Security
As a Lead Unity Game Developer I treat security as an architectural foundation, not as an afterthought. I design systems with clear trust boundaries, backend authority, and predictable behavior from day one.
This approach has proven critical in live multiplayer titles, economy-driven games, and mobile productions where client manipulation must be prevented without sacrificing performance or development velocity.
Trust Boundaries & Client as Untrusted
I always treat the client as an untrusted environment. Client code handles presentation and input, but never authoritative decisions about progression, economy, rewards, or competitive outcomes.
Backend Authority as Single Source of Truth
All sensitive game state (progression, inventory, economy, matchmaking) lives on the backend. Validation and enforcement happen server-side only. This significantly reduces the attack surface and prevents client-side exploits.
Economy & Progression Protection
In games with real progression or in-game economies I design deterministic, auditable flows. All critical state changes are validated and persisted through backend-controlled processes — never trusted to the client.
Multiplayer Anti-Cheat & Abuse Prevention
For multiplayer titles I implement clear authority models, server-side validation, state prediction with correction, and anomaly detection. Reconnection handling and anti-cheat measures are considered from the very beginning of architecture design.
Prototype vs Production Security
During early prototyping I allow controlled shortcuts for speed. When moving to production I systematically review and harden all trust assumptions, remove debug paths, and ensure temporary solutions do not become permanent vulnerabilities.
Operational Security & Monitoring
I design systems that support proper environment separation, configuration management, and observability. This enables rapid detection and response if something unexpected occurs in live operation.
Core Security Principle
Security is not about making the game unhackable — it is about making exploits predictable, detectable, and economically unattractive while keeping the game fun and performant for honest players.
