As a member of the middle management for a BPO company catering to international and local clients, I did a lot of Data Gathering, Data Entry, Data Analysis and presentation using MS Excel, MS Word and MS PowerPoint. The process involved exporting raw data from the clients' websites, a lot of excel computations, pivot creation, graph creation and interpretation of the results of operations to the clients and higher management. Trend analysis is also done and reported during Weekly/Monthly Business Reviews. Attention to detail is very much needed and practiced during reports creation and results of operations discussions.
As a freelancer I have no experience but as somebody who has worked with Excel, Word and PowerPoint for more than 12 years as an Accountant/Auditor, Quality Analyst, Supervisor, Senior Supervisor and Associate Manager, I have the experience and knowledge that you require to get the job done with accuracy and at the shortest time possible.
