ESP32 LoRa Firmware and UI Development

@shadabkhan92

With my team, your project is in safe hands - we have a rich history of delivering full-stack machine-to-machine systems that blend both firmware and UI aspects. Not only do we have extensive experience with ESP32 development, Embedded C/C++, FreeRTOS, LoRa, and industrial embedded systems, but we also specialize in TFT display UI development and graphic libraries for embedded systems like TFT_eSPI and LVGL. This means we can adeptly tackle the two major portions of your project: Firmware Optimization and Remote UI Development. One crucial aspect of this undertaking is the UX design for the handheld remote. We understand that a smooth, clean interface is essential for easy navigation and accessibility, especially in an industrial environment. Our UX/UI design expertise will enable us to create an aesthetic interface while ensuring it remains lightweight for your ESP32 device's memory usage constraint. Additionally, our familiarity with Git version control ensures an organized codebase for easier maintenance and modularity.

Your project is exactly the kind of work I enjoy most—taking a working system and making it cleaner, faster, and genuinely pleasant to use. I can see you've already done the heavy lifting on the LoRa core, and I'd love to help you polish the rest. Here's what I bring to this: → I've built several ESP32-based industrial control interfaces, including a custom air quality monitor with a full TFT UI and MQTT connectivity, so I know how to keep things responsive on constrained hardware. → I've worked extensively with ESP-IDF and FreeRTOS, and I'm comfortable refactoring existing code into clean, modular structures without breaking communication reliability. → I can handle the full stack—firmware optimization, UI design with TFT_eSPI or LVGL, and even PCB-level considerations if you need input on the hardware side. → I'm available to start immediately and can have an initial code review and UI mockup ready within the 5 days to ensure we're aligned. For this scope, the cost would be 4500, which includes the firmware refactor, the complete UI implementation, and thorough documentation. Happy to walk you through my approach and past work on a chat.
