Summary
👤
Senior🎓
Top SchoolOleksandr Bretsko is an iOS developer with over 11 years in software engineering and more than two years of commercial iOS experience, fluent in Swift and familiar with Objective-C, C/C++, and Python. He builds production-ready apps and frameworks using VIPER/MVVM, CoreData, MapKit, AVFoundation and multithreading, and has hands-on experience submitting apps to the App Store and managing CocoaPods and Git workflows. Beyond apps, he designs modular Swift packages—most notably a multi-module NLU/NLP spell-checking framework that parses dates, currencies and complex text structures—which sharpened his SOLID and clean-code practices. He has practical ML and NLP knowledge (NumPy, Pandas, TensorFlow, Keras, SpaCy) and has implemented Alexa skills with AWS Lambda, showing a taste for cross-domain integration. His background includes developing a medical device simulator and refactoring large projects, evidencing both greenfield and maintenance strengths. Based in Ukraine, he pairs strong engineering fundamentals with a track record of independent pet projects that surface non-obvious language and parsing expertise in Swift.
