Fintech

Every number on the screen has to survive an audit.

We build the surfaces money moves across - order entry, reconciliation, lending, wallets. Eight decimal places for crypto and two for fiat, a session token that never reaches client JavaScript, and every figure reconciled before anyone is shown it.

Trade Ledger

Lending platform for commercial credit teams. Origination, credit assessment and the data behind both.

Acquired by United Fintech

Barclays

Internal banking tools with AI-assisted workflows and the integrations behind them, inside a tier-1 bank's existing systems.

Web3 wallet layer

Sign-In-With-Ethereum against a server-issued challenge, on-chain deposits tracked to confirmation, and a card on-ramp signed server-side.

What that means in practice

  • Trading and order-entry surfaces, with the states a real book has
  • Multi-currency money primitives - 8 decimals for crypto, 2 for fiat, reconciled history
  • Token-broker BFF: ~50 server-only endpoints, session token in a signed httpOnly cookie
  • Provider-agnostic integration layer - 10 domains, ~125 typed methods, repointable by env var
  • KYC and identity: Sumsub and KYCAID, shipped
  • Every handler degrades to a valid empty shape rather than collapsing the page
