Industries / FinTech
Financial infrastructure that regulators and auditors respect
Payment systems, lending platforms, and banking integrations built with the precision money demands — PCI DSS scope discipline, immutable ledgers, and reconciliation that balances to the cent.

Why fintech
An industry we know from the inside
In financial software, 'mostly correct' is a euphemism for 'wrong.' Ledgers must balance, every state transition must be reconstructible, and the audit trail is a first-class product requirement. We've built payment processing, lending origination, and treasury systems handling billions in annual volume.
We know the plumbing — ACH windows and return codes, card network rules, Plaid and banking-as-a-service integrations, KYC/AML workflows — and the failure modes that only appear at scale: duplicate webhooks, partial captures, and the timezone bug that shifts a settlement date.
The landscape
What's actually hard in fintech
The friction we hear in every first workshop — and the engineered answers we bring to it.
Correctness under concurrency
Double-spends, race conditions, and reconciliation breaks that surface only under production load — when they're most expensive.
Regulatory surface area
PCI DSS, SOC 2, state lending rules, and examiner expectations that change faster than roadmaps — with penalties measured in licenses, not dollars.
Legacy banking rails
Modern product ambitions negotiating with batch files, cutoff windows, and core banking systems older than the founders.
Ledger-first architecture
Double-entry, append-only transaction cores with idempotent operations — systems where the money math cannot drift.
Compliance-scoped design
PCI scope minimized through tokenization, audit trails generated as a side effect of correct architecture, and evidence collection automated for examiners.
Resilient rail integrations
Payment orchestration across ACH, cards, and RTP with retry semantics, webhook deduplication, and reconciliation jobs that catch breaks the same day.
