Career Summary
7 Years of Experience · 3D Graphics / Data Engineering / System Architecture
- ▸ Led projects across diverse domains including Construction/Civil Engineering, Media Art, Public Data, and E-commerce.
- ▸ Winner of the Seoul Big Data Contest Excellence Award (2023)
- ▸ System Architecture & Backend Development in Japanese SI Environment (2025 - Present)
What I'm Doing Now
In a Japanese local SI environment, I am analyzing various legacy systems, migrating them to modern backend architectures, and developing new APIs. Even in environments with insufficient documentation, I lead projects by reverse engineering code to understand business logic.
Availability
Currently employed, but always open to interesting technical challenges and collaboration proposals.
Engineering Philosophy
Root Cause Analysis
I reject superficial fixes that focus only on symptoms. I pursue and isolate the root cause at the system level to prevent recurrence.
Automation First
Repeated human errors indicate a lack of systems, not individual mistakes. I design structures that minimize human intervention by building scripts and pipelines.
Performance by Design
Instead of tuning after completion, I build structures that guarantee performance by considering I/O bottlenecks and memory lifecycles from the design stage.
Career Timeline
Japanese SI On-site Project. Proving adaptability by identifying essential system structures and designing stable backends amidst unfamiliar domains and intertwined legacy code.
Samsung C&T DX Project. Built core logic for applying 3D technologies to large-scale industrial infrastructure platforms.
Seoul Big Data Contest Excellence Award. Crossed domain boundaries by analyzing urban data using Python and AWS.
Reduced image processing latency from 206ms to 13ms in a Media Art project, confirming that performance is determined at the design stage.
Fell in love with the possibilities of bio-digital interfaces while building a system to control VR spaces in real-time using brainwave signals.
Realized that 'code without structure collapses' while initially designing a 3D Web Viewer framework for construction and civil engineering.
Skill Matrix
Architecture & Backend
- Java / Spring Large-scale traffic processing and enterprise microservice design
- RDBMS Query tuning, index optimization, and zero-downtime data migration strategies
- Kafka / Redis Building asynchronous messaging pipelines and in-memory caching architectures
Scripting & Automation
- PowerShell OS-level system control, automation tool development, and massive data preprocessing scripting
- CI / CD Constructing zero-downtime deployment pipelines utilizing GitHub Actions or Jenkins
Graphics & AI
- WebGL / 3D Matrix transformations, shader programming, and frontend 3D rendering optimization
- Python Data analysis, mathematical algorithm implementation, and AI model integration interface development
Interests
Outside of code, I am highly interested in work that lies at the boundary of technology and art. My participation in media art projects was an extension of this, and I find joy in creating moments where people experience new sensations through technology.
