cohort 27 — applications open until Aug 21

Merge yourself
into main.

A 16-week, full-time software engineering bootcamp. You branch off as a beginner, commit every single day, and merge back as a hired engineer. The whole curriculum is one git log — and week one starts at the first commit.

git diff you@today you@week-16

The diff, after sixteen weeks.

No videos to passively watch. You write code from day one, get it reviewed like a colleague — not a student — and leave with a shipped product and a reviewable history.

400+ hours of code writtenNot watched. Written, reviewed, rewritten.
1 capstone in productionReal users, real bugs, a real deploy story for interviews.
48 code reviews from senior engineersThree per week, every week, line by line.

cat week.sprint

Every week is a sprint: learn / build / ship.

Monday you learn it. By Wednesday you're building with it. Friday you ship it and defend your choices in code review. Pick a week to see the actual board.
