Two research projects on AI that recognizes 3D shapes, and a team product that turns furniture designs into factory data.
Product ViewAI that reads 3D models and designs processing strategiesWe established an end-to-end workflow—from recognizing machining features to generating Fusion CAM processes and verifying the final results.ResponsibilityWe developed the geometry analysis, machining strategy, and Fusion integration components; the digital twin component was used solely for visualizing the results.9 typesMachining feature to identify · Include stock
Research renderAI that recognizes furniture panels and calculates resizing rulesPanels are identified and size adjustments are calculated using parametric formulas, enabling real-time design and ordering via the web.ResponsibilityWithin the team, I was responsible for AI-based panel recognition and the formulation of mathematical equations to calculate changes in panel size and position.15 typesPanel types recognized by AI
Product ViewWedraw Pro, from furniture design to productionThe SketchUp design was output as BOM, label, drawing, and processing code and checked on the web.ResponsibilityWithin the team, I led the output of manufacturing data and production integration, along with the initial development of technical drawings and procurement processes.4 typesBOM, label, processing drawing, processing code output
Project Archive
Development work I took on beyond the key projects.
Service monitoring and error trackingThe system detects not only server status issues but also failures in processing invoices and notification messages; we have already resolved six such operational issues.ResponsibilityI developed the entire system—from defining monitoring criteria and collecting/notifying errors to building the administrator console.View Project
VODA architecture redesignRebuilt event collection, aggregation and page capture for the new architecture and fixed the analytics screens' timeouts.ResponsibilityI developed coordinate collection, message processing, the refiner and the crawler.View Project
VORY-Q personalized recommendationsDesigned a service that picks recommended products for each customer from visit and purchase records and shows them in the store.ResponsibilityI designed the data flow, API, database and recommendation structure and developed the statistical recommendations.View Project
Scene change playerMarks scene changes on the seek bar and handles preview, scene navigation and segment saving on one screen.ResponsibilityI developed every player feature apart from scene detection.View Project
OpenCAD: free online CAD and 3D viewers
All tools and usage instructions.I build a 2D CAD for opening, editing and saving DWG/DXF drawings, and viewers for STEP/SketchUp models and NC toolpaths. All are free personal open-source projects that run without installation, and the 3D core the viewers share is public too.
OpenCAD DWG·DXFA free online CAD editor for opening, drawing, editing and saving DWG and DXF files without installation or sign-up. Measure distances, angles and areas, and export PDF, PNG or SVG..dwg.dxf
OpenCAD STEP ViewerThis is a free viewer that opens STEP·STP 3D CAD files in the browser without installation. You can check the assembly structure and part properties, measure hole diameters and distances between faces, and look inside with section and exploded views..step.stp.p21
OpenCAD SketchUp ViewerThis is a free viewer that opens SKP files saved in SketchUp 6-2026 in your browser. You can look through tags, materials, groups and components, tour the space with scene playback and walk mode, and measure distances and angles..skp
OpenCAD NC ViewerA free NC viewer for checking 3D toolpaths in G-code, Heidenhain (Klartext and DIN/ISO) and panel machining files (woodWOP MPR, WangShi PGI, KDT XML). You can trace code lines together with their moves and replay the machining sequence while watching the stock being cut. Lines to check before the program goes to the machine are flagged as warnings..nc.gcode.ngc.h.mpr.pgi.xml
Manufacturing Software Development Notes
All notesNotes on what I worked through while developing AI, CAD/CAM and furniture manufacturing software. My role and results in each project are in the cases linked from each note.
As an undergraduate researcher, I worked on reinforcement learning, clothing classification, and virtual try-on. The images below were made by running the public code.
A graph model for generating TSP routes using reinforcement learningI implemented a graph-based TSP search program that uses reinforcement learning to select the next city to insert into the route.ResponsibilityI connected the graph environment and training loop with the rules for inserting cities into the route.Step 2AI city selection + heuristic route insertion
A model for classifying clothing photos with ResNetI trained a model to classify K-Fashion photos as dresses, outerwear, trousers or tops and analyzed errors for each class.ResponsibilityImplemented transfer learning, class-based sampling, and confusion matrix evaluation.4 typesClassification: Dresses, outerwear, pants, and tops
Virtual Try-On App for Clothing on Photos of PeopleI built the Android-to-server workflow that returns a virtual try-on image after the user selects a person photo and a garment.ResponsibilityThe input preprocessing pipeline for the public model has been integrated with a Flask API and an Android application.Step 3Pre-processing → Generate "try-on" image → Return to app

Introduction
I want to make people's work and daily lives a little easier with AI that can be applied in the real world.
In the research phase, we implemented methods to analyze geometry and learn design rules. In the product phase, these were applied to design modifications, the generation of manufacturing data, and pre-production verification. During operation, we collected processing results and error logs to identify overlooked issues and address their root causes. We hope that tools like these will reduce the burden of re-entering design information and minimize trial-and-error during the machining process, enabling even small-scale manufacturing workshops to leverage accumulated technical expertise.
