I help businesses build fast, scalable, and revenue-generating iOS apps — from idea to App Store success. I’m a Senior iOS Developer with 8+ years of experience building apps from scratch and improving existing ones. I’ve worked on products like GIF Maker, Edit UP, and Sticker Maker, with a strong focus on performance, smooth UI, and stable releases. Most of my recent work is around video processing and editing apps using AVFoundation, along with Metal/MetalPetal for high-performance rendering. I’ve also built PDF tools, VPN apps, and music streaming features, so I’m comfortable working across different types of products. Recently, I’ve started integrating on-device and API-based ML models into apps — including image/video processing, enhancement, and AI-driven features. I have experience working with Core ML, model conversion (e.g., from PyTorch/TensorFlow), and optimizing models for real-time performance on iOS. I usually work with Swift and sometimes Objective-C when needed. I use UIKit and SwiftUI depending on the project. I’ve also worked with CoreImage, CoreData, CoreAnimation, and PDFKit. For backend communication, I’ve used REST APIs and Firebase, and I have solid experience with In-App Purchases (subscriptions, consumables), push notifications, and app monetization. I follow structured architecture (MVVM + Coordinator) to keep projects clean and maintainable, and I use Fastlane for CI/CD when needed. I’ve also led small teams — handling code reviews, architecture decisions, and ensuring smooth delivery, especially in remote environments. Lately, I’ve been exploring AI integrations (like KlingAI, Pixverse) and learning more about medical/health-related apps. If you need someone who can take ownership and deliver high-quality results, I’m happy to help. Just send me a message.
