William Hu

• Architected a shared Luau module layer that drives human players and AI bots from the same code path: every mechanic behaves identically for both, a single tuning change ships to both at once, and an entire class of player-vs-bot divergence bugs disappeared from the project.
• Designed and built the outfield and goalkeeper AI end to end (ball pursuit, off-ball positioning, possession decisions, passing, shot selection, and save prediction), then tuned it across repeated playtest cycles until bots read as credible teammates and opponents rather than scripted actors.
• Built server-authoritative multiplayer systems (match state, scoring, persistent player progression, item effects) with client-side prediction and presentation, balancing input responsiveness against a server that stays the source of truth.
• Owned progression and content systems from spec to ship: 44 titles, 45 achievements, and 14 gameplay-modifying items, each specified in a versioned design tracker kept in sync with the implementation so design intent and shipped behavior never drifted apart.
• Led moment-to-moment game feel for passing and shooting as the team's soccer domain expert, translating real-match mechanics into readable controls and validating each change through iterative playtests.
• Shipped 700+ commits into a 165k-line, 580-module Luau codebase alongside a team of programmers and artists, with reproducible bug investigation on a live multiplayer build and written design docs that kept a distributed team aligned.
