- Built a custom code-execution engine in Go with isolate sandboxing for secure, resource-limited execution of untrusted Java across multiple JDKs (17 / 21 / 25), with sub-300ms cold starts and SSE result streaming.
- Deployed the full stack on a single VPS: Spring Boot auth (JWT, PostgreSQL), a Cloudflare Worker edge proxy, and a Vite SPA playground, with end-to-end sandbox isolation verified.

Things I've designed and shipped on my own.
- Built a 2D CPU rasterizer from scratch in Go: stdlib-only, hand-rolling the geometry, adaptive Bézier flattening, and scanline fill/stroke math with analytic antialiasing.
- Architected in phases toward an interactive engine: PNG rasterization → SVG export → real-time windowed rendering (Ebiten), designed to grow into a GPU-backed pipeline.
