About Me

Backend-Focused MERN Stack Developer Crafting Scalable Systems

I'm a B.Tech CSE student at Malla Reddy College of Engineering and a backend-focused MERN Stack developer passionate about building scalable backend systems, production-ready APIs, and AI-powered products.

I learn by building real-world projects — from resume optimization platforms leveraging Gemini AI to freelance marketplaces with secure authentication and full-stack e-commerce systems. I'm deeply interested in system design, queue-based architectures, and creating reliable software deployed to production.

My focus is on backend engineering with Node.js, Express, MongoDB, PostgreSQL, and Redis — complemented by frontend skills in React to deliver complete, production-ready solutions.

  • Socket.io for real-time progress updates
Challenges Solved
  • Large resume parsing workflows — solved with background job queues
  • AI processing delays — solved with BullMQ task management
  • Real-time progress feedback — solved with Socket.io WebSocket communication
  • ATS scoring logic — implemented comprehensive scoring algorithm
What I Learned
  • Queue-based architecture for scalable background processing
  • Real-time communication patterns with WebSockets
  • AI integration best practices with Gemini API
  • Scalable API design for SaaS applications
