Notes from a developer who overthinks semicolons.
Hi, I’m Aashish, a developer who documents his confusion so others can skip it. Most of what I write starts as a messy Notion page, but ends up as something other devs can actually use. Currently obsessed with integrating Typescript/React/Next with Laravel and making code readable enough that future me won’t file a bug report. Occasionally seen holding a guitar and pretending it’s therapy.
