The junior bar moved in 2026. OwlHub is how you clear it — building real systems with AI assistance, the way actual teams work.

OwlHub starts with our Java Backend Engineer — AWS track. Across 34 progressively harder hunts, you build a real-world clinic management system — from a Java CLI to a multi-service cloud deployment on AWS. Spring Boot, Docker, Terraform, SQS, monitoring, the works. By the end, your GitHub looks like five years of professional engineering — because that's what you actually did.
You'll ship every hunt using our SPARC workflow — the spec-driven, AI-assisted way senior engineers actually ship.

More tracks coming: Python + AWS, Java + GCP, and our 66-hunt GenAI & Agentic AI track.
Bring your squad, or join one. They see your progress, help with your doubts, and lose momentum when you do.
Every hunt trains you on SPARC — the spec-driven, AI-assisted workflow senior engineers use to ship in production. You don't just learn to code with AI. You learn to ship with it.
Consistent, rigorous, objective feedback on every submission — your architecture, your code, your decisions, your workflow. Not a test runner. A real review.
Sign up, join a squad, ship your first hunt this week.
