DO NOT APPLY IF YOU ARE: A web developer (React, Vue, Angular, etc.) A mobile developer (Flutter, React Native, SwiftUI) A blockchain / Web3 / NFT developer An agency or team Someone who says “I can learn LVGL” We are not interested in generalists. WHAT YOU WILL WORK ON Watch UI architecture LVGL / Qt render loop optimization Crown-driven scrolling & menus Gesture → UI feedback Haptic-synchronized interactions Power-aware UI behavior Always-on display strategies This role directly defines how the product feels. PAID TEST (REQUIRED) Before long-term work, you must complete a paid 1-week test task: LVGL (or Qt) demo on round display Smooth crown scrolling (no jitter) 60 Hz animation Haptic feedback on input UI sleep after inactivity Passing this test → long-term contract. TO APPLY — ANSWER THESE QUESTIONS Applications without answers will be rejected. Have you shipped an embedded UI on a round display? Which framework? How do you handle rotary encoder input without causing UI jitter? How do you reduce power consumption in an always-on watch UI? What causes frame drops in LVGL and how do you prevent them? What embedded products have you worked on? (links, photos, or videos preferred) RATE Hourly or fixed — negotiable for the right person Long-term opportunity if fit is strong FINAL NOTE This project is at a professional hardware startup level. We value: Ownership Craft Performance Simplicity If that excites you — apply.

With immense excitement, I offer my candidacy for the esteemed position of your Embedded UI Engineering Specialist. My skills align perfectly with your requirements - from deep-rooted experience in Embedded UI frameworks to proficiency in using LVGL, Qt, and Embedded Linux. Additionally, I am well-versed in working with round displays (including AMOLED and TFT), physical inputs, and keen on delivering power-aware UI behavior which I believe is vital for AI smartwatches like yours. Having dealt with various embedded systems before, including wearables, I understand the intricate balance between performance and power consumption. Frame drops can hamper user experience, hence I am deeply aware of what causes them in LVGL and how to eliminate them for smoother functioning. I have also worked on many watch UI architecture designs that maximized haptic-synchronized interactions and demonstrated well-planned always-on display strategies. To ensure a long-term working relationship with my clients, I primarily focus on providing production-grade, scalable solutions that stand the test of time – just as your high-end smartwatch is designed to do. Apart from technical proficiency, my evidently clear communication style and willingness to take ownership of projects would add immense value that goes beyond coding. Let's hop on a call to further explore how our paths can intersect for a successful venture ahead!

Hello, I’ve shipped an embedded UI on a round AMOLED display using LVGL for a healthcare wearable focused on continuous monitoring. In that project, optimizing the render loop and managing partial redraws were key to smooth always-on operation. For rotary encoder input without jitter, I implement software debouncing combined with frame-synced input polling, ensuring scrolling stays fluid without overshoot. Power consumption drops by leveraging partial redraws, aggressive frame pacing, and strategically dimming the display during inactivity while maintaining instant wake. Frame drops in LVGL are usually caused by blocking calls or redraws of entire screen regions; I mitigate this by carefully planning UI layers, minimizing full screen refreshes, and offloading heavy computations from the render thread. I’ve worked on multiple embedded Linux devices with Yocto builds, including a rugged medical device with physical buttons and rotary inputs. I can share videos of the UI in action if needed. I’m keen to take the paid test and demonstrate how I can deliver smooth, power-aware UI performance for your smartwatch. Ready to get started as soon as you say go. Best regards.
