$25-50 USD / hour

I have an existing application running under nuttx on an STM32F107 which needs to be reviewed, reworked, and some bugs fixed. Please explain why you are the best for this job, what experience you have with nuttx and STM32. I will then share (confidential) some further requirements and we can agree on fixed prices, for now, please quote your hourly rate. One of the requirements will be, for example, to fix issues with the usb driver and to move from a custom driver to a standard CDC driver provided by nuttx.

I have been working with STM32 constantly for over 10 years now and I have been using NuttX since 2012. I've used this RTOS is projects working in industrial environment (up to 30 kloc of my own application), where the application is working 24/7 for months with no downtime or resets, on remote locations where maintenance possibilities are limited. In my work I have contributed some minor improvements to the NuttX repository, mainly related to the bugs that I've found and support for some STM32 chips which were then not supported by NuttX. I'm also the author of a C++ RTOS for microcontrollers - distortos. I consider myself experienced with multithreaded applications and designing software architecture. This experience allows me to spot problematic constructs, which usually lead to severe issues (like race conditions or deadlocks).

I ported NuttX to STM32 and we also write high-performance self-signed (no extra cert is needed from Microsoft side) USB drivers with cross-platform Windows, MAC, Linux support.

Dear, Hope you are doing well. I am writing on behalf of Everest Consulting - we are a tech firm from Sarajevo BiH, specialized in software and hardware development. My team and I reviewed the project specifics and we believe that we can help you with this engagement. We analyzed the references and feel confident with the tasks as our prior work overlaps quite well this project. We believe to be the best fit for this project as we have a team of engineers that can work together on just tasks and provide timely results. Also, we do have some questions in regards to functional and electrical requirements of the application - I suggest to set up a meeting to discuss this. In the next step we can provide you with a comprehensive list of our previous work. For now, please refer to our portfolio on our Freelancer page. Please let us know if you have any questions. Best, Alen Degirmendzic
