Hola,
I’m an Electronic Engineer and I have almost 30 years of experience in software development mainly with C and C++, but also with Java, Python, Perl, etc over unix or windows mainly in backend and middleware, distributed or real time (qnx, freeRtos, etc) and some frontend experience.
I think I could help you.
BTW I think you talk Spanish, but I'm not sure (it's my native tongue)
saludos
