I have worked as data analyst and cost estimator for 3 years in one of quite well known Coal Mining and Construction company in Australia, in which, branch is in Indonesia, and there are quite a lot of manual work processes relating to data processing that i have improved with my own vb-excel creation, or even help my boss with semi manual excel step by step procedures to be implemented for the division.
I did the similar stuff in one of Multi National Oil and Gas Company in Indonesia, as an expert/analyst.
Please contact me for further information of what i did in my professional career.
