Antonios Savvidis

About

Unity developer from the Naer project who built a natural-feeling VR wrist-flick gesture mechanic for teleport/push/pull interactions, validated through telemetry, low-FPS simulation, and diverse user testing with modular ScriptableObject tuning. Also handled Photon PUN 2 networking bug fixes (mid-air item state issues) and RPC optimizations while integrating AI tools (Claude/Gemini/ChatGPT) into planning and implementation.

Education

Key Strengths

• Designed frame-rate independent VR gesture system using controller-based values and cycling buffer for intent detection
• Strong playtesting/validation approach (debug telemetry, simulated low FPS, diverse user testing)
• Modular, tunable gameplay systems via ScriptableObjects enabling rapid iteration from user feedback
• Photon PUN 2 troubleshooting and hardening (failsafes, master-client change handling, cleanup to prevent state carryover)
• Networking performance optimization by reducing unnecessary RPCs and applying Photon optimization guidance
• Effective use of AI tools for task decomposition, architecture refinement, and coding support
