What Happens During Phase 04?

A fast website that crashes under load or leaks user data is worse than no website at all. In Phase 04, our dedicated QA engineers subject your application to end-to-end automated testing, cross-browser compatibility checks, OWASP top-10 security scans, and database load simulations. We fine-tune server caching, image delivery, and bundle sizes until the application achieves 95+ Google Lighthouse scores.

We rigorously stress-test every workflow, execute automated regression suites, eliminate security vulnerabilities, and optimize for top-tier Google Core Web Vitals.
