About me

Senior Oracle DBA who has spent nearly 30 years keeping critical databases running for telecom, finance and retail, including years at Oracle itself. I prefer a short call, a written plan before touching production, and clear documentation at the end. Based in Italy, working remotely.

Senior Oracle DBA with nearly 30 years in mission-critical environments: telecom, finance, retail and Oracle Corporation itself.

I help companies keep Oracle databases fast, available and safe:
  • Performance tuning: slow SQL, AWR/ASH analysis, capacity and workload issues
  • High availability: RAC, ASM, Grid Infrastructure and Data Guard (setup, switchover drills, DR plans)
  • Oracle Exadata (X2-X10): patching, upgrades and tuning. I have run a fleet of 15 full racks in a 24x7 telecom environment (500+ databases)
  • Migrations and upgrades (11g -> 12c -> 19c/23ai, on-premises -> OCI) with minimal downtime
  • Backup & recovery with RMAN, OEM monitoring, health checks and audits
  • Corporate training: Oracle 19c, RAC/ASM, Backup & Recovery, delivered in English
Also PostgreSQL and MySQL/MariaDB monitoring, on Linux, AIX and Solaris, with shell scripting for automation.

How I work: a short call to understand the problem, a written plan before touching production, and clear documentation at the end.

Based in Italy (CET), 100% remote, available for English-speaking projects across Europe. Working languages: English and Portuguese; conversational Italian.
