Monitor I3 @ A3E Ingenieros

I'm Jayr Gil Galicia Jiménez, a Full Stack developer specialized in building robust end-to-end systems, from backend APIs to real-time interfaces. I work primarily with Java (Spring Boot) and React, integrating relational and non-relational databases depending on the project's needs.

I'm particularly interested in software for industrial and regulated sectors, where data accuracy and integration with real hardware (meters, protocols like Modbus TCP) matter just as much as the user experience. I'm currently developing Monitor I3, an electrical variable monitoring platform for regulatory compliance, and collaborating on quality management systems that digitize internal processes.

Beyond my work at A3E Ingenieros, I'm co-founder of NGC Software Solutions, where I deliver custom software to real clients, from the initial conversation through to delivery.
