Hello,
I'm just starting out in this field of freelancer, and for this reason the cost offered is the least since I have no references.
For your peace of mind, I am an electronic engineer and I have experience in circuit design.
I think it could be of great help for your project, I have great knowledge in programming microcontrollers, especially PICs, I have done courses on microchip programming. I have worked with:
Pic 12
Pic 16
Pic 18
Pic 24
dsPic
I have also done PCB design courses, and I use different softwares for your comfort, including proteus, and simulation in it.
I am already at your disposal
regards
