Hi, I'm Ibrahim. I'm a Computer Engineering student finishing in 2027 who works with Arduino/firmware, KiCad PCB layout, and electronic prototyping. I help clients turn a breadboard, hand sketch, or rough schematic into a clean, manufacturing-ready PCB — with component selection, footprint assignment, design rule checks, and full export packages (Gerbers, NC drill files, pick-and-place, and BOM) when the job calls for it. On the firmware side, I write modular Arduino C/C++ code for sensors and modules (HC-SR04, HuskyLens AI vision, motor drivers such as the L298N), displays (OLED SSD1306, 16x2 I2C LCD), and communication buses (I2C, SPI, UART, PWM). I'm also taking a DSP course and learning LabVIEW, so I'm building that path into my work as well. My recent projects include an Arduino + HuskyLens automated block sorter and a pipeline pig detector PCB I laid out in KiCad, plus PCB layout and component selection work done for a university instructor. I communicate clearly, keep documentation simple, and aim to deliver organized, usable files the first time.

CHILE: I have started my work experience as a Junior level Android Developer in a job that required image editing and interface design for phones. I also worked on low-level programming (C) for microcontrollers. Communication protocols MODBUS, UART, I2C, ISCP, MIDI. When I gained more experience, I decided to specialize in the EgleCAD program for PCB design for industry and IoT. I have used the EagleCAD program for more than 2 years and I have created libraries of devices and chips that were not found in the standard libraries. I also design from the datasheet taking into consideration the different measurements that the manufacturer has. CAM Gerber DXF BOM PLC PnP files are common in PCB design. I can learn to use other software for projection. Then I learned how to use EasyEDA for fast prototyping PCB designs. To test the PCBs I used a digital oscilloscope. I founded a hardware development company (Gea Tecnologia) to be able to work together with universities. The company worked closely with a team of bioengineers from Adolfo Ibañes University and a private company called DigitalHealt. The project is called Grace and currently has a US patent. The company grew and we had requests for very specific things that required little development time. One of them was to create a device that provided a wireless network to provide Internet connection in extreme places in Chile. They had to be energetically autonomous modules and cheap to build. The company (Statknows) was very happy with the result.(LoRa). ITALY: I applied to Embedded Solutions SRL company which is specialized in the production and manufacturing of electronic boards. Located in Misinto. Here I learned many concepts of production and test techniques (collaudo) for pcbs. A very serious company where every aspect of the design is guaranteed 100% even aesthetically.
