Shipped & Running

Every site below is live, in production, on my own infrastructure. Click through — nothing here is a mockup.

the-chamber.app — trading platform
PROJECT 01 · Full-stack Platform
The Chamber App
the-chamber.app

The platform itself — 15+ features: trade logging with bulk import, performance analytics, an AI mentor grounded in an SMC knowledge base via RAG, chart analysis from screenshots, a psychology journal, economic calendar, and paid-tier auth.

The Chamber
chamber.trading

Cinematic 3D landing page for the trading platform I built — an interactive boot sequence, a Three.js orbital scene, and an in-page demo where visitors talk to the AI mentors before joining. Hand-written vanilla HTML/JS, no framework.

[ 02 ] The Bot Fleet

Four Agents, Always On

A fleet of Claude-powered assistants I architected — shared Python core, Supabase-backed memory, per-bot personalities — running 24/7 on a Mac mini with heartbeats, watchdogs, and self-healing schedulers.

What This Portfolio Proves

Concrete systems, not adjectives. Everything listed ships from one person's desk.

01
Full-stack production apps, solo
Next.js + Supabase + Claude API with pgvector RAG pipelines, auth, paid-tier routing, and Postgres migrations.
02
Safe agentic systems
Human-in-the-loop approval gates, allowlists, audit logs, at-most-once execution — actions are gated, never taken from model free-text.
03
macOS systems engineering
launchd fleets, root LaunchDaemons, PF firewall rules, native-messaging hosts, watchdogs and self-healing schedulers.
04
Practical LLM engineering
RAG, vision, server-side tool use, and a nightly learning loop that mines conversations so the bots stop repeating mistakes.
05
Discipline tooling that survives me
TiltGuard: a multi-layer macOS lockout (hosts, packet filter, process killer, Chrome extension) that ends my trading day after 3 trades — by force.
06
Brand & generative graphics
A frozen design system plus an automated pipeline that composites branded trade recaps from live data — PIL, HTML overlays, headless Chromium.
