Summary
👤
Senior🎓
Top SchoolGaëtan H is a senior Android developer based in Marseille with over a decade of hands-on experience modernizing mobile apps for startups and global companies like Facebook and American Express. He specializes in Kotlin, Jetpack Compose, and robust architecture migrations (MVP → MVVM/MVVI), and has a track record of improving performance, accessibility, and CI/CD workflows. At Facebook he automated the Java-to-Kotlin migration of the popular Litho UI framework and contributed developer-focused fixes and sample enhancements to the open-source repo. He also led Android teams, built SDKs and white-label solutions, and boosted user conversion through localized onboarding and A/B testing. Comfortable across fullstack touches (Scala backend work, CI automation), he blends product-minded engineering with practical developer experience improvements. Pragmatic and curious, he often surfaces behind-the-scenes optimizations—like compile-time Moshi adapters and dependency-scope fixes—that yield measurable UX and performance gains.
