I build the machinery behind the magic.
01 / Selected work
A few things I’ve worked on.
Click a row if you want the longer version.
01 faff Founding engineer · Sep 2025—Mar 2026 Seven months of building everything. No, seriously. <200 ms down from ~2 minutes
Faff was a personal concierge on WhatsApp. I worked on most of it: agents, payments, internal tools, payouts, infrastructure and a fair amount of debugging.
- Shipped production consumer-facing AI agents
- Rebuilt unacknowledged message detection and cut latency from roughly two minutes to under 200 milliseconds.
- Built the internal system used to reconcile thousands of weekly vendor payouts.
- Moved payments from Razorpay to Cashfree and set up multilingual voice outreach.
02 NatWest Group Engineering intern · Jun—Aug 2026 Agent discovery and retrieval for Synapse. Postgres + hybrid search for retrieval
Synapse routes a user’s request to the right workflow or specialist agent. I worked on the search and registry pieces behind that routing.
- Moved search from an in-memory vector store to PostgreSQL and pgvector.
- Added full-text search and BM25 ranking instead of relying only on embeddings.
- Connected Synapse to AWS Agent Registry and worked on the internal capability registry.
03 Together Fund AI engineer · Apr—Jun 2026 Making 2,000+ contacts actually useful. 2,000+ profiles brought together
The fund had useful information spread across spreadsheets, LinkedIn, GitHub and personal sites. I built the pipeline that pulled it together, cleaned it up and found relationships between people.
- Ingested and enriched profiles from LinkedIn, GitHub and personal websites.
- Improved profile completeness by roughly 40–60%.
- Built a graph that could find the shortest introduction path between people.
02 / Writing
I write sometimes.
Usually about technology, startups, politics and India.
Distill to your fill!
I accidentally ended up inside a shadow data-labelling operation. This is what I found.

Things I built for myself.
Some were useful. Some just seemed fun to make.
