Security & trust
Security is an architecture decision.
Most of our work touches money, inventory or customer data. These are the practices we apply by default — illustrated in our case studies.
Untrusted input stays untrusted
Browser callbacks, webhooks and form posts are verified server-side — signatures checked, amounts and identifiers matched — before anything changes state.
Exactly-once where it matters
Payments, fulfillment and redemptions use idempotency keys and atomic state transitions, so retries and races can’t double-charge or double-deliver.
Card data stays with payment providers
We integrate PCI DSS–compliant payment providers and gateways so card details are handled by them, not stored in the systems we build.
Least privilege and isolation
Per-tenant data isolation, scoped credentials and secrets kept out of code and client bundles.
Fail closed, degrade gracefully
When a dependency misbehaves, risky operations stop (kill switches, circuit breakers) while the rest of the system keeps working.
Collect less, keep it shorter
We collect what a feature needs, set retention periods and honor deletion requests. Our own products are designed to keep customer data on customers’ devices where possible.
