I have provided constant excel programming support to my previous employer (EWI Cologne Germany). I have skills with automating excel charts, data analysis and database linking. I feel comfortable in interfacing excel with web, PostgreSQL, MS Access etc. I am also an experience programmer in python, C, GAMS, GIS etc. I can provide you best professional services. You can have a look at the recommendation letter I received from my last employer. Any thing else, please let me know!
