Are you looking to bring the benefits of data analysis to your business? Or maybe you already have analytics implemented and you are looking for eye catching reports to display your metrics.

Working with Tableau, Excel, Microsoft Business Intelligence Studio (SSIS, SSAS, SSRS), MS SQL Server and MySQL. I build solutions to suit your business needs.

My job is to take your data and visually convey it in a way that entices, engages and moves your audience to an action.

My specialties are:
-Captivating, data driven visualizations that catches and keeps your audience's attention
-Data Analysis, Data Warehouse and Data Marts built to solidly support your visualizations
-Custom queries and procedures designed for real time blazing fast performance
-Identifying, designing and building you dashboards that really matter
-Teaching SQL to students in a fun (NON-bore-you-to-death) kind of way. It's my passion.

So the why not focus on running your business and let me take care of the headache creating queries, mind numbing ETL processes, hair loss data warehouses and data marts and create your stunning data visualization dashboards.
