Hi, With over 10 years in the IT sector, I specialize in mobile app development for both iOS and Android platforms, as well as in related disciplines such as management, design, and backend development. I've had the pleasure of working with both small and large startups across various sectors like IoT and eCommerce. I can guide you through the entire app development process — from designing UI and code architecture to development, testing, and eventual publishing and support. I place a high value on ownership and transparency, allowing me to maintain long-term relationships with several clients over the years. What drives me is the desire to create something of value, executed using the most efficient resources and technical solutions. Clean, readable code, well-thought-out architecture, and automated tests not only bring me joy but also result in reliable and easily maintainable code for my clients.

I've shipped a production fitness app to the App Store and worked as an iOS developer at a fintech company both involving real users, real deadlines, and production-grade code. If you need iOS work done right, keep reading. iOS developer with 2 years of production experience in Swift, SwiftUI, and UIKit, working across consumer fitness apps and enterprise fintech platforms, end to end. ------------ What I Bring to the Table - StoreKit & subscriptions : App Store submission, product IDs, trial config, sandbox testing, RevenueCat - Analytics integration: PostHog, environment-keyed configs, strongly-typed event models - Modular architecture: Swift packages, xcconfig multi-env, MVVM + Combine - Media & video: AVFoundation, cached playback, looping, autoplay state machines - Backend integration: REST APIs, Supabase, Firebase Auth & Firestore - Onboarding flows built to convert and retain users - Custom animated UI with SpriteKit and SwiftUI transitions - Theme systems with dynamic dark/light mode support ------------ Stack Swift, SwiftUI, UIKit, Combine, AVFoundation, MapKit, StoreKit, SwiftData, Core Data, Keychain, SPM, CocoaPods, Git, MVVM, Clean Architecture, Coordinator Pattern ------------ Selected Projects Maxxd Fitness app (App Store) Production iOS app built end to end: workout tracking, session-based video playback, subscription billing, PostHog analytics, and a modular Swift package architecture split across feature and core modules.AI powered meal scanning and tracking meal nutritions daily. ------------ How I Work I approach every project with an ownership mindset. I ask the right questions before writing a single line of code, communicate proactively, and deliver code that's clean, testable, and built to last. Modular architectures, clear naming, and future-proof patterns aren't extras they're how I work by default. Message me whether you're launching an MVP, scaling a production app, or need someone to own the iOS side of your product, let's build something users will love.

I don't just write code - I deliver solutions that drive real business results. I build native iOS apps and full-stack web products. Most of my work is iOS - Swift, SwiftUI, UIKit, but I've shipped a good number of React.js and Python projects as well, mostly SaaS platforms and web applications for startups and growing products. On the mobile side I've built apps from scratch and worked on complex existing codebases. The range is pretty wide: BLE and Bluetooth integrations for medical devices, VoIP clients with push notifications for incoming calls, food delivery apps with real-time map tracking, parental control systems with device-level Android controls, fintech apps with payment flows. I know the full release cycle well, architecture, development, QA, App Store submission, and post-launch support. On the web side I work with React.js on the frontend and Python on the backend. I've built property management platforms with KYC and payment integrations, fintech dashboards, marketplaces, and SaaS tools for various industries. REST APIs, third-party service integrations, role-based dashboards, that's standard territory for me. I've also worked on projects that combine both sides - a mobile app that's part of a larger web platform, or a web dashboard that controls what happens in the app. That kind of full-product thinking is probably where I add the most value, because I understand how all the pieces connect. Most of my projects run 3 to 12 months. I work well in async setups with clear requirements, and I'm used to collaborating directly with founders, product managers, and design teams. I give honest timelines, flag problems early, and won't disappear mid-project. Available for full projects, ongoing development, or focused scopes like a specific feature or integration.
