I have been running my company, Erland Sommarskog SQL-Konsult AB, since 2007. The purpose of this company is to sell my expertise in the SQL Server field. There are no other employees, nor do I plan to employ someone.
My current situation is that I have a main client for which I work on daily basis. My role there is a systems developer, working almost exclusively in T-SQL on SQL Server. However, this is not really a full-time engagement, so from time to time I take on other clients for shorter engagements on part-time basis. Many of these gigs are around performance tuning, which can be on an overall basis, or just tuning of one query which is critical for the client. Beside performance tuning, I can also act as a speaking partner to give general advice about directions a development team should take, and other architectural solutions around SQL Server development. When it comes to more direct DBA tasks as HA/DR, I do possess some knowledge. However, since I have never worked as a DBA, I don't have the same level of experience.
Beside my consulting business, I regularly speak at conferences, mainly in Europe, but I have also spoken a number at times at the PASS conference in Seattle. Furthermore, I'm active in SQL Server forums and I maintain articles on my web site. Overall, I have a passion for sharing my expertise with the community.
I have been a Microsoft MVP for SQL Server and Data Platform since 2001, which is a token of my expertise, but also of my passion of sharing with the community. Being an MVP means that I have access to other MVPs and SQL Server Developers in an internal forum, so if I run into questions where I don't have the answer myself, I might be able to get help through that channel.
If you are interested in my services and drop me a line on esquel@sommarskog.se. If you want me to be on site, you should know that I live in Stockholm, Sweden, and I will charge for travels. Would you like a résumé, I can supply one on request, but I'm not keeping it available publicly anymore. (I found it too embarrassing. My technical skills by far outshine my marketing skills.)
