Financial Systems Engineering for Software Where Correctness Is Non-Negotiable
I work on the financial infrastructure where mistakes have dollar amounts attached: ledgers, payment processors, trading systems, reconciliation engines. I bring integer arithmetic discipline, idempotency guarantees, and testing strategies that treat auditability as a first-class requirement—not an afterthought.
// What You Get

// Why This Works
Why teams bring me in for financial systems engineering
Production financial systems in Erlang and Go with zero float-related incidents
Ledger implementations that balance to the penny across concurrent transactions
PCI-DSS adjacent experience with audit-friendly architectures

If you're building anything where money moves and needs to be accounted for, you need someone who's done it correctly. Not just conceptually—down to the integer overflow checks and race conditions.
