About

Unity gameplay developer who led implementation of an airport scene for Duplo Town (children’s physics/exploration game), adding multiple unspecced interactions that significantly increased polish and playfulness and delighted testers/clients. Principal/lead-level engineer with strong sprint planning and impact-vs-effort prioritization, plus experience designing asynchronous client-server interactions and state management (aware of Photon-style real-time multiplayer sync).
