Summary
Sebastian Trelles is a senior game designer with 11 years of experience who blends a solid software engineering background with hands-on game design, prototyping and pitching in agile teams. Based in Barcelona and previously working from Copenhagen, he currently drives prototyping processes and gameplay/metagame design at SYBO Games, contributing to titles like Subway Surfers and Blades of Brim. He holds an MSc in Game Design from IT University of Copenhagen and has a track record teaching and mentoring at institutions such as KADK and The Animation Workshop, where he also helped shape curricula. Comfortable wearing multiple hats, he rapidly ships Unity prototypes in two-person teams, pairs qualitative playtesting with data-informed balancing, and documents reproducible design processes. A not-obvious strength is his cross-disciplinary fluency—moving between code, design and production—which lets him translate technical constraints into engaging player experiences.
