A location-based spatial world built over real-world geodata (OpenStreetMap + Copernicus GLO-30 elevation).

The work includes custom spatial coordinates and hierarchy, compact typed-array transport, terrain representation and streaming, a sparse-octree object layer for placed voxels, voxel rendering, and LOD.

This is also where I'm leaning on AI-assisted implementation the most, while still designing the core system architecture and representations myself.

An undergraduate research project extending SCALE-Sim with PREMA (HPCA 2020), a preemption-aware multi-task scheduling algorithm for neural accelerators.

The implementation adds task scheduling, runtime prediction, checkpoint/resume, and mid-layer preemption to the simulator.

A from-scratch, user-level ELF64 loader, demand pager, and cooperative thread runtime for x86-64 Linux.

Written as a programming test for admission to a KAIST research lab, with no starter implementation. It builds process startup state manually, implements SIGSEGV-driven demand paging and cooperative user-level scheduling, and transfers control directly into loaded binaries.

▶ Gameplay video

A keyboard rhythm game inspired by DJMAX, originally written in Flash and later revived and ported from ActionScript 2 to ActionScript 3.

Along with the game itself, it includes a note editor and configuration tooling.

My first long-running software project, started in middle school.

A widget-based desktop launcher built with Flash/ActionScript 2 — widgets snap to a grid across multiple pages, each with its own settings, inside a shared launcher UI.

It began as a quicker way to search the web and gradually grew into a small personal software environment.
