Fintech
Payment flows, ledgers, onboarding and dashboards built for an environment where a rounding error is an incident and every action needs a paper trail.
Users forgive a clumsy interface before they forgive a balance that is wrong or a payment that vanished. Financial products are judged on correctness first and everything else second.
We design for that order of priorities: money handled as integers in an append-only ledger, idempotent operations, reconciliation as a first-class feature, and a clear answer to who did what and when.
Balances calculated on the fly from mutable records, with discrepancies found at month end.
Identity checks that take days, ask for the same document twice and give no status in between.
Webhooks dropped, retries double-charging, and failures surfaced by the customer rather than an alert.
No reliable record of changes, so every regulator or partner request becomes a forensic exercise.
Solutions
Money movement that is safe to retry and easy to reconcile.
Verification flows that satisfy compliance without bleeding conversions.
A single source of truth for balances, with the reporting on top.
Built in, not bolted on
We build in line with PCI DSS, SOC 2 and open-banking expectations and work alongside your compliance team and auditors. Licensing and regulatory sign-off remain yours.
Tokenised payments through certified processors so raw card numbers never touch your servers.
Immutable audit logs for money movement, permission changes and administrative access.
Secrets management, least-privilege roles, network isolation and dependency scanning in the pipeline.
Timeouts, duplicate webhooks and partial failures exercised in tests, not discovered in production.
Services
Multi-tenant products with billing, roles and onboarding built in from the first sprint, not bolted on before launch.

FAQ
Most often Stripe, alongside Adyen, Paddle, Plaid and regional processors. The choice depends on your markets, payment methods and fee structure, and we set that out in discovery.
We architect so that card data is handled by a certified processor, which keeps your own compliance burden as small as possible. We support your self-assessment with documentation of the architecture.
Yes. For anything holding customer balances we recommend a double-entry, append-only ledger and have a clear view of when to build one versus adopting an existing ledger service.
No. That needs a regulatory specialist. We work closely with yours and translate their requirements into software that can demonstrate it meets them.
