Norbi – Unity, C#, Unity3D

A VR and mixed reality development studio that has delivered 20+ projects, building immersive experiences such as cultural heritage reconstructions, multiplayer training simulations, and location-based VR attractions.

• Founded and led a Unity/C# XR studio, delivering 20+ XR projects for clients on three continents, leading the team through architecture and code review and driving scope and cost decisions directly with clients.
• Architected and scaled an end-to-end LBVR multiplayer platform supporting 20+ simultaneous users across 10+ arcade locations in Romania, with 25,000+ minutes of monthly usage, the first and only deployment of this scale in the country.
• Built a collocated multiplayer training simulation for Airbus A320/A321neo cabin-door procedures, with networked state replication, finger tracking, and an operator monitoring dashboard, designed to replace costly physical training programs.
• Delivered a 3-site VR reconstruction of Neolithic and Roman heritage sites, using AI-generated 3D assets and voice synthesis (Meshy, ElevenLabs), a custom low-poly vegetation renderer for standalone Quest 3, and a real-time RO/EN/BG localization pipeline driven from a content spreadsheet.
• Built a voice-driven AI agent system for multiplayer mixed reality (speech-to-text → LLM → spatial-audio text-to-speech) with switchable cloud, on-prem, and local inference for cost-efficient scaling.
• Built a custom chunk-based fluid-physics engine (buoyancy, hydrodynamic resistance, turbulence) for a VR engineering simulation at interactive frame rates for a European technical university.

A cross-platform VR research tool built with Babeș-Bolyai University's Psychology department. One codebase powers PC, VR, Android, and iOS (95% shared code). The platform handled data collection from over 1,500 participants, generating 100k+ entries backed by Firebase real-time database and an offline mode fallback. Available on Steam, Play Store and App Store.

• Led development of REThink Life, a VR research tool for Babeș-Bolyai University's Psychology department. Delivered results that led to full ownership of development and maintenance.
• Re-architected the app for cross-platform support across VR, Android, iOS, and PC with 95% shared code and published it on Steam, Play Store, App Store.
• Integrated Firebase, collecting 100k+ entries of psychological data from 1,500+ participants, and prevented data loss on 1,200+ entries with an offline C# database backup solution.

AR football training app with 5 AI-powered drill modes, eliminating the need for a training partner. Built for XREAL Glasses with surface detection for precise ground-plane AR and an interactive scene placement feature that saves ~15 minutes per hour of training.

• Developed an AR football training app for XREAL Glasses with 5 different AI-powered drills, designed to improve solo-training efficiency and remove the need for training partners.
• Implemented custom virtual collision and height-based surface detection using the XREAL SDK, enabling real-time feedback and accurate object placement on the ground.
• Reduced training time by ~15 minutes per hour with a scene-reset feature that re-anchors the experience to the user's real-world position at any given time.

Full-stack eLearning platform serving 1,000+ students and teachers across 7 school labs in Bucharest, built with the Romanian Ministry of Education. Features real-time session hosting, whiteboard synchronization, 3D model interactions, live quizzes, and data exporting. Increased student engagement and cut annual infrastructure costs by $12,600+ with a self-hosted networking solution.

• Managed the full lifecycle of an eLearning platform developed with the Ministry of Education, used by 1,000+ students and teachers in 7 modern laboratories across Bucharest, Romania.
• Implemented 100% of the client's requirements, including real-time session hosting, whiteboard drawing, 3D media presentation, quizzes, user evaluation, statistics, and data export.
• Improved scalability and saved $12,600+ per year by implementing a self-hosted C# networking solution that removed the dependency on cloud-dedicated servers.

Pawns to Kings: Online multiplayer chess platform built from scratch for a client in Ghana featuring authentication, matchmaking, leaderboards, and friendly match modes.
