Serhii Prykhodko

I’m an iOS developer with 5+ years of experience building, maintaining, and enhancing mobile applications using Swift and Objective-C. I work confidently across complex client-server architectures, and I’m especially driven by improving legacy codebases without sacrificing delivery speed. Coming from QA Engineering, I bring a quality-first mindset to every feature I ship in Agile environments. One of my biggest strengths is modernizing existing iOS applications with modern iOS practices like Swift, Combine, and SwiftUI—improving maintainability and reducing technical debt. I’ve contributed to complex client-server features and helped migrate an application to Apollo (GraphQL) to keep it consistent with platform standards. I also focus on stability by resolving production issues and extending unit test coverage. I’ve delivered work in both small and large cross-functional teams, including a Strong Middle role on an enterprise sales app and a Junior role on a booking app for travelers. In those projects, I refactored legacy code, built/maintained complex features, participated in code reviews and technical decision-making, and collaborated with product managers, designers, and backend engineers to clarify requirements and deliver timely releases.
