As a freelance engineer, I’ve collaborated with startups and established companies to bring over 20 products to market across the consumer, industrial, and medical sectors. I work across the full product lifecycle — from early specification and prototyping to manufacturing support and field testing. My expertise spans custom PCB design, RTOS-based and bare-metal firmware, and embedded Linux systems, using technologies like Altium, STM32, nRF52, ESP32, FreeRTOS, Zephyr, and more. I also support clients with architecture decisions, hardware/firmware co-design, and design optimization for cost, manufacturability, and reliability. Relevant Skills: ● Hardware design and PCB development (Expert) - Custom PCB design: Rigid, Flex and Rigid-flex technologies. - EDA tools: Altium Designer, OrCAD and KiCAD. - System-level design and project planning. - Schematic capture and library management. - Multilayer layout design following IPC and industry best practices. - High-speed digital, mixed-signal, RF/wireless, and power electronics design. - Interfaces: DDR, LVDS, HDMI, SATA, USB, Ethernet. - Circuitry: DC-DC converters, MCU/MPU/SoCs, ADCs/DACs, sensors, etc. - Familiar with PCBA manufacturing/assembly requirements and DFM/DFT rules. ● MCU Firmware programming (Advanced) - Languages: C, C++, Rust, ARM Assembly. - IDEs and tooling: Eclipse-based, VSCode, bare-metal toolchains, Make/CMake. - Firmware architectures: Bare-metal, RTOS, HAL/LL APIs. - RTOS: FreeRTOS, Zephyr (hands-on experience). - Ecosystems: STM32 (HAL/LL), Espressif (ESP-IDF), Nordic (nRF SDKs). - Version control: Git and SVN. - Familiarity with MISRA C/C++ standards - Architectures: ARM Cortex-M/R, Xtensa (ESP32). - Driver development: I2C, SPI, UART, ADC, PWM, external ASICs. - Protocols & stacks: BLE, LoRaWAN, HTTPS, MQTT. ● Embedded Linux development (Intermediate) - Linux for custom hardware platforms (MPUs). - Yocto Project: Linux distribution configuration and build. - Device tree and kernel driver development (sensors, ASICs, etc.).- Application development in C, C++, Python, Rust. - ARM Cortex-A architecture familiarity. ● FPGA & HDL Development (Intermediate) - FPGA/SoC development using Verilog, SystemVerilog, and VHDL. - Platforms: Xilinx Spartan-7, Zynq-7000; Intel (Altera) Cyclone, MAX series. - Custom IP design and hardware/software integration. - Familiarity with AXI/AMBA bus architectures. If you’re interested in working with me, I’m available via Freelancer and will always answer your questions or requests promptly. Thank you for your time and have a great day. weniger

I normaly design project following the IEE regulation, ISO standards, Uganda standards, IEC, total guidelines and international builders code. IET standards and i involve safety as the main axis of decision making. I worked at height, in ATEX zones,in oil & gas facilities, with power tools, in high traffic areas and i excuted projects with maximum safety precuations. In renewable energy fields, i have worked on a numerous number of mini grids, commerical and residential solar systems. This systems were grid-tied, hybrid and standalone sytem. In automation, i worked with deploying advanced automation (PLC, SCADA, DCS), optimizing system-wide energy efficiency through a secure network. in power system, i have designed multiple EV integration station as part of works in charging networks in East Africa. i have electrical installations and supervised the project to the commissioning stage. in this i was able to provide a technical support in lighting system, power factor improvement and system coordination. i have worked on cooling and heating systems, also pumping systems. My other experiences and certification are written in my CV Standards: IEE Wiring Regulations, IEC 60364, ISO 50001 (Energy Management), ISO/IEC 80079 (ATEX), TOTAL General Specifications, Uganda Standards, IBC. Areas: Power System Design & Coordination, EV Infrastructure, Solar PV Design (Mini-grid, Commercial, Residential), Lighting Design, Power Factor Correction, Pump & HVAC Systems. Tools/Software: (Solidworks, Altium 360, ETAP, Dialux, PVSyst, AutoCAD, EPLAN, SCADA/HMI platforms like WinCC, Ignition, PLC platforms like Siemens TIA Portal, Allen-Bradley). Standards: IEE Wiring Regulations, IEC 60364, ISO 50001 (Energy Management), ISO/IEC 80079 (ATEX), TOTAL General Specifications, Uganda Standards, IBC. I prefer working with Siemens, Schneider, Chint and ABBSquare,General Electric (GE),Rockwell Automation and backstoped inverter brands. weniger
