About Me

Engineer. Builder. Forever Red.

I'm an Agentic AI Engineer based in Vancouver, Canada, originally from Bangalore, India. I studied Electronics & Communication Engineering at Birla Institute of Technology, Mesra (2010-2014) and have spent 12+ years building production systems.

I shipped a generative AI voice agent (Sadie) into production across 15,000 restaurants handling 2M+ calls. My journey spans fintech at Oracle, BI tools at Eka, hosting infrastructure at Newfold Digital, co-founding Qwackly, supply chain orchestration at Udaan, and AI voice-agent systems at MonkeyMedia/ezCater.

Now I build agentic systems independently and take contracts. I'm running Shorts4U — a multi-agent AI video studio, and ManU4U — a sports intelligence platform for Manchester United fans. When I'm not coding, you'll find me watching the Red Devils, playing tennis, or listening to the Lex Fridman podcast.

Founder & Founding AI EngineerFounder Jan 2026 - Present
Shorts 4 U
Vancouver, Canada
  • Building and operating two agentic AI platforms end to end, across two deliberately different stacks to prove the orchestration patterns transfer
  • shorts4u.ai — Multi-agent video generation pipeline: separate agents for script, hook, storyboard, image generation, and video generation, coordinated with state carried between stages
  • Built validation checkpoints between stages so a weak hook or off-brief storyboard fails early, before it burns on image and video generation downstream
  • ManU4U — Multi-agent sports intelligence system doing tool-based reasoning over live fixtures, events, and statistics APIs with RAG pipeline over an ingested historical corpus

MonkeyMedia Software (formerly ezCater)
Vancouver, Canada
  • Led the design and delivery of Sadie, MonkeyMedia's first production generative AI voice agent — went live across 15,000 restaurants with 2M+ calls completed
  • Built RAG-style context enrichment pipelines that pre-fetched order history, menu, and store metadata, grounding responses and satisfying 90% of user queries without escalation
  • Developed the evaluation and guardrail framework behind the agent — scoring response quality, tool selection accuracy, and hallucination rate
  • Re-engineered Authentication Server v2 on Spring Boot 3, OAuth2, OpenID Connect, and Azure Key Vault, lowering auth failure rates
  • Improved core platform reliability with OpenTelemetry instrumentation, Azure dashboards, RBAC and Managed Identity, and Terraform for infrastructure as code

What I'm Building

Production systems and ventures I've built.

Sadie AI
Featured · Production

Sadie AI

MonkeyMedia's first production generative AI voice agent. Built the orchestration layer sitting between speech-to-text and text-to-speech in Java and Spring AI, with a tool registry that lets the agent invoke production APIs for order history, menu retrieval, and store metadata. Live across 15,000 restaurants with 2M+ calls completed. Learn more.

Shorts4U
Featured · Active

Shorts4U

A studio for serialised AI video. Multi-agent pipeline — separate agents for script, hook, storyboard, image generation, and video generation — built with Python and FastAPI with Langchain stack as the AI orchestrator. Validation checkpoints between stages catch weak hooks or off-brief storyboards before they burn on downstream generation. shorts4u.ai · Studio

ManU4U

Multi-agent sports intelligence system for Manchester United. Tool-based reasoning over live fixtures, events, and statistics APIs. RAG pipeline over an ingested historical corpus with vector embeddings and guardrails for factual grounding. Also available as an MCP for universal agent integration. manu4u.com
