Vetted C# Professionals

“Unity game developer with experience in both single-player UX-heavy systems and synchronous PvP multiplayer. Implemented a drag-to-target UI flow for a turn-based strategy game that reduced a typical unit turn from ~10 clicks to 1, backed by a modular battle-step architecture. Worked with Photon PUN/Fusion on Cat Simulator 2 (up to 10 players), focusing on data minimization and physics synchronization techniques.”

“Unity gameplay engineer with AAA experience who built a highly configurable weather/day-night system (clouds/rain/sun-moon/stars) that influenced core gameplay decisions (vehicles, time-of-day, farming/animal needs). Also has hands-on multiplayer experience with Photon Fusion (including client-backend communication and physics sync troubleshooting) and has set up CI/CD and build pipelines.”

“Frontend web developer who owned end-to-end delivery for multiple client websites at Vox Interactif and RGI Solutions, including solo launches and rigorous cross-device/browser QA.

Currently upskilling in React by building a custom wiki-style dashboard for fantasy novel worldbuilding.”

“VR/AR game developer and creative leader who has shipped titles to Meta Quest (across Unity/Unreal/Godot) and PlayStation VR. Served as Creative Director and Lead Designer on SafeAR, delivering beyond the brief in a rapid 2-month project, and has also built and coded a Unity mobile puzzle game largely solo.”

“Built and owned a production RAG search/Q&A platform at Data Integrity First for a client with a large, hard-to-search document library, deployed on AWS. Drove major adoption gains by adding source attribution (users trusted answers more) and improved system performance with guardrails, logging, and iterative chunking/OCR normalization—cutting fallback rate from ~22% to under 10%.”

“Unity lead/gameplay engineer who built and shipped Explottens (Apple Arcade) from scratch, including a custom 2D physics system and performance-focused pooling; reports the title generated seven-figure USD revenue. Also integrated an LLM/RAG-driven conversational avatar experience (English/Arabic TTS with lip sync) via a reliability-focused backend layer, and has hands-on Unity Netcode multiplayer experience solving desync and precision issues with deterministic predicted trajectories.”
