AI Engineer | Building Voice AI, Agentic AI Systems & Full-Stack AI Products

Hey, I'm Darsh.

I build real-world AI products — from real-time voice agents and agentic workflows to scalable full-stack applications. I enjoy working at the intersection of LLMs, product engineering, system design, and automation. Currently exploring opportunities where I can build impactful AI products at scale.

Building AI systems that actually solve problems — not just demos.

About Me

I'm an AI Engineer and Full Stack Developer who enjoys building intelligent systems that feel practical, fast, and useful.

I like building complete products end-to-end rather than isolated demos. I've worked on production CRM systems, payment integrations, scheduling systems, collaborative real-time apps, and AI-native products.

What excites me most is building AI that interacts naturally — voice conversations, autonomous workflows, retrieval systems, and real-time experiences.

Not just a list of projects — the thinking behind each one. The problem, the constraints, the architecture, and what actually came out the other side.

Stuff I've Built

Voice AI

Self-Improving Voice AI Sales Agent

Full-duplex multilingual voice sales agent (Silero VAD → Sarvam ASR → Gemini → streaming Sarvam TTS) grounded on gated Qdrant RAG — with an offline "Dream Engine" that self-improves the bot from failed calls when no one is on the line, auto-injecting approved prompt fixes into the next conversation. Barge-in, 11 Indian languages with mid-call switching, and per-provider token isolation.

Agentic AI

LawAI – Agentic Legal RAG

4-way hybrid retrieval RAG (BM25 + semantic + exact phrase + metadata) with RRF reranking for Indian legal documents. Source citations and verification mode.

SecondSelf.ai

Autonomous AI meeting agent that joins calls as your representative — live transcription, voice conversation, RAG-grounded memory, and post-meeting action items pushed to Notion.
