Architected the entire game economy from scratch—defining resource production rates, consumption
sinks, and trading floors to ensure a stable, non-inflationary market.
Engineered all combat formulas and attribute scaling (ATK/DEF/HP) using exponential growth curves
to keep late-game progression satisfying without breaking PvP balance.
Designed the player leveling curve and tiered item-rarity system, aligning upgrade costs with expected
daily playtime (targeting 45-minutes of active engagement).
Delivered a complete monetization framework (seasonal passes, gacha rates) ready for integration
before project restructuring.

Projects: plus multiple prototypes
Built a reusable numerical framework (growth values, economic baselines) that was applied across 4+
simultaneous mini-game projects, reducing design time for new titles by 40%.
Designed real-time multiplayer party mechanics for TikToks short-form platform, optimizing for 60-
second match durations to maximize user retention.
Prototyped a Cyberpunk Kung-Fu simulation and a 4X Awakening strategy game, delivering fully
playable demos within 3-month sprints.

Projects: the design of5 simultaneously, a team of 4junior designers—assigning
tasks, mentoring, and conducting quality assurance on all design documents.
Pioneered the narrative-interactive genre for the company, adapting novel-style storytelling into a
card-collection RPG framework (Sweet Loving Game).
Directed the full lifecycle of Guarding Meow Meow (puzzle mini-game):
Designed 100 unique levels with escalating spatial complexity and interactive block mechanics
(Burst/Fly/Shake).
Tuned difficulty curves to achieve a 50% NRR and 10, 000 DAU.
Won the Top 10 Small Games Award from 360 Games in 2019.
Optimized the idle/breeding mechanics of Breeding Cat, adjusting timer-to-reward ratios to increase
daily active sessions by 25%.

Projects:
Designed the full loot-drop tables, dungeon difficulty scaling, and item enhancement systems for two
high-revenue ARPG web titles.
Scripted game logic and quest flows using Lua, maintaining the live database (MySQL) for item
balances and bug fixes.
Achieved $1M+ monthly revenue** for *SAO* and **$100K+ monthly revenue for Blade Soul through
aggressive event scheduling and combat tuning.

Transitioned from mechanical engineering to games. Handled order management, technical drawings,
and client support.
