Backend engineer — performance-focused, looking to build well

I've outpaced every environment I've been in. School taught me documentation. Work taught me what it feels like to be held back. I'm self-taught in the things that matter: performance, clean architecture, readability, systems that hold up. I'm looking for a team where I can genuinely excel — one that raises the bar instead of lowering it.
