Hi, I’m Diego, a Network and Systems Engineer based in Paris with over 5 years of experience in designing, deploying, and managing reliable and scalable systems.
I specialize in observability, creating tools and workflows with platforms like Grafana and Prometheus to provide teams with actionable insights. My expertise also includes automation ensuring systems operate efficiently and reliably.
Led the engineering development and deployment of STIR/SHAKEN for a telecom operator in France. I was responsible for an eight-month development process using Kamailio to update the existing call flow, ensuring proper communication with the PSX/STI-AS architecture for certificate requests, call signing, and verification. Successfully implemented the solution within the deadline established by national regulations in France.
Developed a system to monitor network devices and alert commercial agents when customers reached bandwidth limits, increasing sales by 18%. This project highlights my five years of experience in business observability, working with sales and other departments to deliver solutions that align technical insights with business growth.
Implemented a system using Ansible to streamline maintenance and updates for over 200 network devices nationwide. By segmenting the country into regions, I enabled simultaneous updates to 30–50 devices per region, significantly improving efficiency and reducing manual work for the engineering team.
Designed and deployed a centralized syslog server to collect and analyze logs from the entire system, including Linux servers, routers, switches, and other network devices. By storing logs with timestamps in InfluxDB, I enabled real-time visualization of errors, warnings, and critical events. This solution significantly improved anomaly detection capabilities, allowing rapid identification and resolution of issues such as DDoS attacks and major system failures, ensuring infrastructure reliability.
