Built and shipped,
not proposed.
Not a portfolio of client logos. This is the range of things I actually make — a page for one wedding, a tool nobody else would ever need, and the infrastructure that keeps the rest of it standing up.
HorseDex
A health journal for a horse. You write down what you did and what you saw; it keeps the record and shows it back to you over time, for one horse or for several. Built for one person to begin with, then rebuilt so anyone could use it, and released free on the App Store.
- No account to create and no server of mine — the records stay on your devices and in your own iCloud
- Free on the App Store, because I chose to release it
- Out since 26 August 2026, for iPhone, iPad and Mac
everafter
A wedding page that becomes a remembering page. Guests view the day, add their own photos and video, and leave a note. After the date it flips to remembering mode and counts the anniversaries.
- Runs on the couple’s own server, photos as ordinary files on their disk
- A reception wall for the projector, and a print-ready photo book
- Every original downloadable as a zip — getting the data out is a link, not a support ticket
TKVoiP
A telephony and call-handling interface built around one specific way of working, rather than bending that way of working around someone else’s software.
- Live status, built for glancing at rather than reading
- Talks directly to the telephony API
- Small, fast and single-purpose
Private infrastructure
The things nobody sees. Self-hosted services, backup pipelines that verify their own restores, energy and solar monitoring pulling live data off hardware and tariffs.
- Built for myself first, which is why I trust the patterns I sell
- Containers, scheduled jobs, monitoring and the recovery drills
- No client, no showreel — just the reason the rest of this works
What is not here
Work aimed at growing somebody else’s business — a new website, brand design, search and AI visibility, a review of the tech behind it — sits with Kalkman Digital, along with the smaller job-and-customer tools built for its own website clients. Looking after something once it is running — support for a business, training, the public’s own machines — is Kalkman Tech. That is a deliberate line, not an oversight.
Some builds are private and stay that way. A memorial for a family, a system running inside one business, a tool made for one person — none of those are mine to put on a page with a link on it.
Something you want built?
Commissions start with a free conversation, then a paid piece of scoping work, so the price at the end is a real one.
