Smaller builds, hackathon weekends, and things that existed to answer one question. Every one of them is still public, including the ones that answered it badly.

    Can a RAG pipeline feel instant if the expensive half happens off the request?

    A chat-with-video workspace. Paste a YouTube URL and it queues a job immediately rather than making you wait — a background worker fetches the transcript, chunks it, embeds it and stores the vectors. Questions get embedded too, matched by similarity search over an HNSW index, and answered against the chunks that actually came back.

    Freelance work: the site for a studio selling design as a subscription rather than as a hire — premium creative on a flat monthly fee. Built in Next.js.

    How do you prove someone starred a repo before a deadline?

    Detects re-stars: people who unstar and re-star a repository to game an event's leaderboard. Takes a baseline snapshot before the event, then compares submitted usernames against it.

    The site this one replaced. React and Tailwind with a vertical timeline down the middle, still up at sumanjain.vercel.app — worth keeping up, because it is the thing the rewrite was arguing with.

    What can actually be finished in seven days?

    A hackathon build, TypeScript end to end, designed and demoed inside a week. The demo video is the artefact — it was never meant to outlive the weekend.

    A landing page for the group I build with. Kept deliberately small and static — the whole point was that it loads instantly and needs no maintenance.
