I am an Electronics and Embedded Systems Engineer specializing in firmware development, PCB design, battery management systems (BMS), and hardware integration. I work with STM32 and other microcontroller-based systems, developing reliable embedded firmware in C/C++ and integrating sensors, communication interfaces, and peripheral devices using SPI, I2C, UART, CAN, ADC, PWM, DMA, and interrupts. My experience includes schematic and PCB development, board bring-up, hardware debugging, sensor integration, power and battery-related electronics, BMS development, and communication between embedded devices. I can support projects from the initial hardware architecture and component selection through firmware development, testing, debugging, and final system integration. I am comfortable working with real-world embedded systems where hardware and software must be debugged together. I focus on clean firmware architecture, reliable communication, accurate sensor data acquisition, and practical solutions that can be deployed on actual hardware. I can help with: • Embedded C/C++ firmware development • STM32 firmware and peripheral configuration • PCB schematic and board design • Battery Management Systems (BMS) • SPI, I2C, UART, CAN and USB communication • Sensor and actuator integration • GPS, IMU, pressure and environmental sensors • ADC, PWM, timers, DMA and interrupt-based systems • Hardware bring-up and debugging • Existing firmware troubleshooting and optimization • Prototype development and system integration Whether you need to develop a new embedded product, debug an existing board, integrate sensors, or improve firmware reliability, I can provide support from prototype through final implementation.

Mechanical design and CAD specialist with a Mechatronics Engineering background and over 4 years of hands-on experience in SolidWorks, 3D printing, and prototyping. Certified by Dassault Systèmes (CSWA, Additive Manufacturing, Sustainability). I’ve led interdisciplinary R&D projects, participated on Bolivia’s first CubeSat and award-winning NASA HERC team, and developed functional parts for clients and research. Passionate about precision modeling, real-world engineering impact, and bringing complex ideas to life through CAD and prototyping.

Mechanical design engineer with 5+ years of R&D experience taking products from concept to mass production. At aweXome Ray (2020-2025), I was responsible for the mechanical design of three filterless air purification modules: - M50: module for air handling units (AHU) - M25: module for energy recovery ventilators (ERV), installed in schools - M02: residential module What I can help you with: - 3D modeling and 2D production drawings (SolidWorks, AutoCAD) - Sheet-metal enclosure and plastic part design - Design for manufacturing (DFM) and cost reduction - Airflow analysis with SolidWorks Flow Simulation - BOM preparation and turning prototypes into production-ready designs - Communication with sheet-metal, mold and injection-molding vendors I have also designed mechanisms, such as a rotary workpiece feeder driven by a planetary gear set, built as a working prototype. Based in South Korea (KST). Share your sketch, model or requirements, and I will suggest a practical path to a manufacturable design.
