Data Scientist
Tech Relieve
- Built and deployed a production voice AI agent that autonomously placed 50,000+ outbound calls in a month (13,000+ connected), running real-time qualification conversations over SIP telephony with a dual voice pipeline — Gemini Live (native audio, sub-400ms latency) and a cascade STT→LLM→TTS path — switchable per tenant on a multi-tenant platform
- Designed the post-call processing pipeline: LLM-based qualification extraction + a weighted 0–100 lead-scoring engine with cumulative cross-call blending, producing 25,000+ structured lead records per month
- Hardened the agent for real-world telephony — filler-audio latency masking when the LLM stalls>1.5s, and a silence watchdog that nudges an unresponsive caller and ends the call on continued silence to avoid runaway call cost — failure modes surfaced only by running thousands of live calls
Data Scientist
Aagati Pvt. Ltd.
- Built a production multi-tenant RAG system for an employee-benefits platform — hybrid retrieval (BM25 + Pinecone), a dual-index strategy, and a streaming voice interface (STT + multi-provider TTS) — answering benefit inquiries at 2–3s latency across partner organizations
- Developed an AI-powered ATS scoring engine combining a custom-trained spaCy NER (500 annotated resumes) with a fine-tuned Sentence-BERT matcher (6,000 resume–JD pairs) and a weighted scoring algorithm, plus a Twilio/WhatsApp candidate-engagement bot for automated interview scheduling
Projects
SaaS Helpdesk Voice Agent
- Built a multi-agent voice helpdesk demonstrating modern agentic patterns — a config-driven router/triage agent performs mid-call handoff to Account, Billing, and Technical specialists (LiveKit), with tool and agent registries that let agents be defined as data (prompt + tools + handoff targets), requiring no code changes to add one
- Engineered an async post-call LangGraph workflow — a stateful graph (summarize→classify intent→sentiment →conditional routing→ticket/persist) with a Postgres checkpointer and deterministic fallbacks, keeping the real-time call loop fast while moving agentic reasoning to the async layer
RAG over SEC 10-K Filings
- Built an end-to-end RAG system over SEC 10-K filings with hybrid retrieval (BGE vector + BM25 fusion) and cross-encoder reranking, returning streamed, source-cited answers via FastAPI/SSE
- Engineered domain-aware hierarchical chunking (split by SEC Item headers, table-preserving) on a clean interface/factory dependency-injection architecture (swappable LLM, vector store, and reranker via config); added voice + multilingual querying (Sarvam STT + auto-translate)
