Pet owners find pet sitters, boarding, vets and trainers near them and book online. Providers manage their calendar and invoices in their own portal.

Starting point

Anyone looking for care for their pet goes through listings and the websites of individual providers. There was no single place to compare, book and pay, and no back office that took work off the providers.

Implementation

Three web apps for pet owners, providers and administration, built with Next.js, plus an API built with NestJS. Data lives in PostgreSQL. Payments run through Stripe, providers issue QR-bills. Maps with Leaflet and MapLibre show offers nearby. The web apps run on Vercel in Frankfurt.

Result

Live at app.animeets.ch. Pet owners search by town or postcode, providers work in their own portal.

A family-run dog care business in Gossau ZH offering boarding, day care and dog walking. The website brings in enquiries in six languages, while occupancy and monthly invoices run in the background.

Starting point

A small business needed a website that is found in the region and answers questions about prices and the process up front. Occupancy and invoices should no longer be put together by hand in spreadsheets.

Implementation

A fast website built with Astro and Tailwind CSS, in six languages with translated URLs and dedicated pages for the towns of the Zürcher Oberland. It adds guides, a price calculator with a PDF quote and a contact form that confirms by email. A protected internal tool keeps occupancy and the daily plan and creates monthly invoices with a QR payment part. Data in PostgreSQL, hosted on Vercel.

Result

Live at pfoten-pfad.ch. Enquiries arrive through the form, quotes and monthly invoices are created in the business's own tool.

TEXFY collects open tenders from simap.ch and other sources. Businesses first see what matches their services and cantons, with a reason and the deadline.

Starting point

New tenders appear on simap.ch all the time. Small businesses have no time to read them all and miss suitable contracts or deadlines.

Implementation

Web app built with Next.js and TypeScript, data in PostgreSQL with Drizzle. Regular imports fetch tenders from simap.ch, TED and cantonal sources. A grade from A to E explains why a contract fits. Google Gemini summarises tender documents with verbatim quotes as evidence. Sign-in via email link, Pro subscription through Stripe, four languages, hosted on Railway.

Result

Live at texfy.ch, with a free tier and a Pro subscription. Businesses get saved searches, deadline reminders and a board for their bids as a team.

Collectors search for or photograph a card and see its estimated value with a range and data quality. A calculator shows whether sending it to a grading service pays off.

Starting point

Trading card prices swing widely, and single sales say little. Collectors need an estimate that openly shows how reliable it is.

Implementation

Web app built with Next.js, React and TypeScript. Card data comes only from official APIs such as Scryfall, TCGdex and YGOPRODeck, exchange rates for CHF, EUR, USD and GBP from the ECB. PostgreSQL with Drizzle, background jobs with pg-boss, text recognition with tesseract.js. The web interface runs on Vercel, the background service on Railway.

Result

Running as a closed beta at holofoilx.artiomining.ch, free and by invitation. If the data for a card is not sufficient, HoloFoilX deliberately shows no value.
