Operator
I run the parts most people never see. Proxmox clusters, custom PXE boot environments, and automated provisioning through VirtFusion and Tenantos. When something breaks at 3 AM, I am the one who gets the page.
Game servers are a specialty — Minecraft JVM tuning, FiveM resource optimization, Factorio headless deployment, Space Engineers Torch integration. Players should never know how much work keeps their world online.
Recently, I have moved heavily into AI engineering: extending coding agents, building agent-native UIs, designing prompt/tool call patterns, and automating development workflows around LLMs.

Featured Projects
A live dashboard that streams the PI coding agent into the browser. Built with Bun, Hono, React 19, Tailwind v4, and SQLite.
- Project/session management with live WebSocket streaming
- Real-time tool-call display: read, bash, edit, write, grep, find, ls
- Toggleable thinking/reasoning visibility
- In-stream steering and abort controls
PI extension that brings in-process tree-sitter diagnostics and compiler-backed type checking straight into the agent context.
- Parses changed files after every edit/write and injects diagnostics
- 80+ languages via in-process WASM parser
- Go-to-definition, references, hover, document symbols
- Two-tier validation: tree-sitter instant + compiler accurate
A focused tool-suite that extends the agent with structured code search, semantic git ops, security scanning, and multi-file refactor orchestration.
- patch — unified-diff apply with auto-locate
- outline — file structure without implementation noise
- rg / find — structured code search
- test / validate / build — detect, run, and report failures
