About
I’m a software engineer and full-stack developer with internship experience building ERP modules and event booking systems using PHP, MySQL, React, Node/Express, and MongoDB. I enjoy turning requirements into clean, reliable features—optimizing SQL queries, adding caching for performance, and implementing secure role-based access control (RBAC) and rate limiting for API endpoints.
I also work on AI and data-driven projects: I’ve built an end-to-end RAG document Q&A application using Python and FastAPI with semantic chunking and vector search (ChromaDB), and I integrated Groq LLMs to produce accurate answers from retrieved context. I’m comfortable across the stack, from UI (HTML/CSS/JavaScript, React) and back-end services to databases and deployment-oriented tooling.

Work experience
Developed ERP modules using PHP and MySQL. Optimized SQL queries to speed up invoice generation by ~40%. Contributed to front-end pages and API integration using HTML/CSS and JavaScript. Worked on an event booking full-stack platform with high concurrency and race-condition safety using Node.js, Express, React, and MongoDB. Implemented JWT-based RBAC and rate limiting middleware, and used atomic MongoDB transactions to prevent overbooking during simultaneous checkouts. Added Redis caching for high-frequency event metadata queries and integrated Razorpay payment APIs for secure booking confirmations and transaction logging.
