Hamiltonian for high energy evolution of QCD amplitudes is presented at the
next-to-leading order accuracy in $\alpha_s$. The form of the Hamiltonian is
deduced from the symmetries and the structure of the hadronic light cone
wavefunction and by comparing the rapidity evolution of the quark dipole and
the three-quark singlet states with results available in the literature. The
next-to-leading corrections should allow for more robust phenomenological
applications of perturbative saturation approach.
