I Built an AI Content Pipeline That Refuses to Fake Data

For about two months I shipped things and wrote about none of them. Orbit got a payments engine, Pulso became a native iOS app, the website got a real intake form. Writing it up was always the last item on the list, which is another way of saying it was never the item. So I built Pluma, an AI content…

What I learned building JARVIS’s daily voice briefing

What I learned building JARVIS's daily voice briefing JARVIS is my personal AI chief-of-staff -- a voice-first HUD that's supposed to tell me what actually matters about my day without me having to go looking for it. Most of this stretch was about making that briefing trustworthy rather than just present. The email triage loop was re-judging the same roughly…

Pulso iOS Stopped Being Read-Only

Until 30 July, Pulso on the phone could show you everything and change nothing. It read the live API, rendered the collection, and that was the whole contract. On the evening of the 30th that changed: the app writes now. The add-watch flow went in behind the FAB, search then enrich then save, and I gated it deliberately. It spends…

Building Vela’s widget system: 13 designs, nine that made it

Widgets were the one part of Vela iOS I designed before I built, on purpose. I laid out 13 widget concepts first, including a bills-runway view and a payday countdown, as mockups I could react to before any Swift got written, and nine of those thirteen made it into the app as real, native widgets: safe-to-spend (with a lock-screen version),…

Pluma’s Build Log: the post writing about itself

This entry exists because of a question I asked out loud: does every update across every app really need its own blog post? The honest answer turned out to be no, not on the main blog, that stays reserved for one real cross-project story a week, but yes, somewhere, because yeison.co.uk already had a Build Log section built for exactly…

Teaching Pluma to find its own pictures

A post about something visual is weaker without the visual, and until this week getting one into Pluma meant me manually screenshotting and uploading after the fact. Now any Claude Code session, on any of my projects, can render a real image straight from the actual design artifact or a genuine Simulator screenshot, upload it, and stage it, without writing…

The same SwiftUI bug, five different disguises

This week's bug list for Vela iOS reads like the same mistake wearing five different outfits. SwiftUI lets you stack two .sheet modifiers on one view and it will not warn you, it just silently honours the last one and ignores the first. Settings had exactly that: two sheets, so tapping "Start fresh" did precisely nothing, no error, no crash,…

Vela iOS: from empty repo to full parity in under 24 hours

On 30 July I had Claude Code create the Jason9347/vela-ios repository at 6am UK time. By 6:43am there was a read-only core: login, Overview, Accounts, Transactions, Plan, Fixed costs, Income, a Face ID mask over the numbers, and the app's appearance settings. Nine minutes later the remaining read-only screens landed too. That's not a typo, less than an hour from…
