Add real time multiplaying option in android word game

Hello Sir/Mam, I am a professional game developer with more than 6 years of experience in this field. I would like to help you with the multiplayer option you wanted to add in your existing game. I am expecting 25USD for this work and timeline will be 3 days with daily basis updates. Kindly let me know which game engine you are using for the game and lets get this done. Thanks
