As the main point of contact for all Oracle-related operations within the company, I managed and delivered multiple client assignments across diverse environments. My role involved leading end-to-end database projects — from assessment and architecture design to implementation and optimization — with a strong focus on successful migrations from on-premises Oracle infrastructures to Oracle Cloud. Known for hands-on expertise, reliability, and solution-driven execution, I consistently ensured smooth transitions, minimal downtime, and measurable performance gains for each customer engagement.

From my daily work agenda I can easily mention that ensuring the functionality and performance of the Oracle databases that I manage and working toward solving the incidents and doing current tasks that involve solving issues and problems with the purpose of making sure that the agreed SLA are met are my top priorities. In essence, I am currently providing Level 2 support for Oracle related incidents and problems and I handle all service related events within the target SLA, delivering requested changes and diagnosing problems in order to provide the complete resolution to the customer and meet their high expectations. I ensure that the appropriate systems and applications are installed, configured, monitored, managed and maintained in accordance with the Company’s policy and industry best practices, but I am also developing scripts for extending the functionality of the installed IT solutions or for automating the recurring activities. Optimizing the existing solutions by redefining the current setups or by making upgrades to increase the efficiency and meet the new business requirements also are on my agenda. I perform proactive maintenance activities based on the information gathered from monitoring tools and automated alerts or notifications. I am always open to new challenges and new incoming projects in the database area and like to help my colleagues as often as I can, especially if they need help with Oracle installations, upgrades, RMAN issues, Dataguard Sync issues, Datapump Exports, etc.
