Profile Description

Hello, I’m OB, an experienced iOS Developer with a passion for engineering stable, high-performance mobile applications. I specialize in managing the end-to-end mobile lifecycle—from modernizing legacy codebases and building reusable libraries to overseeing internal testing, release pipelines, and App Store distribution.

I bridge the gap between technical excellence and business strategy. In my recent roles, I have successfully reduced app crash frequencies by 30% through proactive monitoring and increased business revenue by 15% by integrating cross-platform marketing tools and optimizing user flows.

Whether I am collaborating with designers to bring UI/UX mockups to life, writing comprehensive technical documentation for mobile teams, or implementing rigorous unit and automated UI testing, my goal is always the same: to deliver clean, testable, and highly reliable software that users love.

1. Full-Lifecycle iOS Development: Expertise in managing everything from architectural design and feature implementation to release pipelines and App Store distribution.
2. Performance & Stability: Proven ability to diagnose bottlenecks using Firebase Crashlytics, implement multi-threading techniques, and modernize legacy codebases.
3. Quality Assurance & Testing: Strong advocate for code quality, experienced in conducting rigorous code reviews, writing unit test suites, and developing automated UI tests using Appium and Ruby.
4. Cross-Functional Collaboration: Skilled in translating QA feedback, design mockups, and business requirements into seamless mobile experiences while maintaining clear technical documentation for iOS and Android teams.
5. Custom Tooling & Libraries: Experience developing reusable CocoaPods libraries (e.g., document scanners, photo viewers) to streamline team workflows and accelerate development.
