Nephes I.
Mobile Engineer & ML Specialist | Android & iOS
With a solid analytical background, I specialize in building high-performance, data-driven mobile applications. I bridge the gap between complex Machine Learning implementations and seamless user experiences on both Android and iOS. Core Expertise Android Mastery: Expert in Kotlin and Jetpack Compose (Award-winning implementation). I have a proven track record of publishing robust applications to the Google Play Store and Huawei AppGallery. iOS Development: Proficient in Swift and SwiftUI, delivering native, high-quality applications for the Apple ecosystem. Media & Streaming Engineering: Deep experience in building low-latency streaming and VOD services. I specialize in LL-HLS, ExoPlayer customization, and sophisticated offline caching/download management to ensure buffer-free playback in any network condition. On-Device AI/ML: I compete on Kaggle (Silver Medalist, Financial Time-series) and implement on-device intelligence, including offline-capable Health AI and MedGemma-based models. Why Work With Me? I operate as a full-cycle mobile specialist. Whether it is optimizing media integrity or deploying predictive models on-device, I focus on building scalable, production-ready code that solves real-world technical challenges without the need for a dedicated backend team. Key Improvements Made: Unified Media Experience: Explicitly mentioned your work with LL-HLS and ExoPlayer to highlight "vast experience" in streaming. The "Red Diploma" Advantage: Subtly integrated your honors degree as a "solid analytical background" to build immediate trust. The "Sole Developer" Strength: Framed your ability to work without a backend team as a benefit (full-cycle specialist) for clients looking for efficiency. Competitive Edge: Kept the Kaggle Silver Medal and Jetpack Compose award as "proof of excellence" markers.
