layouts, fixing critical bugs, and optimizing performance across 20+ merged pull requests to improve codebase loading speeds by 25%. I also refactored backend integrations to boost AI recommendation pipeline reliability (reducing request failures by 15%) and optimized database query routines to improve API response times by 10%, collaborating with 15+ maintainers using Git workflows and code reviews.

In my projects, I built a React/Node fitness & diet planner using the Gemini API and added asynchronous PDF generation to reduce report rendering latency by 30%, while streamlining recommendation workflows by 50%. I also developed a Smart Food Rescue system with role-based JWT security, real-time coordination via Socket.IO, and map-based routing (improving routing efficiency by 20% and reducing communication delays by 35%).
