As I worked in IT sector I know some program languages. 
My very strength is SQL. Well, it is not exactly a programming language, but I have to mention it. I have more than 5 years experience in SQL and MS SQL Database.

As I work a lot in Excel and Access, I am familiar in VBA language. I use it for creating various features in Excel and Access, and make automatic workflow.

My new favorit is Python. I teach it for students in high level exam. I use this language analyzing data and make queries more and more efficient.
