What I Build

Production AI systems, voice agents, and full-stack apps shipped to real businesses, not just prototypes.

AI Automation

Custom LLM pipelines and agentic workflows that eliminate repetitive manual work. From lead processing to document automation I build it production-ready.

  • Multi-step LLM pipelines
  • n8n / custom agents
  • API integrations
  • Reliable fallback handling

Voice AI Agents

Real-time voice agents with tool-calling, memory, and state. Same stack behind Zaya a live dealership agent running at Cyepro DMS.

  • Real-time voice interactions
  • Tool-using workflows
  • CRM / DMS integrations
  • Structured output + validation

Full-Stack Web Apps

End-to-end Next.js / React apps with clean APIs, auth, database, and deployment. Production-quality from day one not just a Figma mockup.

  • Next.js + TypeScript
  • Supabase / Firebase / PostgreSQL
  • REST & streaming APIs
  • Vercel deployment

Custom GenAI Features

Integrate AI into your existing product streaming UX, RAG pipelines, structured outputs, and tool routing. Proven 20–25% reliability improvements on live systems.

  • Streaming UX with fallbacks
  • Tool calling + routing
  • RAG / vector search
  • LangChain · LangGraph · PydanticAI

RAG Systems & MCP Servers

Build knowledge-grounded AI with RAG pipelines and custom MCP servers that connect your data to LLMs. From vector search to retrieval-augmented generation at scale.

  • RAG pipeline design & build
  • Vector DB (Pinecone, pgvector)
  • Custom MCP server development
  • Knowledge base integrations

Projects

Arohak Inc. (via Cognizant, J&J)

AI Engineer and Solutions Architect

Designed the end-to-end architecture for a secure enterprise RAG pipeline retrieval strategy, schema validation, structured output contracts, and multi-stage document workflows. Defined reusable agent architecture standards (tool contracts, output validation, prompt structure) and built n8n automation workflows with webhook-driven agent triggers. Led technical hiring for GenAI engineer roles and mentored junior engineers on production-readiness.

Cyepro Solutions

Generative AI Engineer

Architected and shipped Zaya, a production real-time voice AI agent for a US auto dealership DMS platform, handling 500+ daily customer interactions. Designed the full voice pipeline STT ingestion, LLM tool-calling, TTS delivery, real-time turn management on LiveKit Agents. Built multi-tool agentic workflows with dynamic routing and memory-driven conversations, plus resilience patterns (timeouts, retries, fallback routing) and the full DMS integration layer.
