At Competo LLC, I developed and maintained production banking and fintech applications, implementing business functionality used by real customers. I built banking features with Swift, UIKit, SwiftUI, and Combine, and integrated the apps with REST APIs and financial backend services.
I also refactored legacy UIKit components and extracted reusable business functionality into Swift Package Manager modules and standalone frameworks. I contributed unit and UI tests, supported CI/CD pipelines, and used Xcode Instruments to investigate performance and memory issues.
At UnIT, I developed native iOS applications from scratch using Swift. I was the sole iOS developer on the CipherME project, responsible for its iOS implementation and App Store releases.
Earlier, at WIDE:UP(PINbank), I developed and maintained a production financial application, implementing business functionality and integrating REST services. At Zeus Electronics, I worked on iOS and macOS applications, including an existing digital magazine product and a macOS application for placing bids on eBay.
