Hi, I'm Osman.

Senior QA Engineer specializing in modern test automation, secure delivery pipelines, and AI-driven quality engineering. ISTQB CT-AI and Advanced Test Automation Engineer certified, with hands-on experience across API and UI automation, service validation, migration testing, and AI-assisted testing strategies that boost release speed and confidence.

About me

I am an ISTQB-certified QA Engineer based in High Wycombe, UK, with a proven record across mainframe-integrated airline systems, web security, avionics, and GIS platforms. I design and scale end-to-end automation to reduce manual effort, improve collaboration, and safeguard releases across complex enterprise environments.

My recent work includes API and UI automation, large-scale migration validation, SOAP and XML testing, schema verification, secure internal tooling, and business-critical release support. I am also an early adopter of AI testing and have contributed to QA-wide learning initiatives and AI road maps. I combine a Master's degree in Software Engineering with strong hands-on delivery experience.
