I am an experienced data architect modeler, engineer for relational and data warehouse systems. I have expertise in PostgreSQL, Microsoft SQL Server, Oracle, RedShift, and MySQL databases. I have experience managing databases in Amazon’s AWS RDS and Aurora. I worked at Vendini as a Database Architect and American AgCredit as an ETL and SSIS engineer. I’m worked at Employers, Reno, NV as a Senior Data Modeler. I was Senior Database Architect at Sonoma Technology (STI) for 13 years. I have designed and developed most of their databases. These include the Environmental Protection Agency’s (EPA) AIRNow database which acquires and analyses air quality and meteorological data for the entire US plus Mexico, Canadian, and China sites (airnow.gov and airnowtech.org). I am an expert SQL developer, stored procedure writer, debugger, and database performance tuner. I’m an expert data modeler for business and scientific data having designed many data warehouses and relational databases. I have researched new techniques and prototyped new approaches to make software and database systems flexible and fast for very large databases. My experience prior to Sonoma Technology has been in a wide range of fields, from designing permitting applications for the U.S. Department of Housing and Urban Development, legal and human resource databases, decision support systems for hospitals, to a variety of industrial instrument control systems. I have also developed accounts receivable and payroll, contractor estimation, and wine and newspaper inventory databases and applications.
