M Hamzah A.

I build Qt/QML applications for desktop systems, connected devices, and embedded Linux products. I connect user interfaces with hardware, REST APIs, and databases to bring device controls, live data, and business workflows into one application. Whether you need a new Qt interface, embedded software development, or IoT integration, I can connect your application with devices, web services, and databases. My experience includes vehicle clusters and infotainment systems, medical device interfaces, industrial HMIs, and Python-based desktop applications. At MRS Technologies, I worked on an i.MX6-based platform, including Qt/QML interfaces, Bluetooth integration using BlueZ and D-Bus, U-Boot customization, and Mender OTA integration. I can help with: • Qt/QML application development: interfaces using C++ or Python, application logic, hardware communication, debugging, optimization, and deployment. • IoT development and integration: connected device dashboards, MQTT and Bluetooth communication, REST API integration, and database storage and retrieval. I can also develop supporting REST APIs and database functionality when your project needs them. • Embedded systems development and integration: application and device software, hardware communication, and peripheral integration using CAN, UART, I2C, SPI, MQTT, TCP/IP, and Bluetooth/BLE. • Existing product improvements: resolving application issues, improving UI responsiveness, and integrating new features into an established codebase. • Linux customization and Yocto: custom Linux images, board configuration, kernel and U-Boot customization, and device driver integration. My platform experience includes NXP i.MX, Raspberry Pi, and Texas Instruments boards. I also work with PyQt and PySide for desktop applications and engineering tools. As co-founder and CTO of Stackware, I remain involved in development while helping clients make practical technical decisions. My Upwork record includes 100% Job Success and four completed contracts with five-star ratings. Tell me about your target hardware, current software, and what you need to build or fix. I can help define a practical scope and delivery plan.
