I turn complex products into interfaces people actually enjoy using. + years at startups where you ship the whole stack — from drag-and-drop email editors to TypeScript SDKs to AI pentesting tools.
Interfaces by day.
Automations by night.
I've been writing production React and TypeScript since 2021, mostly at early-stage companies where you own the whole thing — not just your Jira ticket.
Outside work, I run local LLMs on my own hardware, maintain a fully offline voice assistant, and built an algo trading terminal for Indian markets — because letting code make (or lose) money is more interesting than watching charts.
I care about interfaces that make complex things feel obvious and code that future-me won't dread maintaining.
