PWA (progressive web app)

A website with a manifest and a service worker, so it can be installed, work offline and be packaged for app stores.

A web app manifest gives the site a name, icons and a start page; a service worker answers requests when there is no network. With both, browsers offer to install it, and Android can ship it to Google Play as a Trusted Web Activity. For the App Store, a wrapper such as Capacitor is the usual path.

“a true bias for action” client CTO, public LinkedIn recommendation

Confidential by default. NDA is standard. I never show your project, name or screenshots without written consent, which is why this site names no clients without permission.
Your code, your accounts. Code and data stay in your repository and accounts. AI tools run with training on your data turned off, and secrets never reach a model.
A handover you can use. Every project ends with the same checklist: a README that gets it running, one architecture diagram, written decisions, CI, a runbook and a recorded walkthrough. It is done when someone outside the project can run it from the docs.
Boring technology where it counts. I pick a stack you can hire for. Anything experimental needs your yes and an exit plan.
Approach matched to your risk appetite. Prototype, product or regulated: the level decides how much autonomy the agents get and how much review and validation each change needs.
Everything checkable. Every number on my pages links to its source. My tools are free, and the idea validator skill is open source (MIT).
