Developed the complete scripting implementation for a social/fashion Roblox experience, covering core gameplay, progression, UI logic and backend systems.
SOLO PROGRAMMER
Football AI Simulation - Experimental Project
Developed an experimental football simulation focused on autonomous team behavior and tactical decision-making.
The project included Utility AI, positional roles, team-level tactical behavior, spatial reasoning, player decision systems, and custom debugging/visualization tools for inspecting AI behavior in real time.
The goal was to explore systems capable of producing coordinated football behavior inspired by football simulation games such as FIFA or PES.
SOLO PROGRAMMER / GAME DESIGNER
Soccer Simulator League — 2023
Developed a football club management game centered around building a long-term history with your own club.The game featured a five-division league system with promotion and relegation, club progression, season-based competition, and management systems designed around taking a team from the lower divisions to the top.The project focused on creating a sense of long-term progression and identity, allowing players to build their club over multiple seasons rather than treating each match as an isolated experience.Systems: League progression, Promotion & Relegation, Club Management, Seasons, Match Simulation, Player Data, Progression Systems
