Projects

Web applications, connected equipment, and experiments along the way.

Currently Building

Exploring how software connects to PLCs, robots, and the equipment around them.

Personal project· In progress

ROS2 Industrial Robot Cell Integration

Self-Directed Individual Project

Taking the PLC and real-hardware integration I've already done and building a ROS2 control layer on top of it.

Completed foundation

PLC-to-Neuromeka real-hardware integration
CC-Link handshake reasoning
Multi-dock sequencing and servo loading-dock coordination

Planned next

ROS2 control layer
Orchestration and state machine
Timeout, fault, and recovery handling
Later perception and edge-AI integration

A solo project I started during self-study time, using the training facility's shared hardware. The ROS2 control layer and everything after it is still ahead.

RUTA40 Vehicle Control Interface

Frontend UI & API Integration

React UI and HTTPS control integration used to operate a door-lock function on a real vehicle, including debugging across UI, API, server, embedded-module, and physical-actuator boundaries.

Completed foundation

React control interface and real-vehicle integration
Cross-boundary diagnosis from UI command to physical response

I built the React UI and its API integration. The embedded team built the door-lock module, and the backend team built the HTTPS control API.

Professional work

Daegu Smart City Dashboard

Frontend Integration & Visualization

Frontend integration and visualization of operational APIs and real-time streams for the Daegu Smart City Challenge.

Completed foundation

Operational API and stream consumption in the frontend
Visualization and interface behavior

I built the frontend integration, visualization, and UI behavior. The APIs and real-time streams came from senior and backend engineers.

Professional work

Internal Attendance / HR Product (몰입도)

Frontend to Full-Stack Contribution

Internal attendance system where I turned real workplace rules into application logic: active-session checks, multiple work and break periods, and overnight shifts.

Completed foundation

Prevent duplicate clock-in and reject clock-out without an active session
Support multiple work and break periods
Use 06:00 as the operational workday boundary for overnight work

I worked across the frontend, Koa backend, and MySQL layers of this internal system as part of the company's development team.

BambooChat

Self-Directed Developer

A chat and study app for my class, built with FastAPI, WebSocket, and SQLite and used daily by all 22 of us.

Completed foundation

LAN messaging with FastAPI, WebSocket, and SQLite
Used by the full class of 22 classmates

I started it outside the curriculum and run it for my class. A classmate contributed the first chess implementation through a pull request.
