Challenge

The product was growing fast, but testing was done by developers before each release, with no test plans or regression suite. Bugs regularly reached production, and patient-data access rules were never tested systematically.

What we did

We built a QA process from scratch: test plans, regression suites and release checklists for every user role. We tested web, API and mobile apps on real devices, including GPS and check-in flows, and added access-control checks against OWASP Top 10 and accessibility checks against WCAG 2.1 AA.

Result

Bugs dropped by 80%. Releases moved from a four-week to a two-week cycle, and production errors are now reviewed after each release and turned into regression tests.
