Twenty years building systems that carry real load — a wildfire map serving 1M+ people a month, lakehouse pipelines, trading research held to walk-forward validation, and a storefront that takes payments. Available for project work.
Lakehouse and warehouse pipelines, schema design, and migrations run so they are reversible and tracked — not applied by hand and hoped over.
Scheduled pipelines, ingestion from messy third-party sources, and the monitoring that tells you when a feed goes quiet before a stakeholder does.
Dashboards and geospatial interfaces people actually use — including a live wildfire map serving over a million users a month.
Connecting systems that were never designed to talk: payments, CRM, ERP, analytics, and government or vendor data feeds.
Agent infrastructure, retrieval and embedding systems, and LLM workflows built to be evaluated rather than demoed.
Storefront builds and operations on Shopify and custom stacks — catalog, payments, fulfillment, and the analytics behind the funnel.
Sole engineer responsible for WFCA's entire digital ecosystem.
Research bench for systematic strategies across equities, commodity ETFs, and crypto. ~138K lines of Python, 1,732 tests, CI-enforced validation rules. Deflated Sharpe Ratio for multiple-testing bias; 3-fold walk-forward as the promotion gate; alpha over buy-and-hold, not raw profit. Research and paper trading only — no live capital.
Automated search over a 72-architecture parameter space, then a forensic audit that invalidated its own headline result: the top strategy's +505%/yr came from indexing up to 6 candles into the future — with the peek removed it returned −77%. Rebuilt honestly to +55.7% over 4 years, then reported out-of-sample underperformance against buy-and-hold and declined to promote it.
Persistent cross-session memory for AI coding agents. Semantic + full-text hybrid search via PostgreSQL, pgvector, and local embeddings. REST API + MCP server.
Local-first AI coding agent with 10-phase autonomous delivery pipeline. Multi-backend LLM support (local GGUF, OpenAI, Anthropic, vLLM, MLX). 1024+ tests.
Built and run a live Shopify storefront selling custom apparel and home decor — theme development, product and inventory operations, payments, and the analytics behind it. A shipped commerce build rather than a demo: artofmetazen.com.
Cross-platform quality hooks for AI agents and git. Security scanning (OWASP), simplicity checks, naming conventions. Supports Claude Code, Codex, Gemini.
