I am an Oracle9i OCP DBA. I have an experience in Oracle/UNIX administrating including install, setup, configuring, tuning for optimal performance, maintenance and troubleshooting.
I was involved in two big migration projects during last 1.5 years: first one was 8.1.7.4 to 10.1.0.2 migration of huge Data Warehouse system. Second one was recent migration  of banking hybrid OLTP/DSS complex application. In this latter case source version was 9.2.0.5 and target version is 10.2.0.2. In both cases I was responsible person for developing backup-recovery strategy and providing tests for disaster recovery with using the same standby server.
Also I was consulting our local company conducting migration from 9.2.0.7 single-instance mode to 10.2.0.2 RAC for mission-critical heavy loaded OLTP application with minimal allowable downtime.
Another critical-mission project I was involved in is DG setup for two-node RAC and RMAN backup strategy preparation for this HA solution.
I can play a role of a second (night) support administrator working remotely or I can provide part-time consultation on regular basis.
