The ground state masses and binding energies of the nucleon, $Λ^{0}$ , $Λ_{c}^{+}$ , $Λ_{b}^{0}$ are studied within a constituent quark QCD-inspired light-front model. The light-front Faddeev equations for the $Qq q$ composite spin 1/2 baryons, are derived and solved numerically. The experimental data for the masses are qualitatively described by a flavor independent effective interaction.
