A jellyfish has no brain.
It has a nerve net — thousands of neurons, none of them in charge.
And yet it moves as one.
It's been doing this for over 500 million years.

I build reliable backends and the products around them — and explore systems by building their core parts.

I wasn't trying to use systems yet.
I was trying to understand why they worked.

I took a standalone reconciliation tool and turned it into a service operations teams could run on their own — retries, account-wise processing, and unmatched transactions carried into the next run.
When the heap ran out, I didn't add memory. I changed the shape of the work — chunked streams instead of everything at once.

LAMF lets investors borrow against their mutual fund units instead of selling them. The people on the other end were high-net-worth customers — every one of them with holdings worth more than ₹5 crore.
I worked on the integrations with CAMS and KFintech — the registrars that keep India's mutual fund records — and on making that path resilient and scalable, so a slow or failing registrar call doesn't break a customer's loan journey.
Watch the two streams: when one drops, a retry pulse runs in and the flow recovers.

Somewhere in a very large sky of databases is personal information. My work is helping find it, label it and govern it — carefully.
Spring Boot services across two data centres, 29+ kinds of data store, versioned policies with 100% scan reproducibility across three MVP releases, and mTLS, SSO and role-based access — because privacy tooling has to be the most trustworthy thing in the room.

A Redis-compatible server, wire-compatible with standard Redis clients: the RESP v2 protocol, strings, lists, sorted sets on a skip list, streams, TTL expiry, pub/sub, master–replica replication and MULTI/EXEC transactions. It began as a CodeCrafters challenge and grew from there.
An interactive Unix-style shell: parsing, pipelines, redirection, history, tab completion — and automated release packaging.
