About Me
I'm a Software Engineer with a dual degree in Electrical Engineering from IIT Kharagpur. I thrive at the intersection of clean code and thoughtful product design.
At Pulse Energy, I build full-stack features for EV charging infrastructure — from responsive React UIs to performant Node.js APIs with Prisma. My work ships in the MG Motor app, used by thousands of EV owners daily.
Beyond my job, I build side projects, explore new technologies, and love the challenge of turning complex problems into simple, elegant solutions.
Products
India-first anime/otaku-themed men's clothing e-commerce platform. Full monorepo with a Next.js storefront and Express + TypeScript API. Features Razorpay payments (UPI, cards, COD), phone OTP + JWT auth, Cloudinary CDN images, Prisma ORM with 15+ models, and CI/CD via GitHub Actions.
An MCP server that gives Claude Code, Cursor and Claude Desktop hybrid semantic search over any repository. Tree-sitter AST chunking, local ONNX embeddings (no API key) and BM25 fused with reciprocal-rank fusion. Measured on 50 hand-verified questions: Recall@5 80% → 88%, Recall@1 44% → 62% over a naive RAG baseline. Ships with a remote MCP endpoint, a live retrieval playground and cited LLM answers.
A customer-support AI agent with a hand-written agent loop. It is an MCP client that discovers its tools from three MCP servers (RAG knowledge base, orders, refunds and tickets), and business rules are enforced in the servers rather than the prompt. Measured on 28 scripted scenarios: 27/28 resolved with 0 policy violations, versus 4 of 14 attacks succeeding when the same rules lived only in the prompt.
A full-stack SaaS app that helps Indian employees recover unpaid Full & Final settlement dues from former employers. Features a 4-stage email escalation system (polite reminder → legal notice), formal labour complaint filing with state-specific guides for all 36 states/UTs, Razorpay payments, Google OAuth, and cloud file uploads for evidence management.
A mobile-first PWA for guided timed workout sessions. Upload a PDF or DOCX and AI auto-extracts your weekly schedule. Features a live session timer with sounds, TTS voice instructions, Web Push notifications, streak tracking, and offline support.
A full-featured blogging platform inspired by Medium. Includes search and filter by author, title, date and topic. Users can create, edit, save, and delete posts seamlessly.
A dynamic movie discovery website showing IMDB ratings and descriptions. Features include search functionality, detailed movie pages, and a likes system for personalized experience.
