Summary

Full-stack engineer who took Treato, a healthcare platform in India, 0 to 1, from an empty repository to production: two React Native apps live in the app stores, a Go and PostgreSQL backend, a Rust auth service, a Tauri desktop app and Maya, an LLM tool-calling agent, with about 3,500 commits since March 2025. Owned features end to end, from system design to mobile UI, deployment and on-call.

Experience

Full-Stack Engineer (AI), TreatoOct 2024 - Nov 2026 | Remote, India

Healthcare platform connecting patients, families, doctors and clinics around one shared health record.

AI agent: Built Maya, an LLM tool-calling agent in Go that explains prescriptions and lab reports, sets medicine reminders and gives doctors a daily brief. Guardrails: red-flag checks before the model; patient names are swapped for labels before the model sees them; clinical output stays a draft until a doctor approves it.
Mobile apps: Shipped Treato Doc (doctors) and Treato Health (patients) in React Native, Expo and TypeScript: booking, family health records, real-time chat (Elixir, Phoenix Channels, WebSockets) and video visits on self-hosted LiveKit (WebRTC). Treato Doc (version 2.0.9) is live on the App Store and Google Play.
Backend and APIs: Designed the architecture and core REST API in Go (Fiber) on PostgreSQL (~360 migrations), GraphQL reads, RabbitMQ between microservices, Elasticsearch and a Dragonfly (Redis) cache.
Authentication and security: Built Treato ID, an identity provider in Rust (Axum): phone OTP, passkeys (WebAuthn), MFA (TOTP), OAuth 2.0 / OpenID Connect and SSO (SAML), one identity for patients, doctors and clinics (RBAC).
Desktop and web: Tauri desktop app for clinic front desks (queue, walk-ins, billing) with signed builds and auto-update; Next.js website with a public doctor directory.
DevOps and infrastructure: Ran production on a Linux VPS with Docker, Dokploy and Cloudflare R2; a push to main went live in about a minute. About 8,000 automated tests (Jest, Go, Playwright), CI/CD with GitHub Actions, PostHog analytics, Sentry crash reporting, backups and on-call.

Advisor, [24]7.aiApr 2025 - Sep 2025 | Bengaluru, India

Projects

hippo (Rust, open source): memory for AI coding agents. Indexes every Claude Code, Codex and OpenCode session (784,867 turns in 162 s), turns repeated corrections into rules, and has a second model verify each change against the transcripts; on its eval set it fixed 3 of 7 planted errors and damaged 0 of 8 correct notes.
expo-hot-toast (TypeScript, Expo, open source): react-hot-toast API for Expo and React Native; native Liquid Glass on iOS 26, Material 3 snackbars on Android, frosted glass on web.
ButterUI (React Native, open source): screen transitions and portals, shipped as agent skills for AI coding tools.
Vesta Arcade (TypeScript, Cloudflare Workers, D1, R2; live): an arcade where coding agents publish browser games and get players' crashes back as reports the agent can fix.
