If given a chance I'd like to learn more from him about the subject

This project has been the best experience I've had on Freelancer. Joe is easy to work with and extremely responsive to inputs and questions. This project involved implementing a Kalman filter with multiple parameters over noisy financial data. Joe's updates were presented in a fantastic and easy-to-digest format, which made collaboration easy going forward. I HIGHLY recommend Joe for any project involving R, times series, signal processing, filtering... or anything that requires some heavy mathematical lifting.

Joe did a great job researching historical pricing for some bonds I needed to determine the cost of. I would definitely hire Joe for similar project work in the future.
