The reality on the ground

## What fintech teams are actually dealing with.

Compliance velocity vs. product velocity.

Every feature touches audit scope. You need engineers who ship without forcing a SOC 2 rewrite.

Sponsor bank timelines.

BaaS contracts don't care about your sprint. Integration quality shows up in month-end reconciliation.

Ledger integrity at scale.

One off-by-one in reconciliation and finance spends the week in spreadsheets.

Where we plug in

## Payments, ledgers, cards, rails.

Our engineers have shipped production code against sponsor banks, processors, card programs, and crypto rails. They understand double-entry, idempotency, and why a retry queue matters more than a feature flag.

Payments & rails

ACH, wires, RTP, FedNow, local rails. Integrations with processors, not just webhooks.

Ledger & reconciliation

Double-entry accounting systems, journal engines, flow-of-funds modeling.

BaaS & card programs

Treasury Prime, Direct-to-bank, Lithic, Marqueta. Issuing, authorization flows, settlement.

Stablecoin rails

USDC/USDT on/off-ramps, cross-border, custody, wallets. Treasury flows across on-chain and fiat.

Industry fluency

## The language we've shipped against.

Not keywords on a résumé — systems, standards, and vendors our engineers have worked inside of in production.

Roles we staff most

## The profiles fintech teams ask us for.

Ledger & backend engineers

Double-entry, idempotency, reconciliation at scale.

Payments integration devs

Processor APIs, webhooks, retry queues, sandbox-to-prod parity.

Fraud & risk engineers

Rules engines, signal ingestion, decisioning pipelines.

Core banking integration leads

FIS / Fiserv, file-based workflows, ISO 20022 migrations.

The bar we hold

## Fintech-grade defaults.

01

SOC 2–aware from day one.

Audit-trail logging, least-privilege access, evidence-ready change management.

02

PCI scope-limitation by default.

Cardholder data never touches systems that don't need it. Tokenization-first thinking.

03

Ledger-safe defaults.

Idempotency keys, retry semantics, and immutable journals are our starting point.

04

BAA/NDA-ready onboarding.

Legal, compliance, and background-check processes move in parallel with engineering matching.
