  • Thermal optimal path calculation on time-series

    This was a very difficult project that unfortunately ran into some difficulties in implementation. Ultimately the project was unsuccessful, but I am unable to judge the reason since the contents of the project are beyond my own mathematical abilities and I didn't have the time to think through certain difficulties that arose myself. The problem may lie with the source material or the developer and I wouldn't be able tell. The work I did receive back showed some deficiencies at various points but I'm uncertain how much to read into this. Communication was generally good, but there are some open questions on the project which have not to date been addressed; however, they are comparatively immaterial. This was my first oDesk project, and I let it run at its own pace in order to test the concept. The project itself was important, but experimenting with the process was also a key objective. With that in mind, I would not rely on my ratings to assess this developer and in fact the failure of the project probably has more to do with my own deficiencies than the developers.

    Matthew did a fantastic job on my VB.NET and SQL Server project. He is highly talented and did a good job of communicating with me during the project. The quality of his work was the best, I highly recommend him for any VB.NET or SQL Server project.
