Multi-tenant digital menu builder with AI menu import - design a menu, publish it as a link or QR code

A restaurant designs its menu in a dashboard - categories, dishes, prices, allergens, translations - and diners open it from a QR code on the table. Tenant isolation is enforced in Postgres, not in the client, and there is a shared demo account so nobody has to sign up to look around. Owners can also import an existing menu from a PDF or a photo: Gemini drafts it, the owner checks it, and an eval measures how often the draft is right. I first worked on a menu builder like this as an intern at Spark Solutions in 2022-2023; that product is theirs, and this is a 2026 rebuild written from scratch.

Tests

Industrial condition-monitoring dashboard - a public rebuild of a factory-floor product

The operator's window into a plant: which machines need attention and when. The production version read live telemetry from InfluxDB and published operator commands back over MQTT. This is the same interface rebuilt with deterministic simulated data, four runtime dependencies and no UI framework.

Runtime dependencies

4 - vue, pinia, vue-router, vue-i18n

UI primitives

14, hand-built, no component or chart library

Tests

34 passing, including the accessibility claims

A wellness clinic's site, booking and CMS - shipped without a backend, at €0 a month

Twenty-nine routes covering a service catalogue, online booking, a self-editable Markdown blog, client accounts and campaign landing pages - with Firestore security rules doing the work a server usually does. I also ran the clinic's paid social, so product decisions were made with acquisition cost in view.

Routes

29 - 20 public, 9 admin

Backend

none · 9 Firestore collections · rules carry authorization

Search

8 routes prerendered · per-page JSON-LD · sitemap from the same data module

Assessment and recruitment platform for a university department - five quiz engines, one data model

Visitors at admissions fairs take a quiz on their phone in under two minutes and get a designed result they can keep. Staff author the quizzes, swap the landing copy per event, and export anonymised responses for actual research. The hard constraints were legal, not visual: the audience includes minors.

Quiz engines

5 - assessment, personality, multiple intelligences, crossword, questionnaire

Data model

20 routes · 9 collections · 3 roles

Minors' data

responses stored unlinked from contact details, enforced in rules

Trilingual memorial and content platform, with an admin panel elderly volunteers actually use

The association commemorates Moldovan police officers who died in the 1992 Dniester conflict. They had decades of photographs, press and footage, and no way to publish any of it. The readers are the public; the editors are veterans who have never used a CMS - every authoring flow had to survive that.
