Technical Skills

Expanded Experience

Unity VR Developer

Nursing Simulation Training Software

• Developed over 100 VR simulation features for nursing education, focusing on medical procedures (e.g., IV insertion, auscultation, NG tube suctioning) and patient interactions across adult and pediatric scenarios.
• Built modular Unity systems using the Model/View design pattern, applied to control panels, wrist menus, EHR interface, Hook UIs, and supply cart interactions.
• Implemented dynamic VR UI components such as tooltips, wrist-mounted menus, floating labels, and checklist systems to guide users through clinical workflows.
• Engineered complex medical equipment mechanics, including IV infusion pumps, blood culture sampling, NG tube attachment systems, and suction regulators with real-time physics behaviors.
• Integrated hardware feedback and sensors to synchronize physical object manipulation (e.g., IV bags, blood pumps) with virtual interactions and animations.
• Diagnosed and resolved critical VR multiplayer synchronization issues, cross-platform exceptions (Meta Quest VR and PC VR), and real-time state desynchronizations.
• Collaborated closely with medical experts and instructional designers to align scenario designs with real-world nursing protocols and best practices.

Industrial Training Simulations

• Developed a VR training simulation for electrical circuit breaker maintenance, requiring users to select proper PPE, perform hazard checks, coordinate with a switchman, and complete a full racking procedure.
• Designed a progressive learning system with three training modes: fully guided, semi-guided, and open-world, where task sequence errors resulted in failure, reinforcing real-world safety protocols.
• Integrated real-world physical equipment with VR via sensors, allowing users to see and control live equipment movement within the simulation.
• Built a VR inspection experience for large mining equipment, enabling users to teleport around machinery, inspect components, identify hazards, and interact with moving parts like doors.
• Enhanced user navigation with guided visual cues and an animated robot demonstrating inspection procedures.
• Optimized performance for both Oculus Rift, Oculus Quest and Oculus Go VR hardware, tailoring controls and visuals for platform capabilities.

Unity Games Developer

Indie Games

• Develop and publish small games on https://dgsoftware.itch.io, focusing on both original creations and recreations of classic titles like Pong, Breakout, Asteroids, Space Invaders, Diamond Mine and Tetris.
• Design a highly customizable, modern version of Othello, supporting 2-4 players (human or bots), adjustable board dimensions (8x8 to 16x16), randomized tile blockouts, and speed-based Dash Mode with timed turns.
• Experiment with innovative design techniques, including vector-line and voxel-based versions of Asteroids and Space Invaders, featuring dynamic destruction effects.
• Revive and modernize older games, such as Alien Invasion, a resurrection of a 1999 space shooter, and create new original titles like Tank vs Tank, a head-to-head tank battle game.
• Develop educational games like Mathscape, a multiplayer dungeon escape game that challenges players' math skills in a collaborative environment.
• Recreate mobile games such as Unblockable and Ballz, adapting mechanics for fresh gameplay experiences.
• Adapt traditional game genres into VR experiences, including the Unity Tower Defense Template (playable from a full-map or first-person perspective) and a Shooting Gallery optimized for immersive 2D and VR play.
• Designed and published a suite of family-friendly games for young children using Unity (URP) and C#. Built intuitive, touch-optimized interfaces with Unity UI Toolkit and Input System. Developed reusable gameplay systems, browser-based text-to-speech, and dynamic camera/environment effects. Deployed to itch.io (WebGL/Android), optimizing builds for low-spec devices. Handled all design, coding, UX, and publishing.
