Head of Tech at CamperMate. Open-source creator. Building typed trading infra in Rust, developer CLIs in Go, native React Native modules, AI-assisted video tooling, and personal finance tools in Python — plus a handful of Claude Code plugins and MCP servers.
Interested in the confluence of electronics and mechanical engineering (drones, eskates, and ebikes). Currently obsessing over Rust + OpenAPI codegen, agentic developer tooling, and shipping SaaS that doesn't feel like a framework.

🚲 A test-driven, code-as-data engine for "will this part fit my bike?" Rear shocks, forks, ebike motors & batteries, drivetrain, brakes, cockpit — deterministic fitment checks that return pass / warn / block with reasons, never a black-box yes/no. The interface/adapter problems (BB, freehub, rotor, headset) resolve to native / needs-adapter / incompatible. AI and guided measurement fill the frame data manufacturers don't publish.

📐 True-3D technical drawings in SVG — ~180 lines, zero dependencies. Rotate → project → depth-sort → paint. Drop in a glTF/OBJ mesh and it extracts the feature edges into a rotatable, themeable, crawlable line drawing — no WebGL. Fills the empty niche between heavyweight 3D engines (hostile to linework) and dead pseudo-3D toys (no text). The whole page draws itself.

🦀 Typed async Rust client for the Interactive Brokers Client Portal Web API — with HTTP, CLI, MCP, and TypeScript surfaces all generated from the same vendored OpenAPI spec. Five ergonomic surfaces, one command to regenerate them all when IBKR revises the spec.

📈 Autonomous, multi-agent portfolio fund for Interactive Brokers — the companion to bezant. Nine deterministic TypeScript agents handle allocation (HRP / Black-Litterman), risk, tax, and execution, with validation-first trading, hard caps, and data-sanity gates. Runs standalone or under any scheduler; your real book stays in a gitignored file.
