Principal Software Developer

• Mar 2015 - Oct 2020

Designed embedded systems using AVR and ARM microcontrollers. Experience with serial communications (SPI, I2C, RS232, RS485, RS232, CAN), wired & wireless technologies (TCP/IP, UDP, Bluetooth, Ethernet, USB). Designed a financial management aid tool using VBA script. This script allows the manager to quickly lookup throughout thousands of registers and find any issues between sales and stock.

Researcher

• Sep 2018 - Jan 2020

I have developed a research to define the best control algorithm for keeping a nano satellite pointing towards Nadir with quaternion and using minimal energy consumption. The project includes an implementation of the Extended Kalman Filter which uses the direction from the Sun' and Earth's magnetic field to estimate the satellite's attitude. The project also include a controller's assessment, trying to identify the energy consumption.Also, I have worked on the C++ codes to embed the Kalman Filter in an ARM based microcontroller.

Developing a device to detect the spatial location of a lightning. The project uses three devices equped with a GPS to achieve a high time precision. Each device is placed in different areas to provide the triangulation required to estimate the lightning position. This project also included: - C/C++ and Assembly programming for embedded system - PCB Development. That PCB used a ISA slot to communicate with the computer Developing a device to detect the spatial location of a lightning.
