Unity VR Developer

Nursing Simulation Training Software

• Developed a wide range of VR simulation features for nursing education, covering 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 Apps Developer

Home Design Visualization Software

• Developed 3D home modeling software where individual rooms were created as modular, standalone components and assembled like a puzzle to form complete house layouts.
• Built a wall generation system with intuitive drag-and-stretch controls, enabling users to place, modify, and resize walls in real time, with dynamic dimensions displayed.
• Engineered smart corner handling to automatically align walls at varying angles and thicknesses, including support for sloped and curved wall designs.
• Improved the placement and duplication of windows and doors with real-time snapping and dragging mechanics for a smoother user workflow.
• Designed and implemented complex triangulation algorithms to handle wall surface faceting, curved geometry, and clean joins between internal and external wall layers.
• Customized a generic 2D triangulation library for 3D use cases, including extending end lengths for seamless corners and adjusting wall thicknesses to prevent rendering conflicts.

Unity Games Developer

Published Indie Games (digitalriftgames.itch.io)

• Shipped multiple polished titles on itch.io, including Reversi 2 Dash 4, Mathscape, Tank vs Tank, and Shooting Gallery, each with distinct mechanics, UI flows, and platform-specific tuning.
• Built customizable board-game logic for Reversi 2 Dash 4 with variable board sizes, bot AI, and speed-based dash modes.
• Created educational and family-friendly games such as Mathscape and Tank vs Tank, blending procedural content with intuitive controls.

Experimental Systems & Prototypes (digitalriftgames-labs.itch.io)

• Developed GUTS - Bullet Heaven Survivors, demonstrating scalable spawning, upgrade systems, and performance-aware object management.
• Built GUTS - Tic Tac Toe, a modular architecture demo featuring reusable turn-based logic and data-driven board generation.
• Designed reusable gameplay frameworks supporting turn-based logic, AI decision-making, board generation, and UI state management to accelerate prototyping across genres.

Children's & Casual Games (teammathiasgames.itch.io)

• Produced touch-friendly titles including Marvel Memory Match, Unblock Pic, Spelling Bee, Kitchen Chaos, and Fired Up Birds, focusing on accessible UX and simple, responsive interactions.
• Created cozy and idle-style experiences like Train Town Tycoon with smooth camera systems and relaxing progression loops.

Simulation & Training (dgsoftware.itch.io)

• Built the Excavator Inspection & Operation Trainer, implementing inspection workflows, cab-based controls, and scenario-driven training logic.
