Ray Barrera was a tinker in his childhood. From making mods and custom maps in games such as StarCraft and Unreal Tournament to developing open source role-playing games using RPG Maker, he always had a passion for game development. The passion stayed with him, and after many years as a hobbyist, he decided to take the plunge into professional development.
In the initial stages of his career, he was fortunate enough to work on educational and research projects for major contractors in the defense industry, allowing him to blend his love for games with his innate desire to teach and create interactive experiences. Since then, he has straddled the line between entertainment and education. Unity was the logical weapon of choice for him as it gave him the flexibility to create games and applications and iterate quickly. From being an original member of the Los Angeles Unity meetup to helping coordinate Unity workshops at local colleges and high schools, he has been very active in the Unity community.
