Cir Design / Embedded SW / Manf / ESP32 / AWS IOT

Over 25+ years of engineering experience. I'm particularly good at prototype development and light manufacturing. I am an American -- educated in Computer Engineering from a US based ABET-accredited University. I am located in Asia for a competitive advantage. I work with the ESP-IDF. I'm also competent with PICF18 processors but I haven't used them in several years (100% into the ESP32 now). I also have a history in Windows Application development, but I lean today towards dotNet MAUI for multi-cross platform app development. I have been developing with the Esp32 since January of 2019 (4 years now). I normally write all my Esp32 applications in C++ and use the Espressif framework libraries. I do not care for Arduino. Arduino libraries are becoming irresponsibly complex under the covers. These libraries make some features easy to use up-front, but they are increasingly harder to maintain and nearly impossible to understand in code. You may be up and running quickly, but then discover that you can't get the last 5% of the features you want. One of the things that I can do I tear apart these libraries and simplify them for your intended project target. In essence, we are reducing complexity and bringing your project back down to the normal ESP-IDF framework. When you are good at understanding C/C++ and the standard IDF library, you don't need or want Arduino to bloat your project and inject source code that you can't maintain. If you want to get to know who your contractor (me) -- I always suggest to any client that they should put me in front of an expert for a technical interview. I am happy to take a video conference call and handle probing questions from a professor in Computer Science/Engineering, Electrical Engineering, or Physics. Anyone one of these scholars should be able to judge my background and experience easily. Feel free to have a look at some of my work here. Please reach out to me if you have any questions.

I normally make all my own boards, but sometimes I do buy development kits.

I'm close to China, so it is very easy for me to get new releases of China made products within about a week.

You just can't get a project done well without a strong roadmap to help you squeeze out the inconsistencies.   Here are some samples of how I document the work so I can review it and deliver it to a client.

Some of these documents directly reflect my work with the AWS IOT SDK.
Documentation.... the road map to success!
