Ledger v3
// deterministic, content-addressed builds pub fn resolve(graph: &Graph) -> Result<Plan> { let roots = graph.topological()?; let cache = RemoteCache::connect("s3://forge")?; roots.par_iter() .map(|n| n.hash()) .filter_map(|h| cache.get(h)) .collect() } // 73% of CI time is now redundant work. // forge eliminates that — with proofs.
Forge — build system
Atlas — clinical ML
Kindred — journaling app
How we'll work together
A 30-minute call
You talk, I listen. We dig into the business problem behind the technical one — no jargon, no commitment.
A fixed proposal
Within 48 hours: milestones, timeline, and a price that doesn't move. You know exactly what you're buying.
Weekly demos
Working software every week, plain-English updates, and no surprises. You can pull the plug at any milestone.
Launch & handover
Deploy, docs, and a recorded walkthrough so your team owns it. I stay on call for 30 days after launch.
A career, in chapters
Strata Payments · Staff Engineer
Tech lead for the ledger and settlement domains. Drove the v3 rewrite (event-sourced Rust), set the hiring bar for the platform org, and authored the engineering ladder used for 40+ engineers.
Helix Health · Principal Engineer
Built Atlas — the clinical feature store that served 14 hospitals. Owned the team's path from prototype to HIPAA-compliant production, mentored four engineers into senior, and wrote the postmortem culture from scratch.
Kindred · Founding Engineer
Employee #2 at a journaling startup. Shipped the iOS + Android app, designed the offline-first sync protocol, and owned everything from Stripe integration to App Store reviews. Acquired by a wellness conglomerate.
Northwind Logistics · Senior Software Engineer
Owned the dispatch engine that routed 90k deliveries a day across 6 cities. Reduced last-mile costs by 23% through better graph algorithms and obsessively monitored SLOs.
Inkpad Studios · Software Engineer
Cut my teeth shipping client work fast — 30+ launches across e-comm, media, and government portals. Learned to sweat the scoping conversation harder than the code.
Self-taught · apprentice years
Wrote my first commercial code at 19 — a class scheduling app that ran for nine years. Learned to debug PHP at 1 a.m. with 40 simultaneous users. Still my favorite kind of pressure.
