I have over 20 years of experience as an Application Architect/Developer, a Database Administrator, and a Project Manager in a wide variety of business applications with a primary focus on performance.
During the past 15 years, my main focus has been on becoming a performance expert. In doing so, I have accumulated extensive experience and knowledge in programming in Java, Delphi, and C++, as well as gaining a deep and extensive expert knowledge in database design on DB2 (both on LUW and z/OS ) , Oracle and MySQL/MariaDB databases. Not to mention expertise in SQL language with a main focus on queries in medium to larger, database, and data-warehouse environments.
Additionally, throughout the past decade, I have done independent research on best application and database design practices to enhance optimal performance. I thoroughly enjoy researching various aspects of Database performance and technologies in my free time and often share my findings with coworkers and colleagues around the world.
Through my research, I have obtained a broad understanding of development best practices and gained extensive experience in UML/RUP and other technical development/project management standards such as Prince2, Kanban, and Agile.
My main interest lies in client/server programming and distributed relational database design using DB2, Oracle, or MySQL/MariaDB.
Overall, I am an extremely self-motivated individual and have demonstrated an exceptional aptitude for new/current/legacy technologies and problem-solving skills in every project in which I have taken part.
