I’m Aleksandr Klochkov, a game developer and technical lead focused on gameplay systems, real-time graphics and VR. I founded Arroyo Interactive, a mobile studio with four shipped Unity titles, after working professionally in C++ on a live MMORPG and in Unity on a Mattel racing game with 5M+ installs. B.S. in Computer Science, Cum Laude, from the University of South Florida. Based in Tampa, FL and open to remote or relocation.
