Juan Guarnizo
@juanguarnizo
Hardware developer designing ultra-low-power embedded systems, PCBs, and solar-powered power management solutions.
ColombiaWhat I'm looking for
I’ve spent 10+ years across the analysis, design, integration, development, testing, and implementation of embedded software systems, plus several years in PCB design, electronic circuit calculations, and power management.
At Boliemacom SAS, I lead R&D&I efforts, standardize processes, and oversee the full hardware lifecycle from design and validation to QA, while optimizing sourcing with local and international suppliers. I’ve also built end-to-end PCBs (including layout, fabrication, and negotiation with Chinese suppliers) and delivered licensing workflows like a Docker + Laravel portal and a Python GUI license client for Linux/Windows.
Previously at Insitel SA, I deployed data pipelines on Debian for weather stations and early warning systems, built ultra-low-power sensing hardware for water pressure via 4G, and used MQTT middleware plus Python-based visualization. I’ve also created Raspberry Pi-based monitoring with Splunk integration, and at Eagle Commercial SA I developed a 360 video streaming security system on Raspberry Pi Zero.
