Product architecture, TypeScript README, and blog distribution
A day of reviewing architecture in real projects, organizing the TypeScript playground, and turning a recent post into reading prompts.
The day was smaller, but it still had three useful threads: understanding product architecture, improving the typescript-playground presentation, and preparing distribution for a recent blog post.
Architecture in real projects
In itop.com.br, I reviewed state and authentication decisions. The main question was why one part of the flow uses React Context while another uses Zustand, and how that connects to request authentication.
I also went back through the project's general architecture. This kind of reading matters because it helps me answer technical questions from the system, not from loose theory.
TypeScript playground
In typescript-playground, the focus was updating the README and making the organization easier to read. The repo now explains the split between fundamentals, intermediate, advanced, and design patterns more clearly.
There was also structure cleanup to keep src less confusing and closer to the goal of the project: a study and practice environment, not an app with folders growing without direction.
Blog distribution
On the website, I worked on distribution for the post about cognitive distortions for engineers. The task was to turn the argument into short LinkedIn and Twitter prompts in English, without losing the main thesis: agents help more when the engineer keeps judgment.
I also checked whether there were new daily entries to publish. The journal routine works better when the backlog does not become a black box. Even on smaller days, reviewing the flow keeps the system alive.
It was a day of organization. Few large changes, but several small decisions that make the repos easier to explain.
