I have been programming 2D/3D games in 5 years. Some of games I've been working involve: First Person Game, Third Person Game, Fighting, Side Scrolling and Endless Running. Most of my games are on PC, some are controller-support, except for Endless Running which is on Android.
For Shooter games, as well as basic mechanisms (moving, jumping, shooting and basic interaction) I can do advanced technique such as RayCast/Physic Bullets, AI, Networking, Complex Interactions, Player - Environment Interactions, etc... I assume that your game is some kind of FPS and survival games, so I believe my FPS/TPS system is suitable for this game.
For more information, you can contact me directly through this sites.
Thank you for your attention.
Best regards.
