Card Guardians

Game Designer · Tapps Games · Jun 2025, Present

Welcome to Valentia, a magical world consumed by chaos, where only true heroes can survive.

Face powerful monsters and intense battles in a strategic card game inspired by the best roguelikes. Build your deck with unique cards, craft strategies for every challenge, and adapt your playstyle with each new journey.

In Card Guardians, every battle is a war and every choice can change your destiny.

In Card Guardians I worked as a Game Designer focused on gameplay systems, combat balancing, progression design, and Live Ops content. My responsibilities included designing, implementing, and iterating card balance, enemy encounters, reward structures, and progression systems to create engaging and highly replayable gameplay experiences.

I also contributed directly to gameplay implementation and feature iteration inside the engine, collaborating closely with engineering, art, and production teams throughout development. In addition, I worked on Live Ops events and feature improvements using A/B testing and player behavior analysis to optimize retention, engagement pacing, and long-term progression.
