I have around 16 years practical experience as Oracle DBA, during this time I have done several things which are not DBA related such as Data Warehouse Support, PL/SQL, PRO*C Programmer, Shell Script Programmer and have done quite a few SQL Tuning. I’ve got also experience with Oracle Application Server since Release 1 (iAS) to Fusion Middleware 11gR2 (WebLogic, Forms, Reports, ECM etc), Oracle E-Business Suite 11i and R12 (as Applications DBA), as well as Grid/Cloud Control, Oracle GoldenGate, Oracle Exadata and Oracle VM x86. Quite fluent in UNIX/Linux environments, to be honest I prefer working with Oracle stuffs under UNIX And Linux environments simply because these platforms commands are so powerful that saves me so much time (and so much customer’s money 😉 ).
I went independent as Oracle Consultant on 2005, since then I have worked for many customers (more than 120). In 2009 I started a small company focusing on Oracle Professional Services, Database Tier 2/3 Advanced Support and short term assignments and projects. For long term projects my role is usually part time Oracle Specialist.
From 2005 I dedicate quite a large amount of my time working with Oracle RAC and Data Guard and specially on UNIX platforms, in the last few years I have been working with a few more complex Extended RAC projects with success. The rest of the time I deal with performance troubleshooting, features implementations (Flashback, Resource Manager, RAT), security, streams, backup and recovery, architecture, sql development, pl/sql, version upgrades and platforms migrations which is not my favourite task until 10g because it is not very amusing spending days exporting and importing, extracting DDL and creating indexes in parallel and nologging, not much to learn! 5 years ago I started working with Oracle GoldenGate and Exadata.
I also participate in quite a few Oracle E-Business Suites projects, most of them migrations and upgrades as technical consultant or Apps DBA. I am quite happy working with EBS although sometimes one can get desperate with it. EBS is fun because you learn a lot with it.
