Senior Unity/XR systems engineer building industrial real-time software that can survive delivery, operators, and AI-era workflows.
I have spent 10 years building Unity-based systems across XR simulators, BIM runtime tooling, digital-twin style authoring, robotics control, and applied AI operations.
The common thread is practical ownership: runtime structure, validation, operator context, field setup, and repeatable delivery.

Experience
10Y
Unity-based systems across education, simulation, industrial XR, BIM, robotics, and AI.
XR Delivery
4+ Rounds
Installation, live operation, teardown, and operator-facing exhibition or training support.
Industrial Runtime
BIM + Robot
Heavy geometry tooling, runtime viewers, digital twins, and live robot control bridges.
Applied AI
XR + Ops
Voice AI, orchestration frameworks, local agent ops, observability, and operator-facing AI systems.
Profile
My work started in learning content and moved into XR simulators, BIM tooling, robotics control, and AI workflows.
I do not treat these as disconnected domains. They are extensions of the same problem: building real-time systems that have to work under pressure.
That is why I care as much about structure, validation, maintainability, and field conditions as I do about implementation speed.
Working strengths
Designs around operator constraints, failure cases, and delivery pressure rather than isolated demos.
Comfortable across runtime interaction, editor tooling, geometry processing, robotics interfaces, and AI system rules.
Brings field context from installation, site visits, hardware assembly, exhibition support, and operator handoff.
Uses AI as an operating component with boundaries, observability, explicit workflow rules, and reusable runtime structure.
Strongest fit: industrial XR, BIM runtime tooling, robotics interfaces, digital-twin systems, and applied AI workflows that must survive real operators and delivery pressure.

Selected proof
Representative systems and framework work
These four projects summarize the range I want the resume to communicate clearly: industrial runtime ownership, geometry-heavy tooling, and AI systems that move past demos into operating structure.
Industrial XR x Robotics
VR Robot Teleoperation
Quest 3 to Doosan A0912 control pipeline with safety logic, calibration, and in-house Jacobian IK extension.
BIM Runtime Tooling
WatchBIM
Custom BIM hit engine, cross-section generation, 2D analysis viewer, and tool-grade camera system in Unity.
AI Workflow Framework
Multi-Agent Orchestration
Reusable role rules, review gates, launcher flow, and operating logic for agent collaboration.
AI Ops Infrastructure
Ops-Cure
Discord-native local agent operations with a NAS bridge, Windows launcher, and artifact-aware session telemetry.
Hiring fit
Senior Unity/XR systems work where runtime logic, tools, and delivery all matter together.
Industrial simulation or digital-twin roles that need geometry, operator workflow, and runtime structure.
Applied AI roles that need orchestration logic, observability, and local operations rather than prompt-only demos.
External proof
MSIT Minister Citation and BIFAN XR Beyond Reality Official Selection.
Korea Maritime Mobility Safety Expo demonstration and repeated field delivery support.
English product explanation for external stakeholders, including Lockheed Martin visitors.

Career
Recent career and major ownership
YMX - Senior Engineer, Client Team 2
Dec 2024 - Present
Industrial Unity systems, editor tooling, robotics interfaces, and exhibition content.
Built DXCenter, an authoring environment with nine EditorWindow tools, reusable mapping rules, and a cleaner runtime path for non-developer operators.
Built the Unity - Flask - RoboDK - robot pipeline for VR robot teleoperation with safety logic, calibration, and public demonstration readiness.
Extended the same control problem into Jacobian IK and real-time bridge R&D rather than treating it as a separate toy study.
Started a synchronized exhibition system that coordinates Unity visuals and hardware motion within a practical real-time window.
Sixdopamine - Project-based
2025
Applied AI XR exhibition system, Flask AI pipeline, and operations dashboard.
Designed the Flask-side AI flow and the React dashboard for Neostalgia.
Connected Whisper, GPT, TTS, Skybox AI, Meshy, GCP storage, and XR timing into one exhibition-ready system.
Recognition: BIFAN XR Beyond Reality Official Selection and the MSIT Minister Citation.
Jangheon Industrial - Seoul Office
Jun 2020 - Dec 2024
BIM visualization, geometry tooling, drawing automation, and engineering software.
Built a highway BIM 3D platform with mesh optimization, auto LOD, cross-section generation, slope labeling, minimap generation, and camera tools.
Implemented job-based geometry handling for heavy BIM data and 2D section analysis workflows.
Built a WPF road-design drawing automation system using MVVM, MySQL, and CAD entity generation.
These three roles show the main spine of my work: runtime structure, tool ownership, geometry-heavy systems, and AI connected to real operations. The recent AI track is strongest where orchestration rules, local agent ops, and runtime observability come together.
