Civic open data platform for Meran
A free, multilingual information site for Meran/Merano that combines open data on public transport (live departures, delays, timetables), parking, EV charging, pharmacies, doctors on duty, waste collection and municipal news, with a map. No tracking, no accounts. A small Go collector reads public sources such as the South Tyrol Open Data Hub, the provincial transport and health services, and OpenStreetMap. Live bus positions and delays update in short intervals, and the timetables refresh daily. The results are published as JSON files that the static site reads, so there is no application server to run.

Multi-tenant business-operations SaaS for freelancers and small businesses
Customers, projects, time tracking, task boards, appointments with a calendar feed, invoicing, expenses, a simple asset register, and financial dashboards with budgets and revenue plans, all in one app. It has per-tenant data isolation. For Italian companies it imports Fattura Elettronica files (FatturaPA XML and signed .p7m) and turns them into invoices. Invoicing otherwise stays country-neutral, so it works for companies outside Italy too. Data is encrypted at the application level. The UI and user manual are in four languages.

COVID-19 data portal
Pandemic data pipeline and static website generator
Python fetchers collected COVID-19 data from more than a dozen public sources, including Johns Hopkins CSSE, Google’s open COVID-19 dataset and national health agencies. Processors normalized it and stored it in PostgreSQL. A generator then built a static website with charts and map videos showing how the pandemic spread over time, covering countries worldwide and, where data was available, regions and districts. The pipeline provided data for peer-reviewed research published in the International Journal of Cancer (2022). Updates stopped in June 2021; the site remains online as an archive.
