Featured XR / Simulation Work

Three flagship projects that best represent my Unity, XR, enterprise visualization, digital twin, and training-simulation experience.

Hikar Digital Twin VR Factory Visualization

Unity · Quest · WebGL · XR Toolkit · Live IoT/API Data

Built a digital twin-style VR factory visualization prototype with live IoT/API data display.
Created WebGL machine viewers and VR factory scenes for product presentation, training, and demos.
Integrated status panels, dashboards, indicators, charts, and interactive product manipulation.

View Case Study

Context

Internal Hikar Canada prototype for digital twin visualization, VR factory presentation, training concept validation, and stakeholder/client demos.

My Role

Main Unity Developer responsible for most Unity-side implementation.

Tech Stack

Unity, C#, Meta/Oculus Quest, WebGL, Photon, XR Interaction Toolkit, custom Unity scripts, API/live data integration.

What I Built

Individual WebGL machine viewers integrated into a React dashboard by the wider team.
VR factory setup with machines, product manipulation, training modules, and guided presentation flows.
Floating UI panels, dashboard screens, indicators, charts/text values, Quest/WebGL builds, testing, and demo prep.

Data Integration

The project started with mock/sample data and later used real/API data representing live IoT machine status.

Outcome

Working internal prototype used for stakeholder demos, training concept validation, and live-data visualization demonstration.

Media note: Original project files/builds are internal. Public visuals should use safe screenshots, representative scenes, or recreated demo media only.

DAKSH Training Simulator

Unity · PC Simulation · Serial/USB Input · Training Controls

Worked as the main Unity programmer on a PC-based operational training simulator.
Integrated actual remote-control hardware input through Serial/USB communication.
Built simulated machine/robot-style movement, dashboard UI, cameras, feedback, warnings, and deployment support.

View Case Study

Context

PC-based operational training simulator developed for a DRDO India-related training context, coordinated through a mediator/team.

My Role

Main Unity Programmer. I handled around 90% of Unity-side implementation, including simulator behavior, UI/dashboard logic, input integration, deployment, and post-deployment changes.

Tech Stack

Unity, C#, PC build, UGUI, Serial/USB communication, joystick/button hardware input, custom scripts, camera systems, animation, physics/collision response, and 3D model setup.

Important Clarification

The simulator used actual training remote-control hardware for input, but did not control the real machine. Unity visualized the simulated response on screen.

Outcome

Working PC simulator delivered and used for training/demo and stakeholder presentation, with additional support after deployment.

Media note: The portfolio video is an actual trailer/demo prepared by the project team for presentation to DRDO India. Sensitive implementation details are kept general.

Würth Collaborative VR Training / Presentation Prototype

Unity · Photon · VRTK · Multi-Platform VR

Built a collaborative VR prototype for product/machine presentation, training concepts, and remote discussion.
Supported Quest, PC VR, desktop PC, and Android through a prototype-level multiplayer flow.
Enabled users to join a shared virtual space and inspect 3D products/machines interactively.

View Case Study

Context

Internal Würth India prototype for enterprise collaboration, training concept validation, product/machine presentation, and stakeholder demos.

My Role

Main Unity Developer with ownership responsibility for prototype implementation and demo preparation.

Tech Stack

Unity, C#, Photon, VRTK, Quest/PC VR, desktop PC, Android builds.

What I Built

User avatar/player presence and room/session joining using Photon.
Object grab, rotate, inspect, navigation, movement, UI panels, and presentation flow.
3D model import/setup, performance preparation, builds, testing, and stakeholder demo support.
