Vedansh Chandak

I’m a Full Stack Developer (MERN) with 1+ year of production freelance experience, focused on shipping high-performance web systems. I co-built Sanjeevani, a national award-winning (SIH 2025, 2nd place among 500+ teams) blockchain-powered GovTech platform for the Ministry of Ayush.

In a production MERN eCommerce contract, I delivered sub-200ms APIs by designing and deploying 10+ RESTful services with optimized aggregation pipelines. I also reduced booking processing time by ~40% through JWT auth, real-time booking, and Stripe payments, while improving reliability with Jest + Supertest integration tests (80% coverage on core flows).

I build end-to-end AI features too—like ResumAI, an AI-powered resume builder using a RAG pipeline (ChromaDB + SentenceTransformers) with role-specific, ATS-optimized output and sub-100ms async backend performance. For GovTech, I worked on OCR + IVR onboarding and deployed an aRAGAI chatbot that resolves 80%+ of herb-related queries.

I’m proficient across React/Next.js, Node.js/Express, FastAPI, and MongoDB/PostgreSQL, with a strong emphasis on security (JWT auth, RBAC), testing, and DevOps. I enjoy turning complex requirements into clean APIs, measurable performance wins, and real-world user impact.
