The 18-year-old forward has had to wait his turn since making the switch from Waterford United in January, having made just four substitute appearances prior to Friday night.
He started and scored in victory over Wolves and told West Ham TV: "I'm very happy to be honest with you. It has been a good while coming, before that an ankle injury had me out for about four weeks and I'm delighted now to actually be starting.
"It kicks on from here and hopefully that will be the first of many. I'm looking forward to the upcoming games and hopefully we can end the season strongly.
"I thought I had been training well the last few weeks and the goal was just the icing on the cake. I'm planning to kick on now and get a few more goals before the end of the season."
