What I'm looking for

I'm available for an immediate start and am looking for a mobile development role where I can build user-centered, responsive apps using a product-focused approach.

At Wio Bank, I developed features and resolved bugs across structured products, instrument search, portfolio creation, and wealth portfolios for Wio Invest. I reduced reported error rates by 10% and raised unit-test coverage in low-coverage modules to 75%.

At Bayzat, I worked on B2C health services and AI-powered features, including a document-search and summarization hub, streaming chat interfaces, and an LLM-powered writing assistant. I also integrated Google Fit and HealthKit for wellness challenges and reduced crashes in health services by 9%.

Earlier, I developed GetirWater for Android and worked on Beko’s HomeWhiz smart-home app, integrating devices and connectivity features. At MilSOFT, I improved a Java message parser, reducing CPU usage by 15% in a module released to another team.
