Andre Belem

Recently, I started a career transition to Electronic Engineering. My first project is an end-to-end solution for Telemetry. The web server was brought online on May 15, 2026. We will use MQTT with a MySQL database on the back-end side.

On the client side, the hardware chosen as ESP32. I'm a Electrical Engineer with expertise in Telecommunications and Networks, with over ten years of experience in high-availability networks for leading telecom operators. Skilled in network expansion, contingency, and planning using BGP, MPLS, IS-IS, IPv4/IPv6.

Deep knowledge of data center infrastructure, peering, and international connectivity. Proficient in automation and tool development for operational analysis and KPI monitoring with Linux, Python, PHP, Bash, and MySQL. Led deployment projects, equipment implementation, and strategic capacity planning.

Analytical and automation-focused, committed to resiliency and operational efficiency.
