What People Say

"I've known Tim for over a decade and worked with him on the Business Intelligence team at Six Flags. He is a leader in this technology space and is very well known throughout the region through the hundreds of hours he's donated to teach Business Intelligence and Data Analytics. He was an incredible addition to our team and immediately made an impact on our deliverables. He rapidly picked up our entire architecture, methodology, and development processes and took on a major project in our backlog within the first week of joining. He has a skill set that surpasses just about every other professional I've ever worked with in this technology space and was the heavyweight on our team for dimensional modeling, data marts, and visual analytics. I would strongly recommend him and if given the opportunity would hire him anywhere I am as I would very much like to work with him again."
"Brindle Solutions was able to help us most when we lacked the in-house skillset to handle a highly complex project. Brindle Solutions’ process was quick and thorough which saved our team countless hours. It was the perfect end-to-end engagement for our business that allowed our team to focus on other items while Brindle Solutions took point on this project. We were able to scale their solution out to all branches within our company successfully. We are very pleased with the work they do and look forward to continuing to work with them in the future."
"I first heard Tim speak a few years ago at CodeStock. He presented on Date dimensions for Kimball Data Warehouse models and he knocked it out the park. Not only is Tim a gifted technologist, he's also a conscientious solutions developer. His background in database administration means Tim is thinking DevOps during the development cycle without trying - he's been there and done that, so his BI solutions are designed with support in mind. Tim possesses that great combination of strong work ethic and integrity. I recommend Tim Costello for BI project leadership and delivery."
"I worked with Tim on the Business Intelligence team at Six Flags. I had known Tim for a few years through the SQL community where he presented Business Intelligence topics at many conferences. I was extremely impressed with how quickly he picked up on our methodology and business processes. Tim was a valued team member who brought his skills and expertise in analytics and specifically visual analytics to the team. I highly recommend Tim and would love to have the opportunity to work with him again."
