AI-native software engineer — I ship production software solo: desktop, web, and edge.
I build the whole thing — architecture, implementation, verification, release — and I use AI as a force multiplier rather than a code generator. That means the interesting engineering is usually in the guardrails: the budgets, the audit trails, and the tests that let a small team move at a large team's pace without shipping something unverified.
🦀 Aegis — deterministic execution harness for AI agents
Agents are non-deterministic. The harness around them shouldn't be.
- Hard budgets — tokens, steps, and wall-clock are ceilings enforced before work happens, not after
- Byte-exact replay — every step journals to SQLite, so any run can be reconstructed or resumed from where it crashed
- Shadow-Guard — mutating tool calls are intercepted and recorded in a dry-run before they touch anything; unknown tools fail safe, classified as mutating
- MCP server — exposes its own capabilities as tools, so any MCP client can drive it
- AST-aware compaction — Tree-sitter keeps every signature, type, and doc comment while eliding bodies. Measured across my own codebases: 61% average token reduction, 89% peak
- Runs in a browser — the real engine compiled to WebAssembly, ~137 KB, no server or API key

🌍 WorldFrame — desktop worldbuilding app for writers
A native app for authors managing large fictional worlds. Shipping at v1.0.15 across macOS (universal) and Windows, with signed builds and an auto-update channel wired to a public release manifest. Offline-first, and an explicit no-forced-AI design stance — writers own their words.

⚡ Review Syndication Pipeline — built in a 45-minute window
A technical assessment delivered as working software rather than a mockup. Ingests messy multi-source Korean reviews and runs the real hard part end to end: translation, de-duplication, and clinic-name normalization into a published demo page. Live demo →

My portfolio is a classic Mac OS desktop running in the browser. Every icon opens something real — including Aegis itself, executing live via WebAssembly.

- Verify, don't assert. A green summary I wrote myself isn't evidence — exit codes and reproductions are.
- Fail safe. An unrecognized tool is assumed dangerous. A typo in a safety flag is an error, never a silent downgrade to something permissive.
- Document the trade-off, not just the code. The decisions worth writing down are the ones where the obvious fix would have made things worse.
