Bite-sized micro-courses on the obscure but essential skills that separate shipping founders from stuck ones. API rate limiting, database indexing, Stripe webhook debugging, and more.
Choose from focused micro-courses on the technical gaps that actually block your next feature.
Each course is a single, dense lesson — no filler videos, no theory dumps. Just what you need to know.
Apply what you learned immediately. Every course ends with a concrete implementation you can paste into your codebase.
Each course is a single focused lesson you can finish during a coffee break.
Build a production-ready rate limiter with sliding windows. Token buckets, Redis counters, and the edge cases nobody warns you about.
Stop guessing which columns to index. Learn to read EXPLAIN plans, spot full table scans, and fix the queries slowing down your SaaS.
Handle webhooks without losing events or double-charging customers. Idempotency keys, retry logic, and local testing with the Stripe CLI.
Every course is written for developers who'd rather spend 15 minutes learning than 3 hours debugging.
