I build fast, reliable web systems - and the tooling that keeps them honest.
This is the real profile.ts that powers the hero. Flip a boolean or change the accent and the page updates live.
A self-contained demo of the kind of tooling I build - here, a refactor pass that streams a cleaned-up rewrite with a short rationale.
Refactor sandbox
pick a snippet, watch it get cleaned up
function getActive(users) {
var result = [];
for (var i = 0; i < users.length; i++) {
if (users[i].active == true) {
result.push(users[i].name);
}
}
return result;

Three projects, each with the problem, the approach, and the numbers that came out of it.
The old ledger reconciled once a night, so balances were stale all day and disputes took 48 hours to resolve.
Moved settlement onto an append-only event log with idempotent consumers, added read models for instant balance lookups, and shipped a replay tool so any account can be rebuilt from history.
Building developer tooling and exploring how local-first sync changes app architecture.
Shipped LedgerWave's streaming ledger and mentored two engineers through their first on-call rotations.
Open-sourced Relay CLI; it now runs releases for a handful of small teams.
