Lead Interactive Developer at KoffeeCup

January 1, 2024 - Present

Secured project funding through 2026 by delivering the core multi-platform project serving as the client’s central technical ecosystem foundation. Orchestrated a 13-engineer development team under high-volatility production cycles, maintaining delivery despite weekly requirement shifts and undocumented engineering constraints. Conceptualized and developed the “Duel” prototype for “Wild West Salon”; added creative mechanics that were spun off into a standalone MR world, “Gunslingers,” following executive and client approval. Resolved internal architectural deadlocks by delivering a VR interaction prototype in 48 hours that exceeded client quality standards, securing system-wide endorsement. Mastered Meta’s proprietary engine to bypass technical debt and launch multi-platform persistent worlds within undocumented system limitations. Standardised engineering workflows and upskilled senior talent to ensure technical stability across parallel Live-Ops and feature content lan
