The Challenge: A QA bottleneck heavily slowing down development

JOIN Solutions operates a fast-paced development cycle where four engineering teams work concurrently on multiple projects. While their engineers maintain high standards using test-driven design, unit tests, and Cypress/Playwright for core "happy path" checks, all features must undergo thorough manual testing in a staging environment before being released to production.

This process created a severe bottleneck. JOIN’s three manual QA engineers were operating at maximum capacity, with each handling up to three projects at a time.

The Solution: Elevating QA Engineers into Quality Owners

JOIN did not want to replace human oversight with AI; rather, they wanted to give their QA engineers a tool that allowed them to do more without the heavy manual lifting. By partnering with QA.tech, JOIN transformed their QA engineers into "QA managers" who oversee automated AI agents.

The Results: Shrinking Regression from Weeks to Days

Ultimately, QA.tech allows JOIN Solutions to maintain their strict quality standards and safeguard their critical application flows, all while scaling their output and preventing QA from becoming a roadblock to their CI/CD pipeline.

Highlights

• Before: Manual regression testing took at least a full week per project. A team of three QA engineers was at maximum capacity, causing potential release bottleneck.
• After: AI agents handle repetitive staging regression tests, freeing QA engineers to focus on complex, high-impact validation, shrinking QA cycles and allowing manual testers to act as AI managers.
