⚕ 100% Job Success-oriented work. ⚕ Open-minded person, ready to learn anything, easy to work with. ⚕ Self-motivated, strong organized, reliable, dedicated, fast learner and hard working iOS developer. ⚕ Excellent logical, analytical and computational skills. I’m an iOS developer with 3+ years of hands-on experience building apps end-to-end and shipping 30+ releases to the App Store. I mainly work in Swift (and use Objective-C when needed), and I’m comfortable taking a product from “Figma + API docs” all the way to a polished, stable production build. I work across both UIKit and SwiftUI, building clean, responsive interfaces with Auto Layout and modern state-driven UI patterns. I’ve implemented reactive flows with Combine and RxSwift, and I focus on making apps feel fast and reliable through careful performance work and stable architecture. My core interests are products where audio, AI, and real-world context matter. I’ve integrated OpenAI Whisper for transcription, built audio playback features with AVFoundation and AudioKit (including EQ/effects), and shipped location-based functionality using MapKit and Core Location. On the “production” side, I’m comfortable with secure authentication (Face ID / Touch ID, CloudKit), solid data layers (Core Data, Realm, Firebase), and scalable code structure (MVC, MVVM, VIPER where appropriate, SOLID, Clean Architecture). For networking, I’ve built REST API integrations with JSON using URLSession and Alamofire-style stacks, with proper error handling, retries, and clean separation between networking, domain logic, and UI. Design implementation: pixel-perfect UI from Figma, responsive layouts for all screen sizes Quality & performance: optimization, stability, clean code practices I care about shipping apps that don’t just work, but feel polished: clear UI, smooth interactions, maintainable architecture, and performance you don’t have to apologize for later.
