Financial software built to the standard that money requires.
Fintech development requires specific competence: payment processing, compliance considerations, audit logging, data accuracy requirements, and security standards that go beyond standard web applications. Getting it wrong is expensive.
Need a fintech developer — payment processing, financial data, lending, insurance, or accounting software
Fintech applications have requirements that other software doesn't:
Data accuracy: Financial calculations must be exact. Floating-point arithmetic errors in financial calculations are inexcusable. Use decimal types (not floats) for all monetary values. Store amounts in cents (integer), not dollars (decimal).
Audit trail: Every financial transaction needs a complete, immutable audit log. Who initiated it, when, what amount, what status, what changed. This is both a regulatory requirement and a debugging necessity.
Idempotency: Payment processing requests can fail mid-way. Retry logic without idempotency causes double charges. Stripe idempotency keys prevent duplicate charge creation.
Reconciliation: The application's record of transactions must match the payment processor's record. Reconciliation tooling is necessary from early on.
Security requirements: Financial data attracts attackers. Encryption at rest, TLS in transit, minimal data retention, and proper access controls are baseline requirements.
Compliance awareness: PCI DSS for card payments (Stripe handles cardholder data, so PCI scope is limited), SOC 2 for B2B financial data, GDPR for European users.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
Fintech scope is the financial flows and compliance requirements. Fixed-price after specification.
Questions, answered.
For most fintech products: no. Using Stripe (for payments) or Plaid (for bank data) means you're not holding funds — the regulated entity is Stripe or the banking partner. Consult a lawyer for your specific model.
