A Software Dev's Declassified Development Survival Guide

The stuff CS classes skip: Git that doesn't scare you, deploys that don't break at 2 a.m., and CI you can actually read — taught with widgets you poke at, not walls of text.

Why this exists

Computer science programs teach algorithms, data structures, and theory. They don't teach you how to work in a real codebase, use Git properly, deploy an app, or debug something in production at 2 a.m.

Those skills aren't secret — they're just scattered across Stack Overflow, blog posts, and things senior engineers mention in passing. raindev.fyi collects them in one place, with widgets you actually use.

Our mission

By the end, you can:

  • Open a pull request without sweating
  • Get localhost onto a real domain
  • Read a red CI build and fix it
  • Containerize an app with Docker
  • Keep secrets out of your repo
  • Debug production at 2 a.m.
