freelance builds

Websites, web apps and data tools. Specced, built and shipped.

Tell me what you need in plain language. I turn it into a written spec, build it with Claude Code one tested piece at a time, and hand you a live site with the code behind it.

Custom web apps & tools

From a written spec to a working app: community platforms with accounts and moderation, matching apps, image and color tools.

Seen in: Back in the Day, Guidance, Grayscale Studio, Pigment

Data dashboards & automation

Scheduled pipelines that pull data, crunch it and publish a board that updates itself.

Seen in: PropEdge

Every project is quoted after a short scope. Tell me what you need and I'll reply with a written plan and a price.

The PropEdge board: league tabs for MLB, NFL, WNBA and NBA, summary stat tiles, and filter chips for prop types

Live

PropEdge

A sports player-prop board for NBA, WNBA, NFL and MLB. It compares lines across about 20 sportsbooks and shows fair-value probabilities for each prop.

Built: a Python pipeline that pulls stats and odds, projects each player, strips the bookmaker margin to get fair prices, and publishes the board, rebuilt automatically five times a day. It measures its own hit rate and says plainly where it can't predict.

Illustration for Pigment: a grid of twelve paint color swatches with their hex codes

Live · free sign-up

Pigment

A color studio for painters. Sample any color from a photo, choose a medium and paint brand, and get a mixing recipe built from that brand's named pigments.

Built: a rebuild specified as 11 tickets, with the color math, crop geometry and sampling kept in a pure, unit-tested core. Mixing ratios come from a closeness search in Lab color space across each brand's pigments.

03 / process

How a project runs

  1. Scope

    You describe the problem. I write a spec: who it's for, what they do first, and what happens when something goes wrong.

  2. Tickets

    The spec becomes a short list of small, testable tickets, so you can see progress and change direction early.

  3. Build & test

    Each ticket is built with Claude Code, then reviewed and tested before the next one starts.

  4. Ship

    Your site goes live, and you get the code plus a README that explains how to update it.
