I specialize in Swift, SwiftUI, UIKit, modern concurrency, modular architecture, dependency injection, and end-to-end iOS product delivery. I have worked on major financial products, including a nationwide mobile banking application for the National Bank of Cambodia, a banking client for Sberbank, and a multi-chain non-custodial crypto wallet. I own features from requirements and architecture through implementation, testing, performance profiling, CI/CD, monetization, and App Store release. I also have experience mentoring engineers and improving engineering processes. More recently, I independently designed and shipped an AI-assisted iOS application with LLM-backed functionality, on-device speech processing, subscription monetization, and serverless infrastructure. I am available for remote contractor or EOR opportunities with US Eastern time overlap. ## Skills 29 capabilities[Actors](https://jobicy.com/talent/actors.md)[AVFoundation](https://jobicy.com/talent/avfoundation.md)[Banking Applications](https://jobicy.com/talent/banking-applications.md)[Bitcoin](https://jobicy.com/talent/bitcoin.md)[Blockchain](https://jobicy.com/talent/blockchain.md)[CI CD](https://jobicy.com/talent/ci-cd.md)[Code Review](https://jobicy.com/talent/code-review.md)[Combine](https://jobicy.com/talent/combine.md)[Core Data](https://jobicy.com/talent/core-data.md)[Core ML](https://jobicy.com/talent/core-ml.md)[Crypto Wallets](https://jobicy.com/talent/crypto-wallets.md)[Dependency Injection](https://jobicy.com/talent/dependency-injection.md)[Ethereum](https://jobicy.com/talent/ethereum.md)[EVM](https://jobicy.com/talent/evm.md)[Mentoring](https://jobicy.com/talent/mentoring.md)[MVVM](https://jobicy.com/talent/mvvm.md)[Objective C](https://jobicy.com/talent/objective-c.md)[Payment Systems](https://jobicy.com/talent/payment-systems.md)[Performance Profiling](https://jobicy.com/talent/performance-profiling.md)[Push Notifications](https://jobicy.com/talent/push-notifications.md)[Python](https://jobicy.com/talent/python.md)[REST APIs](https://jobicy.com/talent/rest-apis.md)[Solana](https://jobicy.com/talent/solana.md)[Swift](https://jobicy.com/talent/swift.md)[Swift Package Manager](https://jobicy.com/talent/swift-package-manager.md)[SwiftUI](https://jobicy.com/talent/swiftui.md)[UI Testing](https://jobicy.com/talent/ui-testing.md)[UIKit](https://jobicy.com/talent/uikit.md)[Unit Testing](https://jobicy.com/talent/unit-testing.md) ## Tech stack & tools Working toolkit ### Application Hosting [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/firebase/firebase-original.svg) Firebase](https://jobicy.com/talent?tool=firebase.md) ### Mobile [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/xcode/xcode-original.svg) Xcode](https://jobicy.com/talent?tool=xcode.md) ## Experience Career history ### Founder / iOS Engineer · Scriptmate (Line Learner) Jan 2026 – PresentFounded and independently shipped a SwiftUI iOS application for actors featuring script import, automatic cue detection, teleprompter functionality, self-tape recording, and AI-powered PDF script parsing.
