Looks to me like you may have a blue-fruited Dogwood bush, Cornus sp. The opposite, non-toothed leaves with veins that follow the edge of the leaf and bluish fruits in panicles lean toward this. The common eastern Dogwoods with blue berries are Stiff Dogwood, Cornus foemina (leaves green below, southern US); Narrowleaf Dogwood, Cornus obliqua (leaves white below, northern US); Silky Dogwood, Cornus amomum (leaves rounder at base than these); and Roundleaf Dogwood, Cornus rugosa (rounder leaves than these, purple blotched twigs).
