Analytical Projects that you've done before

For the benefit of everyone, I thought it would be helpful if the WSO community would be kind enough to share their experience and responsibilities with analytical projects in any finance field; Trading, Equity research, fixed income, portfolio management, client service, etc.

If possible, can the contributors state their job title when working on the project. If for any reason you feel uncomfortable doing that, it's ok to remain anonymous.

Please and thank you WSO community!!!!
