Udit Kumar

AI Engineer — LLM agents, RAG and evaluation · Solo founder, Delhi

I build AI systems that run in production, and I measure them before I make claims about them. My support agent answers real customers for the D2C brand I run; my productivity app is my daily driver. Not tutorials, not demos — tools solving real problems, most of them mine first.

🎯 Open to remote AI engineering roles — LLM agents, RAG, evaluation, applied AI products.


🟢 Live in Production

Project What it does Stack
GlamShelf Twin AI support agent for my own D2C brand — answers Instagram & WhatsApp DMs, routes each one AUTO / DRAFT / ESCALATE, and hands off to me on Telegram. RAG over store data, an output guard on prices and policy claims, and an LLM-as-judge eval harness Python · Flask · DeepSeek · fastembed + sqlite-vec · Telegram
Prism AI-native productivity PWA — tasks, notes, reminders, workout logging, SM-2 flashcards generated from notes, PDFs and YouTube. Offline-first Next.js 14 · TypeScript · Supabase · Groq Live demo ↗
The Glam Shelf D2C false-eyelash brand I run solo on Shopify — 1,000+ orders Shopify · Razorpay · Shiprocket Store ↗

🔬 ML & Evaluation

Project What it does Stack
taste-engine Music recommender over a year of my YouTube history (40,619 plays). Beats a most-played baseline on nDCG@20 in all 3 held-out periods under nested tuning — and the README documents every time the harness caught its own measurement error, plus six ideas tested and rejected Python · sentence-transformers · HDBSCAN · YouTube Data API
agentgrade Rubric-driven LLM-as-judge CLI for support-agent transcripts — tone, accuracy, compliance, resolution. Works with any OpenAI-compatible provider Python · LLM-as-judge

🤖 Automation

🧠 How I Build

  • Evaluate before claiming — held-out splits, human-labelled eval sets, and judges checked against human verdicts. When a fancier option loses to a simpler one on the numbers, the simpler one ships.
  • Agents that ship — intent routing (AUTO / DRAFT / ESCALATE), human-in-the-loop approval, output guards, real webhooks and payment/fulfilment integrations.
  • Debug from the data — production incidents traced through database state, cron and HTTP logs, not guesses.
  • End-to-end ownership — from Postgres schema and Row Level Security to PWA service workers, deploys and CI.
  • Agentic-IDE fluent — Claude Code and Google Antigravity, driven by written briefs and verified live.
