Review

We required continuous QA support to keep pace with our rapid growth while minimizing software defects. With a small team, we needed to maintain development speed without compromising on quality. DeviQA’s solution was the ideal fit. A dedicated QA engineer seamlessly integrated into our team, participating in daily standups, accessing our GitHub, staging, and production environments, and collaborating with product leads and engineers to fully understand project requirements. Using our ticketing system, the engineer managed tasks and delivered comprehensive bug reports with reproduction steps, fixes, and video captures of issues. In addition to manual testing, the QA engineer managed a suite of automated Selenium tests, running them daily to identify issues and promptly report them for remediation on our staging server. His integration into our team was flawless, with availability on Slack during overlapping business hours and fresh QA feedback at the start of each workday. DeviQA's service exceeded our expectations and there were no challenges. We only ended the project when we had the resources and budget to hire an in-house QA engineer.
