Hi, I think of myself as a problem solving expert. Yet, I'm completely stumped by your requirement. How are you combining dates with angles? How do you measure angle between two dates? It baffles me, and makes me curious. That's the only reason I'm bidding on this project - to get some answers.
For my background, I have a master's degree in computer science, over 15 years of experience, and I'm a published author of books on Data Structures & Algorithms, and Computer Programming. I routinely help graduate/post-gradate students, and even doctoral candidates with various tools & utilities required in their academic pursuits of top grades, coded in C/C++/Java/Python.
I believe in first time right delivery, and this commitment is reflected in my 5-star rating and 100% completion rate. I believe I am a good fit given your requirements.
Looking forward to getting some answers for my queries about this project, and establishing a basis for an ongoing professional engagement.
Thanks,
Gaurav
