Lead Engineer at Rezolve AI · Kolkata, India

Open to freelance projects

I build voice AI and agent systems that hold up in production.

Lead Engineer at Rezolve AI. I design real-time voice pipelines, multi-agent architectures and the cloud-native backends behind them, with a bias for low latency and sensible running costs.

voice agent

Thursday at 4:30 with Dr. Rao? Booked. Want a reminder?

// a voice turn, end to end

What happens after you say hello.

  1. 01

    You speak

    Audio streams in over WebRTC

  2. 02

    LiveKit

    Real-time media transport

  3. 03

    Speech-to-text

    Azure Speech, streaming

  4. 04

    LangGraph agent

    Tools, RAG and business systems

  5. 05

    Text-to-speech

    Azure neural voice, streamed back

// what I work on

Voice, agents, and everything underneath.

Work with me

Real-time Voice AI

Streaming speech pipelines on Pipecat, LiveKit, WebRTC and Azure Speech, tuned for latency, recognition accuracy and natural interruptions.

user › any slots thursday?
agent › 4:30 is free. book it?
user interrupts → agent yields

Backend architecture

Django REST Framework and FastAPI services on PostgreSQL, MongoDB and Redis, with async processing that stays maintainable as it grows.

POST /v1/sessions 201
GET  /v1/menu?store=42 200
POST /v1/orders 202
queued → worker.process_order

Agentic AI & RAG

Multi-agent systems with LangGraph, tool calling and retrieval, connected to business systems through MCP and reusable SDKs.

route_intent
search_catalog (rag)
call_tool: check_stock
compose_reply

Cloud & DevOps

Azure, AKS, Docker, Kubernetes, Helm and CI/CD pipelines that make deploys repeatable and boring, in the good way.

build→test→helm→aks
rollout complete · healthy

MLOps

Packaging, versioning, deployment and monitoring workflows that take models from a data scientist's notebook to production.

recommender v12 · live
rag-retriever v4 · live
chatbot v9 · canary

Mobile & full-stack

Flutter apps with GetX on top of Django and FastAPI backends, from reusable UI components to CI with GitHub Actions.

Have a voice or agent problem worth solving?

I take on a small number of independent projects, and I’m always happy to talk shop.
