We are looking for someone with skills in QT and Embedded ARM Linux.

@AwaisChaudhry

Hello, I understand you need to modify and extend an existing Qt/C++ app for embedded ARM Linux, with work near the hardware such as device tree and V4L2 style drivers. I will review the current code, outline a focused plan, implement clean Qt interfaces, ensure robust interaction with the kernel and drivers, and provide solid tests on your target board. I will work closely with your small team, deliver incremental milestones, and keep changes well documented for easy future maintenance. What follows are key questions to align on scope and risks: What is the target ARM board and hardware specs? What is the current status of the Qt app and which modules will be extended first? Which driver interfaces need changes (V4L2, I2C, GPIO) and what are the acceptance criteria? Do you have a device tree source, or should I start from an existing DTS and modify it? What is your preferred build system (qmake, CMake) and the CI workflow? Are there any performance constraints (memory, CPU, power) I should keep in mind? What is your test strategy (unit tests, hardware-in-the-loop, remote debugging)? Are there coding standards, review processes, or specific tooling I should follow? What timeline or milestones do you envision for initial delivery and ongoing work? What is the single most important milestone you want delivered in the first sprint? Best regards,

Hi, I have strong experience working with C++/Qt applications on embedded Linux systems, including ARM-based environments where stability and hardware interaction are critical. I’ve handled low-level debugging, driver interaction, and performance tuning close to the kernel, including working with device interfaces and camera pipelines (V4L2-style workflows). For this project, I can jump into your existing Qt app, extend and stabilize it on ARM Linux, and handle device-level integration—whether that’s debugging driver issues, adjusting device tree configurations, or ensuring smooth communication between the UI layer and underlying hardware components. You can expect clear communication, reliable ongoing support, and someone comfortable working close to the hardware without needing hand-holding. Let’s get started. Best regards, Juan

@adisonw

Dear Sir, I am thrilled to bid your project. I can work on modifying and extending your existing Qt/C++ application, ensuring stable improvements without breaking current functionality. I have solid experience working with embedded Linux systems on ARM platforms, focusing on real-world device constraints and performance. I am also comfortable working close to hardware layers, including device tree configuration and camera integration through V4L2 or similar kernel interfaces. This fits well with ongoing remote collaboration, and I’m used to working in small technical teams where clean communication and iterative development matter. I keep changes structured, test-driven, and aligned with production stability rather than experimental redesigns. Before we proceed, what ARM platform and camera stack are you currently using (kernel version + Qt version), so I can align my approach with your exact hardware environment? Sincerely, Adison.

@TechWagger2026

Hello, I have strong hands on experience in exactly this layer of low level software work and would be glad to support your team. With 14 plus years of C plus plus systems development and Linux based engineering, I have worked on Qt desktop and embedded interfaces, ARM Linux deployments, board level configuration, hardware communication modules, and kernel adjacent debugging where application behavior depends heavily on device integration stability. I am comfortable modifying and extending existing Qt applications, optimizing signal and slot logic, UI controls, hardware event handling, and performance on ARM targets. On the embedded side, I have practical experience with Linux device tree adjustments, peripheral bring up, serial and camera interface configuration, V4L2 based device communication, driver level troubleshooting, and working directly with kernel interfaces when hardware abstraction layers need correction. I understand the discipline required when software sits close to physical devices and cannot rely on high level assumptions. I am available for ongoing remote collaboration, direct technical communication, and stable long term contribution with your small engineering team. Software expertise: Qt, C plus plus, ARM Linux, Embedded Linux, Device Tree, V4L2, Driver Integration, Kernel Interface Debugging. Regards Arun
