Hey, I'm Hardeep!
IIT Delhi → AI Agent Builder
Team Lead and Senior AI Engineer at Squidgy AI (UK). I build agentic workflows that run in production: multi-agent systems, MCP services, and the tools agents use. Also co-founding Coffee Coach.
Here's a quick intro about me && what I love to do
From the lab to the internet
I studied Chemical Engineering at IIT Delhi — where I learnt to think in systems and optimize under constraints. What I didn't expect was that the most interesting problems I'd encounter were messy, unstructured, and sitting inside data. That's what pulled me toward software.
Now I build AI products that take that mess and make it usable — pipelines, tooling, apps.
Building things I actually want to exist
I like building things that solve problems for me, and seeing them become products that other people use. CoffeeCoach took off on Reddit without a single paid promotion. youtube-rag-scraper hit 78 GitHub stars because apparently a lot of people had the same frustration with video content being impossible to query. FluxRAG helped me understand RAG pipelines, eval and benchmarking which is enhancing my current AI Agent centric projects.
Life beyond the screen
I play chess obsessively. I played football every week until I tore my ACL last year. Still in recovery, still bitter about it. I befriend every mountain dog I meet. And I'm on an ongoing, probably never-ending hunt for the best chhole bhature in Delhi.
Building AI agents
At Squidgy AI I built Concierge, an MCP service that indexes 9 repos into a knowledge base — agents ask what lives where instead of re-reading code, saving 50-100k tokens per session. I also built SiteBuddy, an agent that rebuilds a website in 2-3 minutes for under $1 in token cost. Around 50 sites shipped.
Two concurrent contracts, 3,000+ organic users across shipped products, and 75+ GitHub stars on open-source tools. FluxRAG exists because I wanted to benchmark those tradeoffs properly before shipping anything.

IIT Delhi – Chemical Engineering
2013 – 2018
Chemical Engineering at IIT Delhi providing the analytical foundation for systems thinking and constraints-based problem solving.
Things I've built that people actually use.
agent-chrome
Browser MCPs pull Chrome to the front mid-sentence, and they can't get into the sites you're signed in to. agent-chrome gives Claude Code a copy of your signed-in Chrome that opens behind your apps and never takes focus. You keep typing while the agent clicks.
Ships as a Claude Code plugin. Built on mimkorn's chrome-pipe-proxy, with background windows and per-account profiles on top.
CallLane
Join a call on a Mac and macOS drops your music by about 20 dB. Your AirPods fall back to headset quality too. CallLane is a menu-bar app that gives call apps their own audio device, so the rest of your audio stays at full volume. It locks the input to your Mac's mic, so your headphones keep high-quality audio through the call.
coffeecoach.app
Most coffee brewing advice online is scattered and contradictory. I ingested high-quality brewing data, made a RAG pipeline on top of it, and built an agentic coaching system based on that data — LLM orchestration with feedback loops that adapt recommendations based on user input.
Wrapped it all in a full-stack AI coaching app.
splitwala
Can't get your friends to install the bill splitting app? This Telegram bot makes it a single command — /split, /paid, /balances. Lives inside your Telegram group. No app to download, no account to create. Built on the principle that the best UX is the one that gets out of the way.
youtube-rag-scraper
YouTube has some of the best domain-specific knowledge on the internet, but it's locked in video format, impossible to query or reuse. This pipeline bulk-scrapes transcripts, processes them, and structures them into a searchable knowledge base for RAG systems. Handles chunking, embedding, and retrieval quality out of the box.
