Trust · Quality assurance

Quality is gated, not hoped.

Nothing reaches your users on optimism. Every release passes a QA stack that runs the same way at 2pm and 2am - and a human still looks before anything customer-visible ships.

The testing stack

• Unit tests where the logic lives - calculation engines, permission checks, state machines. Written with the feature, not after it; part of the definition of done.
• Integration tests where systems meet - API contracts, database behaviour, third-party boundaries with recorded fixtures so external flakiness doesn’t poison the suite.
• End-to-end tests for the flows a customer would notice breaking: sign-in, the core workflow, payment paths. Few, fast, and release-gating.
• Regression protection. Every bug that reaches production earns a test that would have caught it. The suite grows where reality proved it was thin.

Beyond correctness

• Accessibility. Semantic HTML, keyboard paths, contrast standards, reduced-motion support - checked in review, not retrofitted. This website practises what we bill for.
• Performance. Budgets, not vibes: page-weight and response-time targets per product, measured on modest devices and real networks - the ones our markets actually use.
• Manual QA. Structured exploratory passes before releases: new-user eyes on real devices, trying to break what automation cannot imagine.
• AI-assisted QA. An AI review pass reads every merge for the misses tired humans make, and AI-generated test cases widen edge coverage - reviewed by engineers before they join the suite. The gate is shown on the architecture page.

Who owns quality

The engineer who builds it. There is no separate wall to throw code over - the person who wrote the feature writes its tests, watches its rollout and answers for its behaviour. Small-team accountability is the whole QA org chart, and it works because the pipeline refuses anything unproven.
