During the last 5 years I have been working in a company that provides a full range of hosting tech support. What does this mean? - quick and complete resolution of your problem. Why quick? - because a customer wants their site to be up and running 99.9% of the time. Why complete? - because if the issue is half-fixed now it may arise in the future and the customer will have to move to another provider who can solve the problem (you know hosting is a highly-competitive marketplace). All these factors are forcing me to have (or gain as fast as possible) a wide range of knowledge in system administration, programming, code debugging and customer relationship.
My core competency lies in SQL Server performance tuning/optimization, designing high availability solutions using replication,clustering,mirroring and log shipping technologies and designing Business Intelligence solutions using SSAS,SSIS,SSRS. My average performance improvement rate is 5000% and for some of my customers I've achieved up to 70000% of performance gain. I'm familiar with data modelling and warehousing principles and skilled on developing business intelligence solutions. I've designed data warehouse and several OLAP cubes for HR Management IS for FINCA,developed SSIS packages to populate them and developed set of analytic reports using SSRS.I've also developed performance metrics analysis solution on the base of SQL Server Data collection,SSAS and SSIS , which allows to easily analyze server's health and quickly spot problem areas. I have also about 20 years of programming experience.Using VB 2008,ASP.net 3.5,SSRS,SSAS,SSIS technologies I've developed and implemented a wide range of data driven desktop applications for various organizations. Good customer service is key for me, and no project is completed until you are satisfied, or l'll offer a full refund.
