Software Engineer @ Emoha · Gurgaon, India

I build systems
that AI agents
can trust.

Rust, async backends and the Model Context Protocol. I write the plumbing that lets LLMs drive real software safely — desktops, Telegram groups, care operations — and I test it until it's boring.

Selected work

Things I built because I wanted them to exist. Most are Rust. All of them run.

● Live

Is the internet dead yet?

A multiplayer canvas where humans fight AI slop, pixel by pixel.

One Rust binary (axum + tokio), all state in memory, a binary WebSocket protocol. Gray static spreads on its own and ships a stronger "model" every 10 min. Share cards are re-rendered from the live board every 30 s; dead internets get a tombstone and a replay.

Harbour

A private, native AI meeting assistant for macOS.

A Swift/AppKit overlay on a Rust core bridged with UniFFI. Two-track audio (the meeting and your mic) transcribed on-device with speaker attribution, streaming answers and notes, conversation memory, five LLM providers behind a local-first privacy gate, and signed offline licenses with a lease server.

Telegram · MCP

Namibot

A group-moderation bot an AI agent can run — without being turned against you.

Rust (teloxide + rmcp). Captcha, flood control, link filters, mod log — exposed as MCP tools over streamable HTTP. Raw Bot API access is fenced: methods that could hijack updates or promote an attacker are blocked, because a prompt-injected agent will try.

Quant research

money-metters

A trading system whose first job is to prove itself wrong.

Real market data, backtests with honest fees and slippage, train/test sweeps that expose overfitting, then paper trading. Live trading stays locked until a strategy earns it. Result: 5.5 years of data showed 1h strategies lose to fees — so they don't ship.

Watchdogs for hostile OEMs

Keeping wireless ADB and Tailscale alive on phones that kill everything.

Two open-source Kotlin apps: an AccessibilityService + WRITE_SECURE_SETTINGS watchdog for wireless ADB, and a foreground service that reconnects Tailscale on Realme/ColorOS, MIUI, Oppo and Vivo.

VegeManagement

Running a vegetable market from a phone.

Flutter app on a Rust REST API (Actix Web, SQLx, MySQL). JWT auth with Argon2 hashing, input validation, PDF reports and dashboard analytics.
