What I'm looking for

I seek a leadership QA role focused on automation, IoT and security testing in an Agile environment where I can mentor teams, drive quality, and implement continuous improvement.

I am an ISTQB-certified QA leader with 17+ years of hands-on experience across desktop, embedded, web, and mobile applications. I combine deep technical testing knowledge with a strong record in team leadership and delivery.

I have 8+ years building and maintaining automation frameworks and test suites using Selenium WebDriver, Protractor, Robot Framework (Ride), Ranorex, Cypress, and TestCafe, and I regularly use Postman for API validation.

I have led global testing efforts and acted as the final quality gate for product releases, managing teams across regions and delivering IoT projects that included LoRa/LoRaWAN pre-certification RF testing and web platform E2E testing. I mentor engineers, evaluate automation tools, and drive process improvements to shorten release cycles.

I work comfortably within Agile and Waterfall SDLCs, and I bring security-focused testing experience (OWASP Top 10) plus cloud and networking familiarity. I seek to apply my automation, IoT, and security expertise to help organizations raise product quality and accelerate delivery.
