A few things
I’ve been making.

An imagined cabin. Someday, perhaps.

I’m Brian. I’ve spent thirty years building for the web. These days, I’m making apps for music, play, and whatever catches my curiosity.

Independent apps for iPhone & iPad

Astronomy · iPad

Ten Thousand
Skies

The same sky.
A different millennium.

Choose a place on Earth and a year from 10,000 BC through AD 10,000. See the sky above it.

A way to explore astronomy through time and place, from the sky over ancient Giza to the stars of a distant future.

Experiments & other work

The apps are part of the story. I’m also exploring reading tools, simulations, and new ways to work with AI.

Here’s the rest of the workbench.

Pimola

In Beta

A calm, private way to split a restaurant bill — scan the receipt, tap who had what, get exact totals. Entirely on-device.

A close friend suggested the idea. It’s a busy market, so I wanted to take a different approach: simple, intuitive interface, and reliable receipt scanning.

Wonderdeck

In Progress

An enchanted deck of cards for tiny games, story sparks, and silly prompts — the kind of thing you pull out in a waiting room or at the dinner table.

I wanted the tactile feel of a real, magical deck instead of another list of prompts — cards you flip, fan, and keep.

Clearing

In Progress

A calm decluttering app that hands you one small zone and one decision at a time, gently biased toward letting things go.

Decluttering stalls on decision paralysis. I wanted an app that works like the executive function you wish you had — narrow the choice, auto-advance, keep moving.

AI-assisted website analysis for content, technical, and competitive review.

Most website audits are either too shallow to be useful or too expensive to run often. I wanted to see whether AI could make deeper review self-service, repeatable, and genuinely useful.

Book Club

In Testing

A reading companion that goes chapter by chapter — talk about what you just read and collect AI-written summary cards as you go.

I wanted to see whether AI could deepen reading without spoiling it: present only for the chapter you’re on, never racing ahead.

Wall St.

Functional Archive

A multi-agent stock market simulation with real market data and inter-agent communication.

I wanted to understand how agents behave when they have different roles, goals, access to shared information, and the ability to communicate with each other.

F1 Replay

Functional Archive

A browser-based replay of past Formula 1 races, reconstructed from public timing data.

I wanted to explore data modeling. I knew the F1 data feeds were extensive. Could they rebuild past races? It turns out: Yes.

AdjacentPath

An AI-driven questionnaire and report for professionals considering a career change — reframing experience, preferences, and constraints into possible paths.

Drafterly

An AI-assisted content workflow for over-stretched marketing teams. Helps move real work through planning, drafting, review, revision, and publishing while preserving context and voice.

Auto-QA

Automated, highly configurable event and agent driven toolset for testing online web apps.

T-shirts

Automated t-shirt idea generator with detailed text and layout editing tools. Exports to drop-ship vendor formats.

PageAudit Clarity

A streamlined version of PageAudit for visual and content evaluation of a single URL.

Competition Tracker

Monitors and analyzes online communications sources for a user-defined list of companies. Output is a weekly email digest of changes and analysis.

Done By EoD

A lightweight project management tool with an AI project manager as a first-class interface, not a chatbot bolted onto the side.

Site Sight

A tool that gives AI “eyes” on a website as a user experiences it, including visual design, layout, motion, and interaction.

A little about me

Thirty years in.
Still curious.

I’ve spent most of my career building websites and digital systems for organizations with complicated needs. Lots of content, lots of people, and problems that rarely fit neatly into a project plan.

AI pulled me back into hands-on building. I now work with Claude Code and Codex to turn ideas into software, including the iPhone and iPad apps here.

I’m still learning. This is where I collect the work as I go.
