For the last 20 years I have worked with Relational Databases as a database designer, DBA and developer. I have concentrated in designing and developing large, high volume databases and high performing queries. Many of these queries support automated processes to achieve high application flow through rates. Other queries automate common human tasks to eliminate cost, reduce errors and improve Time to Value. Others provide external access to the data without the need to understand the database structure. I have provided production support for several client companies. Several of my projects have included conversion projects. Sometimes they were database to database and others were data extracted from other systems and inserted into the relational database. I am proficient in SQL, Stored procedures and packages, triggers, sequences, PL/SQL, Java, Unix and Linux shell programming, Microsoft Office (Word, Excel, PowerPoint and Access), Python, PHP and HTML. I have used Oracle, MySql, Postgres, Access and MS SQL Server. I am looking for a freelance work where I can utilize my extensive relational database background to help provide quality products and solutions.
