AI agent · approx. 5 min.
An autonomous quoting workflow with human oversight: Operator One takes a customer request from intake to a ready-to-send quote — CRM research, calculations down to the cent and a finished PDF. A person approves every email before it is sent, and every step remains traceable.
App · approx. 6 min.
My app for reducing food waste: scan a barcode, capture the best-before date with the camera, sort supplies by urgency — and receive a reminder before anything expires. All data stays locally on the device.
Each of these demos also has background and context — on my industry pages.
Operator One and Zerø are my own products — not client work, and I say so deliberately. Before I promise anything, I build it myself, use it myself and stand behind the result. Both projects were built to the same standards I commit to for my clients: self-hosted, GDPR-compliant, fully documented.
Starting point. Writing quotes is the same evening work in almost every business: read the enquiry, look up the customer, calculate the positions, write the cover letter, build the PDF. Each step is simple — together they cost hours in which nobody is selling.
Solution. Operator One takes the enquiry and carries it all the way to a ready-to-send quote: it researches the CRM, calculates to the cent and drafts the cover letter. The decisive point is what it is not allowed to do: nothing leaves the house without human approval. The human reviews and decides — the agent does the legwork.
Today. Operator One runs in production in my own business. Instead of starting every quote from scratch, the finished draft is waiting for review — exactly the division of labour between human and AI that I build for clients: AI & agents.
Starting point. Food ends up in the bin because nobody keeps track of what expires when. That is not a knowledge problem but a reminder problem — which makes it one software can solve.
Solution. Zerø turns the pantry into a sorted list: scan a barcode, capture the best-before date with the camera, order supplies by urgency — and get a reminder before anything expires. All data stays locally on the device.
Today. The app is fully developed and runs as a signed release build in daily use. So far it is distributed directly as an installer file, not through an app store. For me, Zerø is the proof that I cover the whole distance from first concept to release-ready app in-house — the same distance I cover with you: App development.
