Sep 2026 – now

Backend AI Engineer · Reliance Intelligence Current

Building the intelligence platform behind Bharat AI, which makes AI accessible to Indian users at scale.

  • Onboarded cricket, music and news as capabilities on the platform's orchestrator agent, giving users real-time scores, playback and headlines in natural language.
  • Worked across the voice stack (speech-to-text, text-to-speech and speech-to-speech) and built services in a hexagonal (ports and adapters) architecture, with MLflow for model tracking.
  • Brought music to speech-to-speech (S2S) voice calls and handled barge-in: when a caller speaks over a playing song, playback stops and the agent responds.
  • Built a Watcher Service that monitors configurable events and proactively sends users contextual reminders, running on a workflow service built on Temporal for durable schedules and retries.

Backend Engineer · CRED

Built and scaled CRED Garage and Insurance from 0 to 1.

  • Grew the products to 7M+ users and ₹350Cr+ in annual revenue; ran services at ~1000 RPS and ~1M DAU with steady latency through traffic spikes.
  • Architected a cross-sellable pocket insurance platform across multiple lines of business: ~₹40Cr revenue.
  • Built a motor insurance assistance flow that lifted conversion by 13%, and a pluggable self-inspection platform that raised quote coverage by 11% with zero-effort insurer onboarding.
  • Hardened high-throughput insurance flows with circuit breakers, idempotency keys, retries with DLQs, Sagas and event-driven design on Kafka; distributed rate limiting on Redis; JVM and query tuning.
  • Shipped Garage features: challan details and payment, FASTag recharge and passbook, PUCC, a scraping platform, and car valuation with CARS24 and Spinny.
  • Shipped an on-call AI agent (OpenAI + RAG) that diagnoses incidents through MCP-exposed microservices, and an AI layer for KYC review that cut ops work by 30%.

Projects

Things I build for myself

Side projects, mostly AI agents and developer tools. Several are open source on GitHub.

Coding agent · open source

kmare-code

A coding-agent harness built from scratch, a smaller cousin of Claude Code.

The model is the brain; the harness is the body. A planner breaks the task down, a generator does the work with tools (read, write, run a command), and an independent evaluator checks the result before anything is called done. Point it at your test command and a failing run fails the round straight away.

  • kmare-voiceself-hosted push-to-talk: faster-whisper STT, Piper TTS
  • kmare-observabilitymetrics and traces for every LLM call

Voice assistant · open source

Escanor

A local, Jarvis-style assistant for the Mac, by text or voice.

One async agent sits behind a terminal, a web HUD and a hands-free voice loop. It keeps a second brain of notes with keyword and semantic search, runs reminders and calendar, plays YouTube Music as an AI DJ, teaches research papers, and plugs in any MCP server as a tool group. A permission gate asks before anything acts outside the chat, and web text is fenced as untrusted.
