Who built this.
One engineer. Every number live, every commit public.
Dominic Baca. Senior engineer, 10+ years shipping production systems — solo. I built Domdhi.OS because freedom's a math problem: most people never run the numbers, so the numbers run them. Most finance advice won't show its math; most apps bury the one number that matters under forty that don't.
So I built my own — money, fitness, freedom — calculated honestly and running live. No team. No roadmap theater. No dashboard with 47 features I'll never open. Every number's live, every commit's public — even the ugly ones. All in, or not in; 200% or 0%: beat the salary grind on math I can defend — then hand the whole system to anyone grinding the same exit.
