Portfolio

I have been working in many industries including complex systems, large scale consumer electronics, satellite modules, industrial programable logic controllers (PLCs) and its expansion modules, telemetry and IoT acquisition systems using cellular mobile network, GPS trackers for trucks, handheld battery powered devices, load monitoring system for offshore cranes, medical equipment, and banking ATMs.  I'm familiar with technologies such as Wi-Fi, GSM/3G/4G, GPS, Bluetooth, RFID, RS-232, RS-485, I2C, SPI, CAN, USB, PCIe, SpaceWire, Ethernet, EtherCAT, common industry microcontrollers and processors, FPGAs, DDR memories, switched mode power supplies and battery chargers. 

​

Skills to deliver end-to-end development:

​

• Specification of design requirements and hardware architecture definition; 

• Schematic capture and multilayer PCB layout - Altium/Pads/Eagle;

• PCB design respecting mechanical, RF, high speed and EMI/EMC constraints.

• Design for Manufacture (DfM), Design for Test (DfT), and Design for Reliability (DfR);

• Integration between Electronics-CAD (E-CAD) and Mechanical-CAD (M-CAD) - Solidworks;

• Analog and digital simulation - SPICE, Modelsim;

• Firmware programming for embedded systems - C/C++, FreeRTOS;

• FPGA development - VHDL;

• Automated test scripts - Python;

• Prototype assembly and troubleshooting;

• Product tests for performance, EMI/EMC, ESD, surge, vibration, temperature and humidity; 

• High quality design documentation.
