I like building things people actually use. Below are the products I’m working on and a few games I made for fun. All of them are live, so try them.

Things I’m building

Works in progress

Furl’s home page: send one link, get everything back, sorted

Furl

Work in progress

One link to collect documents from clients. Each file is read and ticked off a checklist, and reminders chase only what’s missing.

AI reads each upload; plain rules check the quantities (“one W-2 per employer”, “12 months of statements”). Teams, roles and reminder emails.

Shape’s home page: turn the file you get into the file you need

Shape

Work in progress

Clean up a messy spreadsheet by saying what you want, then rerun the same cleanup on next month’s file.

Runs DuckDB in your browser: a million rows, and the file never leaves your computer.

Redact’s home page: redact documents privately

Redact

Work in progress

Black out names, SSNs, account numbers and other personal details in PDFs and images, then download the redacted copy.

Finds names, SSNs and account numbers with OCR and a name model, entirely in the browser: the file is never uploaded.

Shape Media’s home page: every image, ready for wherever it’s going

Shape Media

Prototype

Get a batch of product photos ready for Instagram, Amazon, Etsy and your website at once. Next week’s batch is one click.

Image recipes on Cloudflare Images, with credits and a site-wide daily budget so a public demo can’t run up the bill.

Just for fun

Games and toys

Rung: a daily word ladder

Rung

A daily word ladder. Change one letter at a time, every rung a real word, and reach the top in as few moves as you can.

Live presence over WebSockets on a Durable Object, push notifications when the new puzzle drops, and usage tracked in Buoy (below).

Koi World: a pond with koi, lily pads and floating lanterns

A shared koi pond. Feed the koi, float a lantern, or swim as a koi yourself with everyone else who’s there.

Songbird Automaton: a red mechanical bird on a wooden cam cabinet

Real cams and gearing, with the drive train explained as it moves.

Behind the scenes

Tools for the projects above

Buoy

Private dashboard

My own analytics for every app I ship. Apps send events from their servers, with no third-party scripts and no cookies on anyone, and Buoy answers “is it growing, and what does it cost?”: funnels by where people came from, with the cost of each step.

Every event is written twice: to D1 for the dashboard, and streamed into an Iceberg table (Parquet files on R2) that’s queryable with SQL, so an app can outgrow D1 without a migration. Rung reports to it.
