I build user-centric fintech iOS apps in Swift, from payments and lending flows to reliable core modules.

I'm building user-centric iOS products for fintech, most recently on Revolut's Rewards & Referrals surfaces in a large modular, Bazel-based retail app codebase.

At T-Bank, I rebuilt the BNPL instalments experience end to end, partnering with product, design, and analytics on a UI redesign and reworked application flow. Monthly revenue for the product line roughly tripled after launch.

I also built and maintained payment features for T-Business, serving 720k+ monthly active users, led a migration to Swift 6 and Swift Concurrency across core modules, and reduced open incident resolution time by 2.5× through a weekly reliability sync.

Outside fintech, I built Eye, a vision assistant for visually impaired users using real-time OCR, object detection, spoken feedback, and ARKit distance hints. I hold a Software Engineering degree and have also completed retraining in methods of machine learning.
