Creative systems thinker building at the intersection of simulation, AI tooling, and developer experience.
I write Java and React myself; for everything else (C# .NET, Rust, Python) I work with Claude Code as a pair-programming partner. The result is one person shipping at a scope that normally takes a team.
StockSim — Realistic stock market simulator
C# .NET simulation engine + Electron/React UI. ~48 000 LOC, 530 tests, 18 interacting market systems (monetary policy, supply-chain propagation, options market with full Greeks, meme-stock dynamics, a regulator that flags suspicious trading).
Claude Token Tracker — Local Claude Code cost dashboard
Tauri + React. Parses Claude Code telemetry on disk, persists to SQLite, renders daily cost, per-model breakdown, cache-hit rate, peak-hour heatmap, monthly projection. Fully offline. 3.9 MB installer.
Claude Console — Desktop GUI wrapper for Claude Code (Phase 1 prototype)
Electron + React wrapping Claude Code as a real PTY. Multi-session tabs, file tree, mode selector, approval queue that lifts (y/n) prompts out of the terminal, diff viewer, agent monitor. Phase 2 is on hold — learnings are feeding into CodeBrain below.
CodeBrain — MCP server that Claude Code uses as a sub-agent
Local inference backend (Qwen-Coder 14B via Ollama) exposed as MCP tools. Claude Code delegates bulk work (content generation, polish, boilerplate) to save context window and rate-limit budget, while keeping reasoning for the hard parts. Think Claude-offloader, not Claude-replacement. Phase 2 live with batch_generate, polish, and .brain/context.md passthrough.
Spec-Driven Claude Development — Methodology framework for AI-collaborative projects
User-level CLAUDE.md plus a companion methodology doc. Codifies how I actually work with Claude: context-hygiene rules, three-tier decision autonomy, state-file hygiene that scales with project size, mini-audit and milestone checklists. The written scaffolding that keeps multi-session projects coherent when one of the collaborators has no memory between them.
- Native: Java (Spring) · TypeScript · React · NoSQL
- With AI partner: C# · .NET · Rust · Python · Electron · Tauri
- Tooling: Claude Code, MCP, local LLMs (Ollama / Qwen-Coder), SQLite, WebSocket, ONNX
Iterating on SDCD with real project use, pushing CodeBrain into its next phase, and exploring what it really means for one developer to work effectively with an AI teammate on non-trivial systems.
