Sobre mí
Electronic engineer and electronic technician, experienced on development of automated equipment, embedded process control and system integration, having worked on R&D of projects for the most varied applications such as: Vehicles, Phones, Image, Medical, Chemical and Energy.

Worked on design of electronic products in various knowledge areas:
> Hardware layout with some CADs ( Altium Designer, Mentor Graphics, P-CAD, Eagle, Protel99 )
> Software program on high level languages and toolset ( QT, JAVA, C++Builder, Delphi, Android )
> Firmware in ASM or C language for many cores ( ARM7, PSoC, dsPIC, 51, MSP430, Z84, AVR )
> Automation: PLC IEC 61131-3 standard ST and IL languages ( Beckhoff )
> FPGA design using VHDL hardware description language ( XILINX )

Final graduation engineering project based on ASIC design ( Edge/Cadence ) by schematic capture, developed an integrated circuit ( IC ) on courses "Microelectronic 1-2" on which applied more than 300 standard cells from ES2 library.

With an extensive history of designs done either as freelancer or as employee.

Giving part time support as Moderator for 2 forums, one in English and other in Portuguese, both related to the electronic scope.
