A few of the decisions nobody asks about.

Real details, from real, shipped tools

6,585 formulas

Why these numbers matter
Every formula is a typed value in the build script, not an eyeballed guess. The whole book downloads once, then runs with zero network calls, so it opens the same on a plane as it does at a desk.
Typed and exact, not vibes.
GROUP 3 100% new

T Theo Inquirer
What “100% new” tracks
The tool remembers the last several rounds of groups, so a fresh trio is never a coincidence, it's the freshest match it could find.
Scribe writes, Speaker talks, Inquirer asks. One marker, three real jobs.
P(A|B) = P(A∩B)P(B)
The book's read-aloud says, word for word
“P of A given B equals the fraction P of A intersect B over P of B”
Every fraction stacks on screen, and the read-aloud speaks the same math, not around it.

Probability & Matrices

Course textbook · 25 sections · grades 10 to 12 · one HTML file

Every choice in this book is backed by something, not a guess. Before writing a single section, I pulled research on what actually keeps teenagers engaged with material like this. I scraped it, synthesized it for the patterns that kept showing up, the dos and don'ts, and used those as guiding principles for how the book reads, not just what it teaches. When I do not know something for certain, I look it up. I would rather spend an hour confirming a fact than ship a guess.

Grouper

Classroom tool · in daily use · one HTML file

Built to run 3 Minds, 1 Marker, the daily random-grouping routine from Building Thinking Classrooms, without losing five minutes to counting off by threes. Paste today's roster, pick a group size, project it. Groups are genuinely random, but never a repeat. The tool remembers your last several rounds and builds the freshest mix it can find, so the same two students are not stuck together again by bad luck while a third never gets picked.

Wildcard

Icebreaker · 190 questions · one HTML file

An icebreaker, not really a party game. I built it to open class every so often. The questions started as an odd habit: I kept hearing genuinely good ones on podcasts during my commute, and noticed they landed better with my students than the usual icebreaker deck ever did. So I built a way to scrape more of them from transcripts, then rewrote the best so whoever spins can actually answer, not just the celebrity who was originally asked. Filter by podcast or by vibe, and pick more than one of each. Most icebreaker apps make you choose exactly one category; this one does not see why you should have to.

Color Companion

Color matcher · full marker set · one HTML file

Built for myself first. I love coloring, but I used to stand in front of a wall of markers with a reference photo, guessing, then watching the finished piece come out wrong. So I swatched every marker I own and built a matcher instead. Point it at any color and it ranks the closest real markers in the set. No more guessing.

Ask the Turtle

Brand system + live website · for a Boston consultancy · one client

The full identity, in narrative form, for a nonprofit-fundraising consultancy. Navy is the anchor (used instead of black). Lime is the single accent, one pop per view. The listening rings, three concentric ripples in lime, sky, and teal, literalize the brand's promise to listen first. I built the whole system, the mark, the type, the voice guide, the templates for proposals and reports, and every asset, then built the live website too.

My favorite page on the site was my idea, start to finish: a free Tools page with working fundraising calculators (a gift range chart, an ask-amount suggester, a retention and ROI tool) that visitors can use before ever hiring the firm. The kind of thing big firms keep behind a login, given away as the handshake.

How I work

Offline first
Every tool here runs with zero network calls after it loads, by choice. Need something connected instead? That works too.
Fixed price
You know the number before I start. No surprise invoices.
One point of contact
You talk to the person who actually builds it, always.
Ships fast
Tools like the ones shown here ship in one to three weeks, start to finish.

Commissions, plainly

What I take on
Small, focused web tools (a Grouper, a Wildcard, a desk built around your work). Brand systems delivered as working offline documents. Print-ready textbooks, study guides, and training materials. Design audits.
What I don't
Enterprise software, hosted platforms with logins and databases, and open-ended "figure it out as we go" projects. If your project is that shape, I will say so fast and point you somewhere honest.
Timing
I take a small number of commissions at a time, and the school year starts again in September.
The first step
One email describing the thing you wish existed. You get an honest read on fit, then a real number and a real date before I start.

Have something you wish already existed?

Tell me what it is. I will tell you honestly whether it is a good fit. If it is, you will get a real number and a real timeline before we start.
