About

I am an Embedded Developer and Electronics Engineer with over 14 years of experience in Electronics Hardware Design, Hardware Development, and Hardware Engineering. I have experience developing reliable hardware and software for complex systems, from interactive technologies for escape rooms to industrial climate control systems, smart dispenser controllers and turnstiles. Throughout my career, as a Senior Hardware Engineer and Hardware Designer, I have successfully led the development of electronics for a high-tech water cooler dispenser, managing a distributed system of three controllers communicating via RS-485, integrating touch controls, proximity sensors, and IoT connectivity for remote telemetry. At PROSOFT, I fully architected the electronics for an intelligent turnstile system, including a BLDC motor driver with PID control, a synchronized IR-barrier array with 16ms response time, and automated test benches. I also designed a semi-automatic thermal-humidity chamber certification system, which streamlined a critical industrial process. My engineering approach is holistic: I can define the technical specifications, design the schematic, lay out the PCB, write the firmware for STM32 microcontrollers in C/C++, handle Software Development, design the enclosure using 3D modeling and industrial design principles, 3D print a prototype, and prepare everything for mass production. Core competencies and technologies: • Hardware: Full-cycle electronics design (Schematic to PCB), component selection, 4-layer PCB layout in KiCAD/TopoR. • Firmware & Software: Extensive experience programming STM32 (STM32CubeIDE) in C/C++ and C++ for embedded systems. • Interfaces & Protocols: I2C, I2S, SPI, UART, RS-422, RS-485, USB, SDIO, Wiegand. • Specialized Systems: BLDC motor control (PID, obstacle detection), IR-barrier arrays, IoT (Wi-Fi/GSM telemetry). • Tools & Equipment: Oscilloscopes, signal generators, RLC meters, 3D printing (SolidWorks, FDM), reflow/Hot-air soldering (including QFN/LQFP). I am actively seeking new opportunities to apply my full-stack hardware and firmware expertise. Let's connect to discuss how I can help bring your embedded product to life.
