How we build
01
Constraints are the spec. Tighter limits produce better systems — not more resources.
02
Execution is the only proof. Ideas are cheap. A working URL is not.
03
Small surface area, deep utility. One problem solved completely beats ten problems solved poorly.
04
Built globally from outside the center. Geographic constraints as strategic leverage, not excuses.
"The best systems are built by people who can't afford to fail."
