Looking for Expert on Astronomy (PhD preferred) w/ Knowledge of Armillary Spheres and visualizations
Grzegorz was a complete professional, subject matter expert, and very enjoyable colleague to work with. I am absolutely recommending him at the highest level for anyone else looking for reliable, efficient, engaged, and expert advising in matters relating to his specialty. He was very informed on all the topics of work, quickly turned around deliverables as needed, entertained a very vague hypothetical scenario which only bordered his field but included in depth knowledge of his field without hesitation, and was invaluable on the project. Not only was he an expert in knowledge but Grzerorz was quick to turnaround materials, create 3D models and scripts representing questions posed, and engage in real time discussion and whiteboarding sessions. I surely will be engaging him in the future again once the need arises. Highly highly recommended!
