Mobile and app development, built for the ward
Works offlineand keeps the trail
Signal comes and goes on a ward. The app collects anyway, then syncs when the connection returns. So the queue on the device is part of the study record. Two people edit the same visit offline, and the app has to hold both versions and record which arrived first. Whether it counts as a medical device is worth settling before anybody draws a screen.

What actually slows medtech and clinical research teams
The record keeps the value and loses the history
A record that updates in place keeps the current value and loses the one before it. Good Clinical Practice wants the old value, who changed it, when, and why. Adding that after the study opens means going back through backups to work out what the field used to say.
Consent is easy to take and hard to withdraw
The form captures it once and stores a yes. A withdrawal has to reach the analysis extract, the copy the statistician pulled for the interim look, and the partner who already has a dashboard. Capturing consent is a field in a database, and acting on its removal is a job that touches everything downstream.
Every site connects in a different way
One trust offers an HL7 v2 feed, another a FHIR endpoint that only answers from inside the network, and a third sends a spreadsheet somebody types into REDCap by hand. Each new site restarts the DSPT and DTAC conversation from the top, with a different information governance lead.
Pseudonymised still points back at a person
Strip the DICOM header and the patient's name can still be burnt into the pixels. The free-text box a clinician typed into carries more than every tick box on the form. The key linking a study ID to a patient has to live somewhere, and where it lives is the question.
mobile and app development
Most of what gets asked for as an app is a website that works properly on a phone. You will hear that first. Where the platform genuinely needs a native shell, for push, camera or offline work, it gets one. The web build and the app share one TypeScript core, so the domain model and the API layer are written once, by one person. A rule changes in one place, and both builds inherit it.
- A written answer on whether to build
- Before anything gets built you get the honest read on whether an app is the right answer, with the mobile web version priced next to it. If the answer is no, the document says no.
- One codebase behind the web and the apps
- The website, the iOS app and the Android app are built from the same code and the same API layer, so a change to the rules is written once. No second copy quietly disagrees with the first.
- Getting through App Store and Play review
- Signing keys, privacy forms, the age rating and screenshots at every size go in under your own store accounts. If a build gets knocked back, getting it through is my job and not yours.

Scope
One call, then a written spec. What it does, what it deliberately does not do, and what milestone one is. You sign that off before I write a line.
- 02Early
First deploy
A narrow slice that actually works, running where it belongs. A URL you can open, a build on your phone, a job on your own servers. Real data, real hosting, no placeholder screens.
- 03Ongoing
Build in the open
Deploys land as the thing fills in, not in one drop at the end. You watch it happen. And you get to change your mind while changing it is still cheap.

Yours to run
The product runs in your accounts, with the domain, hosting and documentation under your control. Source-code transfer is quoted separately; we agree what is included during scoping.

I got my hands on a computer at 6 and never really stopped.
Now it is decentralised finance, tokenising real-world assets and topological deep learning, then building whatever those turn into. Continuum came out of that. So did Delta Xi (δξ, an infinitesimal change in a random variable).
Bossa nova and MPB were always on at home, so I sang before I played anything. Guitar and piano came later, then jazz.

Need the audience too?
I can build the thing. Getting people to notice it is a separate job, and not mine. For that I work with Nytforge, who film, edit and put the work in front of a local audience. They are strongest with automotive and local businesses.
