Margaret Wittlinger Sr. Infrastructure Project Manager, CNA Insurance Chicago “Ken is one of the most, if not THE most talented database engineers I have ever encountered. He possesses a strong work ethic, is able to easily break down complex problems into manageable parts rapidly, demonstrates amazing attention to detail, and is patient with lesser skilled / more junior team members. Perhaps most importantly, he is willing to mentor and share his vast knowledge of SQL databases and create teachable moments in a very diplomatic way, which makes the entire project team stronger. Any company that has engaged Ken to provide db services will easily receive more than double a return on the investment.”

Rob Munn Chief Information Officer, Prime Choice Auto Parts Ottawa “Ken Hoca is fantastic at database systems, especially SQL Server. I am more than pleased to share that with anyone who would need his services and professional expertise. Any organization can have success with Ken taking care of their valuable data.”

Fabio de Sant’Anna Principal at Capgemini USA Greater New York & New Jersey “Highly recommended SQL Server Expert. Very competent and easy to work with, very committed and excellent team player. Ken worked for me on a complex stability remediation of the 2 most important policy admin systems of the most critical LOB of a P&C Insurance company. He was there from the initial assessment to figure out problems and recommendations to the end of the remediation and stabilization. Ken was the most critical resource in this project which upgraded SQL2005 to SQL2014, remediated a number of stored procedures, merged database instances, optimized indexes and database settings, to name a few of the actions. These old systems started in a state of outages and too many deadlocks and finished in a state of no outages, much reduced deadlocks and improved response time.”

Karen Harris Manager of Information Technology, The Royal Canadian Legion Dominion Command “To say that Ken is an expert with SQL Server would be an understatement. He is the most qualified person I have ever worked with and would highly recommend him for any database work. His technical skills are second to none. He listens to his clients’ needs and presents solutions that are scaled for their industry and budget. He makes the complex issues seem easier and more manageable.”
