GreeceWhat I'm looking for
I am an ISTQB-certified Senior Test Automation Engineer with 10+ years designing and leading test automation across regulated industries including fintech, pharma, and gaming.

At Kaizen Gaming I led an iOS overhaul that reduced suite failure rate from 60% to 20% and raised iOS automation coverage from 10% to 20%. At Pfizer I built regression suites that cut testing time by 30% and improved bug detection and production quality by 25%.
I have led large-scale testing transformations (Accenture) across many product teams, implemented GMP-compliant test plans in pharma, and mentored global and junior engineers to foster continuous improvement and quality best practices.
I am an EU citizen based in Thessaloniki, Greece, open to senior engineering opportunities onsite or remote in Switzerland, Germany, Belgium, and Luxembourg, and I bring a pragmatic, metrics-driven approach to raising automation coverage and shortening release cycles.
