Interactive Brokers API for historical time and sales
Paul was great to work with on developing our interactive brokers script. The script he built saved us hours of manual work each day.

Help me extract historical Futures data from Interactive Brokers TWS API in C++
Paul was a genuine pleasure to work with and I will definitely work with him again as my needs grow. This was Paul's first contract as a freelancer on UpWork but he presented himself, communicated and delivered way above and beyond my expectations of even the top-tier freelancers I have worked with.
In addition to his notable proficiency in Python, I was impressed with Paul's ability to repeatedly provide valuable insights and suggestions that improved the final deliverable well beyond what I had originally envisioned, so I am extremely happy with the outcome.
Paul's knowledge of and facility with API development made our project made my complex requirements for data extraction and workflow automation seamless.
He offered very timely turnaround in implementing fixes and adjustments I requested.
And finally, Paul was diligent in ensuring requirements were understood clearly before we ended each call, and I was very satisfied with his responsiveness, so Paul's communication skills throughout the project were excellent, even by my standards.
Highly recommended, 10/10.
