Building products that deliver real value…sometimes
I'm Yann — I go from idea to useful implementation fast, and I love crafting delightful experiences for communities I understand. I'm also just a hobbyist programmer.
About
Originally from Cameroon, now based in NYC. I studied Computer Science at Concordia University in Montreal, then worked at Shopify and Block before joining Google.
Outside of work, I'm into chess, salsa, powerlifting, and traveling — they fuel my projects. The best products come from genuine passion for the community you're building for.
Selected work
A few projects where I mix craft, research, and community feedback.
Ask your restaurant anything
An agent harness for restaurant ops — ask in plain English, get structured answers on sales, labor, and prime cost. Built with a query classifier, complexity-based planning, 6 data tools, and a full eval suite. Model-agnostic: swap between Claude, GPT, or any provider via config. Currently in beta.

Feel the rhythm, find the beat
A timing trainer for salsa dancers. Real-time BPM detection syncs with YouTube or Spotify, while a clock-based architecture ensures frame-perfect tap validation across any device.
