Collectibol is a digital TCG (Trading Card Game) where players collect and trade officially licensed digital cards from top-tier football clubs, including FC Barcelona, Atlético de Madrid, and Real Betis. Players build their ultimate collections by opening packs, completing seasonal albums, and participating in time-limited events to earn exclusive rewards. 

Some of my contributions to the project:

• Led the design of core features, events and marketplace/trading systems, from a high-level concept to release, focusing on long-term retention and metagame depth.

• Designed and implemented time-limited events that resulted in significant engagement peaks, validating the content-driven strategy for the game

• Balanced collection pacing and rarity distribution for each licensed club release, adjusting drop rates and rewards to ensure a rewarding journey for both non-spenders and paying users.

• Collaborated closely with the UX/UI department to translate design intentions and feature goals into intuitive player flows, ensuring complex systems remain accessible and satisfying to use.

• Produced high-quality documentation to ensure cross-team alignment between Product, Engineering and Art.
