📄 More about me
  • 🎓 M.S. in Information Systems (Data Science) — University of Maryland, Baltimore County
  • 🎓 B.E. in Computer Engineering — Savitribai Phule Pune University
  • ⚙️ Comfortable across Agile and Waterfall; happiest taking something from a blank repo to production.

⚡ Now — October 2026

  • 💡 Shipped Lampline v0.1.0, my self-hosted voice agent platform. Next up: one-command Google Cloud deployment and Genesys Cloud AudioHook, so contact centers can hand calls to self-hosted agents.
  • 🚗 ioniq6-pilot: first real-car tests of sentry mode and steering-tune feedback.
  • 🤝 Open to conversations about voice AI, contact-center automation and self-hosted LLM agents.

🏗️ How a call flows

The voice-agent architecture I design — in production on Dialogflow CX + Genesys, and self-hosted with Lampline.

🚀 Featured Projects

A mix of what I'm building in the open and the conversational-AI systems I've shipped in production.

Lampline

💡 Lampline — flagship, open source

A self-hosted voice agent platform: import your Dialogflow CX and CX Agent Studio agents, then build, test and take calls on your own hardware — for about $0.02–0.17 a call instead of $0.50.

  • Drag-and-drop builder that mixes LLM steps and scripted pages, with a live test console
  • 20 model providers (Claude, OpenAI, Gemini, Vertex, Bedrock, Ollama…) and phone/SIP via jambonz
  • Agents as code (YAML + Markdown) with the vk CLI · local-first, no telemetry · built on Pipecat

Stars Release Python TypeScript

The Lampline builder

🛣️ ioniq6-pilot

Rebased on sunnypilot

Personal openpilot build for a Hyundai Ioniq 6 on a comma 3X — NNLC steering tune, reverse-camera view, sentry mode and a phone dashboard, auto-rebased onto each new sunnypilot release. Python

🤝 HealthAssist — Production

Bilingual, cloud-native Dialogflow CX virtual agent on Genesys CX (us-central1/us-east1 redundancy) automating medical billing & records self-service. Deflects 20–40% of calls, ~85% lower contact-center cost, 24/7 availability.

🩺 Electronic Visit Verification Bot — Production

Multilingual caregiver visit verification over calls + SMS using Voximplant & Telnyx — real-time compliance tracking and streamlined reporting.

🤖 GenAI Suite — Production

GPT-4 + Flask chatbots and data-analysis tools that cut response times and turn large datasets into decision-ready insights.
