Trained in statistics (5th year of university in statistical methodes) and well-off with manipulations on Excel, I could realize easily your missions. I'm accustomed to use Excel, I'm a real expert (+ macros VBA). It will be easy for me to create your sheet or analysis. I worked in big companies and I realized international projects. You can develop trust in me, I'm competent, contentious and efficient. I’m waiting your proposition.
