HOAI NAM D.
Wear OS & Smartwatch UI/UX Designer | WFF & Wearable App Developer
Hi , I'm Nam, I am a Wearable UI/UX & Wearable Systems Specialist who bridges the gap between high-end graphic design, native watch face coding, and hardware integration. Unlike traditional designers who only create static image mockups in Figma, I build fully functional, interactive watch faces and custom widget ecosystems across all major smartwatch platforms. 1. End-to-End Smartwatch & Watch Face Development: Supported Platforms: Wear OS, Garmin, Huawei, Amazfit, Apple Watch, Amazfit.., and other freeRTOS smartwatch. Beyond Graphic Design: I don't just design the visuals; I actively write native code (Kotlin, XML, Monkey C, Watch Face Format - WFF) to build complex custom data types, complications, and widgets that are not available out-of-the-box. Performance & Battery: Every watch face is fully optimized for smooth rendering, Always-On Display (AOD), and low battery consumption. 2. Companion Apps & Wearable IoT Solutions Wearable + Mobile Companion Ecosystems: Experienced in creating seamless combos featuring a Watch Face Dashboard + Connected Mobile App. Utility & Pager Systems: Specialized in building IoT notifications, real-time alert dashboards, and clinical/pager-style monitoring applications directly on smartwatches. 3. Embedded Display & Hardware Integration (IoT) ESP32 LED Matrix / Smart Clocks: Successfully designed and built an advanced ESP32-S3 (N16R8) smart display system using Arduino IDE, implementing single-buffer and DMA PSRAM architectures. Firmware Features: Built-in clockface editor directly in firmware, custom widgets, mini-games, AI chatbot players, and ambient standby desk-clock applications for Android. 4. AI Visuals & 2D Graphic Design AI Workflow Integration: Advanced visual production and rapid concept development using Stable Diffusion, ComfyUI, Flux, and Wan Video. Design & Editing Suite: Expert command of Figma, Adobe Illustrator, Photoshop, DaVinci Resolve, and CapCut. Whether you need a commercial watch face with custom Monkey C/Kotlin logic, an IoT health/pager dashboard for Wear OS, or a custom hardware display system, I deliver complete end-to-end solutions from concept to functional code. Let’s connect and bring your wearable project to life!
