About Rodolfo

I am an IT Operations Analyst with a strong background in 24x7 Mission-Critical Environments (Energy Sector). I bridge the gap between Systems Administration, Network Stability, and Operational Security.

Security & Ops: Log analysis using Splunk for security auditing. Identity management and incident response (P1/P2).
Observability: Implementation of monitoring solutions (Dynatrace, Elastic) to prevent downtime.
Why work with me?
Beyond technical skills, I bring 20 years of leadership and crisis management experience. I stay calm under pressure and communicate clearly during incidents.
