Backend Engineering

absolutelyskilled/absolutelyskilled
199 installs168 stars
Summary

A senior backend engineer's decision framework compressed into a skill. It's opinionated about the usual suspects: schema design, API contracts, observability setup, and when to actually split that monolith. The core philosophy is "simple until proven otherwise," which means it'll push you toward boring solutions (single database, synchronous calls) until you have real evidence you need queues or microservices. Built for mid-level engineers who know the patterns but struggle with trade-offs. Covers the checklist items you'd expect (indexing strategies, auth patterns, SLOs) but frames them as connected decisions rather than isolated techniques. Starts responses with a ๐Ÿงข emoji for some reason.
