Case studies
Freelance Developer Site with a Project CMS
A homepage and a small management tool in one, so finished projects can be written up once, published in Korean and English, and inquiries can be handled in one place.
Label Print Sheet Generator from Marketplace Order Exports
Reads order spreadsheets whose formats differ by marketplace, lays out each label according to the buyer's chosen options, and produces 300 dpi PSD sheets ready for the print shop. Orders it cannot process are listed separately with the reason.
Development Project Schedule Management System
Built a desktop client and API server so a manufacturing company's development schedules live on one shared Gantt timeline instead of in separate per-project files.
Desktop Tool for SEM Image AI Training and Inspection
A desktop application that lets semiconductor SEM imaging models be prepared, trained and run without touching the command line. Data straight from the measurement tool can be opened and labelled, training settings edited, and inference results reviewed alongside the images, all in a single window.
Operator Console for a Collaborative Robot Barista Cell
An in-store console that merges kiosk orders and staff-entered orders into a single queue, drives a collaborative robot over Modbus TCP, and keeps extraction progress, consumables and alarms on one screen.
Tire Road Noise Prediction Tool
A Windows desktop program that loads per-wheel measurement files and stored vehicle data, computes the cabin noise spectrum, overlays it against reference measurements for comparison, and exports the result to a file.
Barcode-Driven Outbound Shipping Manager
A Windows desktop program that loads purchase-order spreadsheets, tracks the remaining quantity for each item, and decrements it with a timestamped record every time a barcode is scanned at the packing station.
Simultaneous Permittivity and Temperature Acquisition
An LCR meter and a thermal camera that run on their own, unsynchronised cycles are acquired together in a single program, so permittivity and specimen temperature can be followed on one time axis and exported as CSV.
Structural Displacement Monitoring Desktop App
Replaced the manual work of pulling displacement data out of a monitoring database and computing it by hand with a resident desktop app that reads each new measurement cycle, derives tilt and inter-story drift angle, and grades them against fixed criteria.
Clinical Data Quality Evaluation Desktop Application
Seventeen clinical data quality analysis modules, each developed separately by a different researcher, were integrated into one desktop application with a single input format, a single run procedure and a consistent result view, so that running every metric takes two CSV files and no Python environment.
Real-Time Weld Bead Width Prediction
The application acquires CCD camera images and spectrometer readings while a weld is in progress and feeds both into a neural network that predicts bead width on screen. When a run finishes, the video, the spectra and the predicted widths are written out for the same time window.
Dissolution Testing Data and Equivalence Analysis Tool
A Windows program that calculates dissolution rates from instrument export files, stores them on a server together with the test conditions used, and later overlays profiles from different runs to judge equivalence with the f2 similarity factor.
Delivery Order Desktop Client
A Windows desktop client that polls for incoming delivery orders and announces them with a sound and an always-on-top alert, so staff can accept, cancel, complete and print an order without leaving the app.
2D LiDAR Detection Area Setup and Monitoring Tool
A Windows tool for industrial LiDAR safety sensors. Instead of typing coordinates, technicians drag the detection area into place on top of the live scan, and every scan point is colored by whether it falls inside or outside that area.
Before-and-After Photo Comparison and Measurement Viewer
Replaced eyeballed before-and-after photo comparisons with a single window that tiles the photographs at a shared zoom level, measures distances in centimeters and angles in degrees, and exports an annotated image.
Wireless Temperature Sensor Monitoring Display
A desktop application that pulls wireless temperature sensor readings from the cloud, keeps them on a display at the site, and raises an on-screen and audible alert whenever the reading leaves the configured range.
Time-Resolved Spectroscopy Acquisition Software for ICCD Cameras
Time-resolved measurements used to mean retyping the gate delay and re-arming the camera for every point. This application runs a prepared list of timings on its own and stores the camera settings alongside the frames, so a saved file carries the conditions it was taken under. Images, wavelength-calibrated spectra and export all live in one window.
Multi-Channel Acquisition and Monitoring for Combustion Testing
A desktop program that gathers the pressure, flow and temperature channels of a combustor test rig onto one screen and derives the quantities an operator needs to judge the operating point, such as equivalence ratio and laminar flame speed, while the test is running.
