What I'm looking for

I'm looking to build maintainable, user-centered, high-performance frontend platforms, particularly in fintech and digital banking, while contributing to scalable architecture, reusable component systems, and Agile cross-functional delivery.

I've built scalable fintech and banking platforms at Innovance Consultancy, using React and TypeScript to support digital banking modernization.

As a Senior Software Developer in Frankfurt, I contributed to frontend architecture, reusable UI component systems, RESTful API integrations, and real-time financial services. I also improved release efficiency through CI/CD workflow optimizations.

Previously, I led frontend development for large-scale internet banking transformation projects in Istanbul. I coordinated Agile delivery, conducted code reviews, and helped migrate legacy banking systems to modern React and TypeScript architecture.

My earlier work includes full-stack development and freelance projects such as face detection and employee tracking systems. I focus on maintainable, user-centered, high-performance web applications.
