  Based on the solution of \textbf{Paulsen Problem} by Kwok, Lau, Lee, and
Ramachandran [\textit{STOC'18-Proceedings of the 50th Annual ACM SIGACT
Symposium on Theory of Computing, 2018}] and independently by Hamilton, and
Moitra [\textit{Isr. J. Math., 2021}] we study Paulsen Problem and Projection
Problem in the context of Hilbert C*-modules. We show that for commutative
C*-algebras, if Modular Paulsen Problem has a solution, then Modular Projection
Problem also has a solution. We formulate the problem of operator scaling for
matrices over C*-algebras.
