The striker joined the Stones back in February from Ryman League Premier Division side Grays Athletic and it was his last-gasp goal against Ebbsfleet United in the National League South olay-off final that took the tie to a penalty shoot-out.
Twenty-two-year-old Dumaka chipped in with 6 goals in fifteen appearances for Maidstone to add to the 22 he scored while at Grays.
