A few weeks ago, I had zero Apify actors. Now I have seven, all published on the Apify Store, monetized with pay-per-event pricing, and slowly building a passive income stream.

I have taken over codebases and had codebases taken from me. The experience in both directions has converged on one principle: a durable system communicates intent, not just implementation.
Naming that explains purpose. Architecture that encodes constraints. Tests that document behavior, not implementation. The goal is a codebase where a newco...
Design tokens are not CSS variables. This distinction sounds semantic, but getting it wrong produces systems that serve neither designers nor developers.
When teams generate tokens from Figma and map them 1:1 to CSS variables, they end up with --color-blue-500 everywhere. This is an implementation detail, not a token. A token is a decision: <...
