QA & testing

Quality BuiltInto Every Release

Testing at the end of a project finds bugs when they are most expensive. We embed QA from the first sprint: test strategy, automation in CI and clear release criteria.

Our QA engineers test web, mobile, IoT devices and AI systems, including trading platforms with real-time data, payment flows, and firmware on physical hardware.

Automation with Playwright, Cypress and Appium runs on every pull request, while exploratory testing catches what scripts cannot.
