Scott S. McGeary

BI/Reporting Data Architect

United States - Tests: 2 - Portfolio: 4

With 16 years of experience in the public and private sector, I bring a vast spectrum of experience from many platforms and technologies. I started my career doing web development for several years and migrated into data warehousing, reporting, data management, data automation, and pretty much anything you can think of that deals with data. The Microsoft SQL Server BI Stack is my wheelhouse, but I use many other tools beyond SSIS and SSRS, such as Tableau and Crystal Reports. I enjoy solving extremely complex data issues with my skill set. My passion is making data "work" for my clients. I still do a bit of web development for clients and am very proficient in Classic ASP web apps. Let's talk about your project and see if I am a good fit!
