Marc James Beltran

Electronics Engineer | Embedded Systems and IoT

An electronics engineer specializing in embedded systems and IoT solutions, with hands-on experience in microcontroller programming, hardware and software design, AI model development, and cloud-integrated applications.

I have worked on research and development projects where I optimized workflows, developed prototypes, and delivered scalable solutions aligned with organizational objectives. I have published open-source Arduino libraries through my GitHub account, contributing to the developer community. I was part of the Batangas State University team that won the Champion University Category at the 2022 Engineering Innovation Challenge in Singapore for developing AI-Quaponics 360, an AI-powered intelligent aquaponics system.
