Have an idea for a touchscreen product but don't know how to bring it to life? Or struggling with an embedded display that isn't performing as expected? I help startups, businesses, and engineering teams turn their ideas into working embedded products; from hardware selection and firmware development to beautiful, responsive touchscreen interfaces. Whether you're starting from scratch, improving an existing prototype, or dealing with a challenging technical issue, I can help you move forward with a reliable, practical solution. ### How I Can Help You 🚀 From Idea to Working Prototype - Turn your product concept into a functional embedded system - Select the right MCU/MPU, display, and hardware architecture - Develop firmware, application logic, and touchscreen interfaces - Integrate sensors, connectivity, and external peripherals - Build prototypes ready for testing, demonstration, and further product development 🖥️ Professional Embedded GUI & HMI Development - Develop modern touchscreen interfaces using LVGL, TouchGFX, and Qt/QML - Build applications for STM32, ESP32, and Raspberry Pi - Integrate SPI, QSPI, RGB/LTDC, and MIPI-DSI displays - Optimize animations, rendering performance, and memory usage - Create intuitive interfaces that run smoothly on real hardware 🔧 Debug, Improve & Complete Existing Projects - Fix display glitches, crashes, touchscreen issues, and unstable firmware - Diagnose performance bottlenecks and hardware integration problems - Take over unfinished projects and bring them to completion - Refactor and optimize existing embedded applications - Improve system stability, responsiveness, and maintainability ### Experience That Goes Beyond the Screen I've worked on automotive dashboards, instrument clusters, smart thermostats, industrial HMIs, IoT devices, audio products, and connected touchscreen systems. I don't just design interfaces. I understand how the display, microcontroller, firmware, communication protocols, and application logic must work together to deliver a dependable product. ### Technologies LVGL | TouchGFX | Qt/QML | STM32 | ESP32 | Raspberry Pi | C/C++ | FreeRTOS | Embedded Linux | Wi-Fi | BLE | MQTT | SPI | QSPI | I2C | UART | CAN | MIPI-DSI | RGB/LTDC ### Let's Bring Your Project to Life Whether you have a new product idea, an existing prototype, or a technical challenge holding your project back, tell me what you're building and where you need help. I'll help you find a practical path from concept to a working embedded solution.
