Curated courses
Guided projects
Each project is picked so its spotlight technology is load-bearing — the build would fall apart with the wrong tool. That's the lesson the TechFit ratings make explicit.
Aurora Commerce
An e-commerce backend where checkout is one ACID transaction — overselling becomes impossible.
Helix Assistant
A document Q&A assistant that answers from your own files — streamed, grounded, with citations.
Ticker
One price tick reaches every open dashboard in order; offline clients replay what they missed.
Catalens
Snap a product; Gemini reads the photo and Atlas Vector Search matches it to your catalog.
Vitals
An offline-first fitness tracker whose hard parts live once in Kotlin and power two native UIs.
Concord
A real-time collaborative editor where concurrent edits always merge — CRDTs retire "last write wins".
