About Me
"What I care about most is reliability. I want a framework I build to still work three releases from now, not just on the day I commit it. When a test goes flaky I'd rather find out why (timing, state pollution, data dependency) than rerun it until it goes green."
I work on QA and test automation for Pega applications, in the Sopra Steria Pega Practice (RulesMatter). Most of my background is in financial services, where release discipline and audit trails are hard requirements. I hold Certified Pega Business Architect (CPBA) and Certified Pega System Architect (CPSA), and in 2026 I certified as a Tricentis Tosca Product Consultant and a Tricentis Testim Product Consultant, both at Advanced proficiency. Languages: Turkish (native), English (C1) and Dutch (B2).
My Journey
Before Sopra Steria I spent two years at ING as a Test Automation Engineer on Dovetail, Fiserv's real-time payments platform. I built and maintained the shared Selenium, Cucumber and Java framework behind the daily regression suites, covering incoming and outgoing payment flows across multiple countries. I studied Applied Mathematics at Istanbul University, which shows in how I approach coverage, edge cases, and breaking scenarios into independent variables. I am also ISTQB Certified Tester Foundation Level (CTFL).
I think about what level a test should live at: end-to-end coverage is expensive, and a unit test doesn't always prove what people assume. Tosca covers model-based automation across web, API, desktop and mobile; Testim adds AI-driven web testing, and I am building out my web automation in Playwright. Combined with Pega, the aim is testability built into the case design from the start. Within Sopra Steria I work with AI Backbone, the group platform for AI-assisted software delivery, and I am developing Tosca skills and workflows for it so model-based testing gets a place in that pipeline. It builds on an open-source project I created earlier, the Devran AI Kit, which adds governance, quality gates and session-persistent context to tools like Claude Code, Cursor and GitHub Copilot. Both come down to the question QA always asks: what makes output trustworthy, and how do you make that trust auditable.
Through Sopra Steria I am available for QA Consultant, QA Lead, or Test Automation Engineer assignments in a Pega context, ideally where model-based automation in Tosca is the approach. My preference is financial services or government engagements. If this lines up with what you're working on, feel free to reach out. I'm always up for a conversation about testing real-time payments or scaling QA inside a Pega project.
