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. By deeply analyzing legacy code and existing systems through reverse engineering, I grasp complex business logic and steadily lead projects to success.
Availability
Currently employed, but always open to interesting technical challenges and collaboration proposals.
Engineering Philosophy
Root Cause Analysis
Rather than superficial fixes, I aim for structural solutions that trace the root cause at the system level and 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. Quickly analyzing new domain requirements and existing system structures to design stable and scalable backend architectures.
Samsung C&T DX Project. Built core logic for applying 3D technologies to large-scale industrial infrastructure platforms.
Seoul Big Data Contest Excellence Award. Built large-scale urban data analysis pipelines using Python and AWS, achieving significant technical outcomes in a new data domain.
Analyzed and redesigned the bottleneck in the image processing pipeline, significantly reducing processing latency from 206ms to 13ms.
Built a real-time VR control system based on brainwave signals, gaining experience in applying novel interface technologies to practical use cases.
Designed a 3D Web Viewer framework for construction and civil engineering, realizing the importance of structural architecture design for sustainable services.
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
