About

Transforming Your Ideas into Reliable Hardware & Microelectronics

Hello! I’m an Electrical and Computer Engineer with 3 years of experience helping clients build custom PCBs and robust embedded firmware. I hold a degree in Microelectronics from Addis Ababa University (graduated with Great Distinction), combining strong academic fundamentals with practical hardware engineering.

How I Can Help You:

Advanced PCB Design: Complete schematic capture, multi-layer routing, high density pcb layouts, HF (high-frequency) considerations, component sourcing, and Gerber/BOM generation with full DFM (Design for Manufacturing) compliance using Altium Designer, KiCad, or EasyEDA.

Embedded Programming: Efficient C/C++ firmware development for STM32, ESP32, MSP430, ATtiny, and Raspberry Pi platforms.

IoT & Connectivity: Low-power sensor integration and seamless communication via LTE, CAN bus, I²C, SPI, and UART.

From digital utility meters to remote telemetry systems, I deliver high-quality, production-ready designs built to work smoothly right out of the box.

Reach out with your schematic or project brief—I’m ready to help you build your next hardware project!
