01 — About

Engineer across the entire stack.

I’m a software engineer who refuses to stay in one lane — I ship AI agents, mobile clients, slick frontends and the backends that power them, end to end.

Today at Fig AI I architect Stella — one LangGraph + FastAPI + Claude plan-and-perform loop that builds websites, generates media, researches the web and acts on your connected apps, fanning out to recursive subagents when work can run in parallel — and the gateway that streams it to mobile, web, desktop and chat over a resumable SSE block protocol, with MCP servers, a memory layer and human-in-the-loop consent gating behind it.

Before that I engineered banking-grade mobile experiences at Kotak 811 and Groww — custom native bridges, high-performance lists, vision-camera scanners and UPI flows trusted by millions of users under strict regulatory constraints.

I care about the seam where craft meets performance: 60fps interactions, clean architecture, reusable SDKs, and AI that actually ships to production.

Away from the keyboard, I’ve been a drummer for over 12 years — the timing and feel carry straight back into how I build — and you’ll usually find me out on a long drive, which is where most of my best ideas show up.

Production · Fig AI
🤖/ 01

Stella — Agentic AI Platform

The single AI orchestrator behind Fig's one-chat-box product. A LangGraph plan-and-perform loop on FastAPI + Claude drives every turn — building and deploying websites, generating image/video/music/slide media, researching the web and acting on the user's connected apps, all in one graph instead of a separate planner and executor. Parallelizable work fans out to recursive subagents: the same graph re-run with a narrowed toolset and a specialized prompt, so deep research can hit ~15 sources at once with no separate worker service. Turns stream over a resumable SSE block protocol backed by Redis event streams and PostgreSQL checkpointers, and a modular skills framework plus MCP servers load capabilities on demand.

Business Software Suite

An end-to-end suite that runs a real business top to bottom — a marketing website, a billing & invoicing / POS app with PDF receipts and QR payments, and an analytics admin dashboard with live charts and Excel/PDF exports. One shared design system, auth and Firebase data layer across all three apps.

Offline AI on Mac & iPhone

An AI assistant that runs entirely on your Mac or iPhone. No internet, no API bill, and nothing you type ever leaves the device — which matters most for the personal writing people paste into chatbots without thinking. A Swift SDK runs llama.cpp in-process, picks a model that fits the hardware it finds, and calls the cloud only when a request is genuinely too slow or too battery-expensive to answer locally. Built measurement-first: a benchmark harness produced 52 documented findings across three real devices, including the ones that disproved my own earlier conclusions.

Where I’ve shipped.

Nov 2025 — Present San Francisco, USA · RemoteCurrent

Fig AIFull Stack AI Engineer

Architected Stella, the single AI orchestrator behind Fig's one-chat-box product — a LangGraph plan-and-perform loop on FastAPI + Claude that builds and deploys websites, generates image/video/music/slide media, researches the web and acts on the user's connected apps, all in one graph rather than a separate planner and executor. Parallelizable work is delegated to recursive subagents — the same graph re-run with a narrowed toolset and a specialized prompt — for orchestrator-worker fan-out such as deep research across ~15 sources at once. Built agent-gateway, the client edge for a React Native mobile app, a Next.js + Vite web app, an Electron desktop app and messaging channels (Telegram, SMS): Firebase auth, server-side turn lifecycle, conversation persistence and a resumable SSE turn contract (POST /turn → 202, GET /stream with Last-Event-ID) whose block.start / delta / end protocol renders text, thinking, tool and plan blocks as server-driven UI cards over Redis turn-event streams and PostgreSQL LangGraph checkpointers. Extended the platform with a modular skills framework and MCP servers for on-demand capability loading, a persistent memory and knowledge layer, Composio connectors (Gmail / Slack / Notion / Calendar), sandboxed code execution and scheduled tasks on E2B, and human-in-the-loop consent gating on high-impact actions — with model tiering (Sonnet for reasoning, Haiku / Gemini Flash for classification) and prompt caching holding down cost and latency. Led a full UI/UX revamp of the mobile app and shipped Stripe checkout, subscriptions and an in-app wallet.
