We introduce homotopy-algebraic structures on Galois cohomology that determine presentations for universal deformation rings of Galois representations. From this, we deduce presentations for universal deformation rings of Galois pseudorepresentations. The latter presentation is used to supply a tangent and obstruction theory for pseudorepresentations. This generalizes the well-used tangent and obstruction theory for Galois representations. We also give an application, calculating the ranks of certain Hecke algebras.
