Learning Everything is a private engineering reference monorepo and the closest thing to a 'second brain' that actually runs. Instead of read-only notes, every fundamental relied upon (ML math, data pipelines, distributed-systems patterns, cryptography primitives) is implemented from scratch and again with real libraries, written three times over in vanilla-JS, TypeScript, and Python, and backed by 3,200+ passing tests under a 7-day audit cadence. On top of ~166 numbered lessons sit two reference applications: a multi-service chat platform and a NestJS 11 microservices interview-practice monorepo that demonstrates the transactional outbox pattern inside MongoDB transactions, Service Bus eventing, Redis, JWT auth, and Kubernetes — mapped feature-by-feature to a real senior-backend job description. It is where architecture is proven in isolation before it ships into any product, and it hosts the versioned Claude Code meta-prompts that automate the whole project portfolio. This is an internal reference library, not a deployable product.
