An approach is provided for construction and aggregation of distributed computations. A distributed computation construction infrastructure identifies an execution context bound to a user context at a device, the execution context corresponding to one or more processes executing at the device. The distributed computation construction infrastructure further causes, at least in part, decomposition of the execution context into one or more closure primitives and respective process states, wherein the one or more closure primitives represent computation closures of the one or more processes. The distributed computation construction infrastructure also causes, at least in part, serialization of the one or more closure primitives, the process states, or a combination thereof. The distributed computation construction infrastructure further causes, at least in part, aggregation of the one or more primitives and the respective process states to reconstruct at least a portion of the execution context based, at least in part, on consistency determination.
