What I'm looking for

I'm open to remote QA automation opportunities where I can own quality end to end, expand automated coverage, test APIs and payment workflows, and collaborate closely with international product and development teams.

At OPTIMMUS, I build and maintain around 200 Endtest automated end-to-end tests across QA, Staging, and Production. Running three times daily, the suite replaces about four hours of repetitive manual regression work and catches defects before release.

I own QA from requirements analysis and test design through execution, defect management, validation, and release readiness. I test complex payment workflows, create Postman REST API tests, and work directly with US-based clients and development teams.

Previously, I supported international remote teams at MODSQUAD and Appen across functional testing, customer issues, web research, and data validation. I'm continuing to expand my automation skills with Playwright, JavaScript, and TypeScript.
