We catch it before your customers do.
QA and test automation for fintech teams, led by a senior engineer who has tested core banking, central bank payment rules and credit products. We work inside your release cycle.
Where we sit in your release
Caught in staging. A retry that charged the customer twice never shipped.
Fintech bugs cost money, not just time.
When the product moves money, a missed regression shows up as a refund, a chargeback or a question from your partner bank. These are the gaps we close first.
Wrong money in production
Duplicate payments on retry, conversions off by a rounding rule, interest calculated on the wrong base. We test the paths where money changes hands, end to end and at the API.
Releases outrun regression
New funding speeds up shipping, and regression lands on developers who would rather build. We take it over with a suite that runs in CI on every release.
No evidence for auditors
Regulators, partner banks and enterprise clients ask what was tested and when. We keep traceable test cases and results you can hand over.
Tested where the stakes are high.
Work we have done on regulated financial products, described without client names.
Rollout of Mambu at a Latin American bank
QA for retail and business accounts, with automated tests across APIs, microservices and front end.
Instant-payment dispute rules in Brazil
Test plan and execution for MED 2.0, the refund mechanism for fraud on Pix payments.
Credit recovery at a Brazilian digital bank
Planning, manual and automated testing for renegotiation, mortgage and government debt-relief programs.
Flaky E2E suite back to green
A regulated product's full end-to-end suite went from 11 unstable tests to zero, so the team trusts the build again.
