Available to hire
I’m Nikita Navarenko, a senior iOS engineer driving the entire lifecycle of smart-home apps—from architecture to App Store release. I rebuilt the app’s architecture using SwiftUI + MVVM, reduced bugs, and boosted development speed by 30%. I launched a full UI redesign (from Figma to SwiftUI) and introduced BD UI, enabling 40% of new features to ship without App Store updates. I lead cross-functional collaboration, deliver polished UX, and maintain robust code quality across teams.
I’ve developed and shipped iOS solutions for online orders of medical supplies and corporate courses, with Apple Pay integration, BLE pairing, and watch connectivity. I built a SwiftUI-based financial chart simulator with candle/volume graphs, playback mode, and offline OHLC data parsing, and I routinely refine requirements into robust, scalable features while keeping timelines predictable.
