Deepanshu builds the whole path an AI feature takes: the retrieval layer, the API around it, and the interface people click. TypeScript and Node.js sit underneath nearly everything on file, and p99 latency gets more attention than framework choices.
At Prodigal AI the subject owned the API gateway several internal services routed through, then rebuilt document search on Qdrant and Gemini so teams could stop reading PDFs by hand. The current obsession: making a RAG system behave the same on a Tuesday afternoon as it did in the demo.

Openline
A voice AI receptionist for clinics that answers every call in the browser, no hold music.
What I built
- Suzi books, moves and cancels visits, answers insurance questions and sends refills.
- Warm-transfers the caller to staff on a live console when a clinician is needed.
- Eligibility and refill rules are plain code, not LLM output, and the model only sees slot handles so it can’t invent times.

Inkling
Describe an app in plain words and watch an AI agent build it, with a live preview of real Next.js code.
What I built
- An agent loop writes files and runs commands inside a Daytona cloud sandbox.
- Every step streams to the browser over SSE; a worker persists it from a Redis stream to Postgres.
- Checks that every page loads and fixes its own errors before it hands back.

A perpetual futures exchange for BTC, ETH and SOL, built from the matching engine up.
What I built
- In-memory matching engine with price-time priority, liquidations, ADL and 8-hour funding.
- API, WebSocket server, market maker and Postgres writer all talk to the engine over Redis Streams.
- Engine snapshots every 3 seconds and replays the stream after a restart.

Arpo Bot
A RAG assistant for Bharat Scouts & Guides that answers only from official PDFs, and refuses rather than guesses.
What I built
- Ingests official BSG PDFs with semantic chunking and embeddings in Qdrant.
- Re-ranks context at query time and answers through Gemini and LangChain.
- Says so when the documents don’t cover a question, instead of guessing.

Wisper
Offline dictation for macOS. Hold fn, speak, and your words land in whatever app you are in.
What I built
- Hold fn, speak, and the text lands in whatever app has focus.
- Transcription runs on the Mac with Whisper.cpp, so it works offline.
- Packaged as an Electron app with ONNX Runtime.

Rescho
A room where two people swipe restaurants together and match the moment they both like the same place.
What I built
- Two people share one room; every swipe syncs live over Socket.io.
- A match fires the moment both of them like the same restaurant.
- Next.js front end over a Node.js and MongoDB backend.

I'm open to full-time roles and a small amount of freelance work. The problems I'm best at: an API that has outgrown the shape it was born in, or an LLM feature that demos beautifully and falls apart under real traffic. Tell me what's breaking.
