I am fully comfortable with Excel and also other MS tools. But nowadays, the ability to use these tools is not that much valuable by itself. You should understand the problem, business, model, simulation, whatever you are working on, very well and be creative implementing the necessities on spreadsheets. This is where I make a difference.
I am mostly online. If you think you have a suitable work, just invite me. So that we can discuss and think on your job together.
