As a member of the R&D team in the Critical Embedded, I am working with RISC-V SoC PolarFire, FPGA, VHDL, HLS, C and C++ language.

Manaus, Amazonas, Brazil

As a member of the R&D Software and Embedded (FW and HW) team, I initiated the architecture of projects and led the team in the organization and task development. During this period, I developed security software for the home router to prevent vulnerabilities in the IoT network. Currently, I am developing a project in data acquisition for IoT devices for the industrial environment.

As a member of the R&D Embedded team, I initiated the architecture of firmware and led the team in the organization and tasks development.I developed firmware for a device that performs a covid test, calcium, and potassium. This development made it possible to obtain interesting results compared to conventional methods.

As a member of the software engineer team as a backend developer using FastAPI, database, microservice, message bus. I participated in the development of a new personal credit system.

As a member of the R&D team in the IoT group, I participated in developing the IoT platform using Embedded Linux, Yocto Project, Fog, and Cloud Computing (Azure) for energy management.

Member of the Detector Group, we develop a X-ray camera (Mobipix) with 2000 frames per second acquisition. I worked with PCB development using FPGA, Linux Kernel Driver development, Hardware with FPGA and Software applications.

As a member of TGM Beamline (Toroidal Grade Monochromator), I assisted internal and external researchers in the scientific instrumentation (HW and SW) to execute the experiments.𝐒𝐨𝐟𝐭𝐰𝐚𝐫𝐞: Python and PyQT to control and data acquisition for scientific instrumentation such as : light detector (photodiode, Photomultiplier and SiPM), low current measurement, step motor to position control, oscilloscope, etc.𝐇𝐚𝐫𝐝𝐰𝐚𝐫𝐞: A relevant project was a development of an instrument to low current measure (pA to mA) without changing scale using a logarithm amplifier.

As a member of the electronic group, I worked with digital and analog electronics.𝐇𝐚𝐫𝐝𝐰𝐚𝐫𝐞: 16-bits ADC and DAC, temperature measures, pulse counters, etc. Digital Logic using CPLD. PCB design using KICAD.𝐒𝐨𝐟𝐭𝐰𝐚𝐫𝐞: C language to simulate failure in hardware using a Single Board Computerin Embedded Linux.

In my Internship I worked for a teaching laboratory of RF and Communications assisting in preparation for experiments to electrical engineer course, such as: Monopole antenna, impedance matching in the transmission line, waveguides, AM modulation. Analysis of loss return (S11) e insertion loss (S12), frequency response in Hairpin filter and RF amplifier. Instruments, such as Spectrum Analyser and Signal Generator (3GHz).

As a member of the Optical laboratory, I developed some projects which led me to a master's degree. I worked with researchers about optical materials characterization with applications in opto-electronic. HW, SW and Instrumentation developing.Software and Hardware development for Optical experiments, such as: Spectrophotometer | Low current measurement (~ nA) | Lockin Amplifier | Photodetector | position control with Step motor | Current source control (0 to 50mA) | Photodetector. Automation and Data acquisition using LabVIEW software. PCB design using Kicad.

Software developer (User Interface) to Cluster control using CAN communication.
