A booking platform for a hostel owner I met while staying there during college — my first large solo build. 250+ bookings and INR 263,000+ in revenue so far, and invoices and agreements are generated automatically, cutting the owner's manual work by about 60%. The lesson I actually took away was about requirements: scope kept moving with the client's mood until I stopped and froze it, sketched the UI on paper, then designed the database.

The hard part was payments. The gateway allowed only one linked account, which didn't fit how the owner took money. So I designed around it: a guest books and immediately gets a slip marked "verification pending", the owner gets an email, confirms once the payment lands, and the booking status updates.

A senior of mine started this mentor–mentee platform and I joined a few weeks in, during my fifth semester. I built the mentor registration page and Google login, then took over more of the core engineering — starting with the Razorpay payment gateway — as he moved to the business side. We onboarded 50+ mentors and 20+ mentees, and the community page still has 7,000+ followers on LinkedIn.

It was picked for GirlScript Summer of Code, which brought in a wave of first-time contributors. I spent much of that time reviewing their PRs and walking them through small mistakes — the same patience Zulip's maintainers had shown me. The project is shut down now; Topmate took that market.

A no-code platform for building AI assistants: upload a knowledge base, tune the retrieval pipeline, test it live, then paste one <script> tag into your site. I designed the LLM orchestration layer and the backend, and built the dashboard around it — 22 routes covering auth, onboarding, a multi-source knowledge base, analytics, a WebSocket playground, and a theming studio.

The part I'd defend in a review is the state boundary. Server state lives in TanStack Query with explicit invalidation; client-only state lives in a persisted Zustand store. Neither leaks into the other, so no component ever calls Axios directly — one hook per resource owns its query keys.

The whole RAG pipeline is configurable from the UI at runtime: chunk size, overlap, splitter, PDF parser, embedding model, temperature, and the system prompt.

A way to play computer games with your body instead of a keyboard. MoveNet reads your pose from the webcam and maps it to game input — raise your left hand, the character turns left — so time at the machine costs you some movement instead of none. Pose detection in TensorFlow and OpenCV, input synthesis with PyAutoGUI, Next.js front end.

An end-to-end pipeline rather than a demo: collected and labelled a 1,000-sample voice dataset, trained and evaluated a speech-command classifier, then deployed it to an Arduino for real-time inference — switching lights on a spoken command.
