Client systems, products I'm building, and tools that came out of my own work. Each started with a problem I wanted to understand and solve.
Client work · Sports data
On a small development team, I built and expanded Python data pipelines covering 18 soccer leagues and 10,000+ player profiles. The work automated collection and reconciliation previously handled in Excel, with admin tools the owner uses daily.
Trading systems · In development
I design the architecture and direct AI-assisted development of this Python trading system, focusing on cash controls, interrupted orders and testing. An offline full-history computation improved from 177.2 to 34.7 seconds with identical results.
After about four weeks of trading, I took it offline to develop scheduled operation and bulk-order workflows.
Construction software · Alpha
A product I co-founded to help construction teams record safety observations and follow through on corrective actions. I lead the engineering across web and mobile, including encrypted offline report drafts and company-specific access to reports. My partner and I are testing the alpha.
Creative tools · Live app
My sister is a textile designer. Her requirements shaped this browser tool for arranging artwork into straight, half-drop and brick repeats. I directed the AI-built implementation, with editable project files and PNG exports designed to complement her work in Photoshop.
Coding-agent evaluation
I built a benchmark harness and analyzed 400 scored implementations across eight configurations to investigate how coding agents work together. Hidden tests, isolated workspaces and token accounting let me compare implementation quality and resource use.
Teaching tools · Code Fellows
When Code Fellows needed to migrate its teaching materials, I built a Python tool to convert Google Slides into reveal.js presentations. It handled more than 100 decks and saved an estimated 800 employee hours, according to my manager.
Developer tools · Codex plugin
A plugin I use throughout my frontend work. It gives coding agents a curated library of design references, then guides a review of working controls, mobile layouts and accessibility. I built the retrieval and audit workflow around existing reference material.
