What actually makes you senior (Matheus Lima)

Posted on Dec 19, 2025

Senior engineers look at the big, messy, abstract thing and start digging:

  • They ask questions nobody else thought to ask.
  • They separate what matters from noise.
  • They identify what should be done now vs. what to punt.

And you know what’s funny? When senior engineers do this well, it looks easy. Like nothing was even done. The project just… goes smoothly. Fewer surprises, production fires, or emergency meetings. But what actually happened was that someone did a lot of invisible work upfront.

💯 Absolutely perfect, spot-on analysis.
