## About

```text
At DevTeam Inc., I led automation efforts for SmarterDX (Pieces), growing e2e regression coverage to ~85%. I own testing for new platform features and maintain Cypress e2e suites.

For SmarterDX, I partner with customers and developers in sprint planning and grooming to shape acceptance criteria and test scope. I also authored and maintained test plans and test cases.

On Ripl, I tested web, iOS, and Android clients and developed Python API tests that reduced the manual coverage burden on core endpoints. I also coordinated task allocation and mentored a junior QA.

At iTechArt Group, I tested ClassPass across iOS, Android, web, and admin-panel surfaces, and mentored and coordinated a QA team of 4. Earlier, as a freelance QA Tester, I tested UI/UX, HTML, and CSS for projects through Test.io.
