I`ve spent the past 25 years mastering (not sure that word can be used anymore) the Oracle technology space. I started with Oracle 7, learning and burning from the ground up. As the first Oracle DBA at Best Buy, I was able to learn by making a ton of mistakes, the best experience one could ask for. I have mastered most of the the Oracle critical functions (Administration, Backup and Recovery (RMAN), Disaster Recovery (Dataguard), Performance Tuning, High Availability (RAC), Monitoring (Enterprise Manager/Cloud Control), etc). I`ve worked on databases ranging from a few hundred gigs to 55+ TB. The past several years, while continuing to be a lead for Oracle, I`m working on mastering Datastax Enterprise (Cassandra). I`ve been the lead DSE administrator for Best Buy. I have been certified in DSE 5.0 and am working on DSE 6.x of late. I`ve also started dabbling in Azure Cosmos DB with the SQL (Document DB) and Cassandra APIs. I`ve also started, designed, developed and implemented multiple internet businesses - some somewhat successful, most not - but the learning from doing all of the above is well worth it. Some highlights of my career (some repeated from above): Programming: * I have extensive programming backgrounds in C (25+ years), ksh (25+ years), java (10+ years), HTML (15+ years), Javascript (15+years), php (5 years), etc. Oracle: * I spent several years as a consultant, some of that time at Oracle corp. * I have owned several small companies and continue to have one that I`m heavily involved with. * I have taught public classes on a variety of Oracle and Operating System topics. * Occasional consulting mentoring * For my latest off-hours project, I`m the DBA, web developer, designer, architect, UNIX admin, network admin, HTML/CGI coder/designer, security-admin, etc. * Most DBA related activities for the past 25 years - Backup/Recovery - RAC - Performance analysis/tuning - Monitoring - Dataguard (DR) - Administration - Trouble-shooting - Networking - Design DSE (4.8 - 6.0) Installing DSE (building cassandra clusters) Expanding clusters Upgrading clusters Security Encryption SSL/TLS, and TDE Multi-node DSE Performance analysis and configuration Design Backup/Recovery I love all of the above!
