Project history

Developer - AI Developer Office Multi-Agent Harness

Personal Project
Building a multi-agent harness where AI agents work as a virtual developer team, with an agent manager, shared memory across agents and on-demand sub-agent creation. Architected as a layered platform: single-agent runtime, shared agent services and a multi-agent office for orchestration. Phase 1 runs read/extract-only agents with guardrails; write-capable coding agents are planned for a later phase. (In progress)

Developer - Project Knowledge Agent

Personal Project
Defining requirements for an internal Q&A agent that answers questions across all of the company's projects from a single interface using LLMs and RAG. (In progress)

Developer - Pre-Treatment Survey Voice Agent

Personal Project
Building a patient survey voice agent covering five health dimensions (mobility, self-care, usual activities, pain, anxiety) with an FAQ knowledge base using ElevenLabs Conversational AI. (In progress)

AI Voice Bot Developer (Software Development Engineer - L1)

Apollo HealthAxis, Apollo Hospitals Group
Building and running production voice agents on Apollo Care Console (AI PDCC, ProHealth Reminder, No-Show), reaching 100,000+ call minutes within 19 days of go-live. Owning the Anika and Asha agent platforms on LiveKit Agents SDK and Gemini Realtime. Co-built a voice-enabled web chat assistant for the Apollo Hospitals website. Shipping agents on ElevenLabs Conversational AI. Built agentic solutions using LLMs including a Hindi multi-agent voice system and tool-calling flows for live appointment booking. Integrated Apollo EDOC and Medmantra APIs, engineered a post-call CRM pipeline into Microsoft Dynamics 365, and designed PostgreSQL schemas. Built the SIP edge on Azure and ran call recording to Azure Blob Storage.

Developer - AI Personalised Chatbot

Personal Project
Built a conversational AI chatbot behind a responsive web interface using OpenAI API, LangChain, and Python. Fine-tuned models on Kaggle datasets in Google Colab to improve domain-specific accuracy.

Developer - Healthcare Credentialing Tracker

Personal Project
Automated provider credential tracking for a healthcare workflow using Google Apps Script and Google Sheets, removing manual entry and keeping compliance dates current.

AI Engineering Intern

Apollo HealthAxis
Built and deployed a real-time AI voice agent platform for healthcare calls with Python, LiveKit and Gemini speech-to-speech models. Cut agent start-up latency from 6-8 seconds to under 1 second by playing pre-rendered welcome audio while starting the LLM session in parallel. Integrated Tata and Exotel SIP telephony. Built interruption detection and speech cancellation for natural turn-taking. Designed backend persistence with SQLAlchemy and Alembic with load balancing for concurrent calls and transcript logging.
