Build Notes

These are write-ups of projects I have actually built, not tutorial rehashes. Each one covers the decisions that mattered, the bugs that took the longest to find, and what I would do differently with hindsight.

The goal is the same as the rest of this journal: explain how something works underneath the surface, and capture the reasoning a senior engineer applies when the obvious answer stops working.
