Addris

Addris started from a simple frustration: when you look at a property, the listing tells you about the building, but almost nothing about the place. What's actually around it? What's being built nearby? Is it on a flood plain? How far to a charger, a bus stop, a school? That context is the thing that actually changes a decision, and it's scattered across a dozen government datasets that no normal person is going to stitch together.

What it does

Addris pulls those sources into one map and one picture of an area. Behind it sits a fair bit of Ireland: over 635,000 properties from the Price Register, ~155,000 commercial properties, planning applications, transport stops from the national GTFS feed, EV chargers, local services, and flood-risk zones from the OPW. You point it at an address and it tells you the story of the area around it — sold prices, planning activity, and the trajectory of the neighbourhood — not just the four walls.

The hard part was the data

The product is geospatial, but the real work was the data pipeline. Everything is keyed on location, which in Ireland means Eircodes — and Eircodes are gloriously non-geographic, so you can't infer a neighbour from a code. Geocoding all of it ran through a paid API and a self-hosted Photon instance for the bulk work, with a cache so I wasn't paying to look up the same address twice. It runs on AWS — PostGIS on RDS for the spatial queries, Redis for the hot paths, a fleet of Lambdas for ingestion, with MapTiler doing the tiles. The Eircode geocoding layer alone represents real money and time, which is exactly why it's the one dataset I made sure was backed up before anything else.

An honest status update

Here's the part most write-ups skip. Addris is paused. While doing customer discovery I came to the conclusion that the stronger opportunity is B2B — feeding this area intelligence into partners who already have the customers — rather than another consumer property portal. So I stepped the consumer product back: the infrastructure is torn down to near-zero cost, every dataset is preserved in cold storage, and there's a one-command playbook to bring it all back online in an afternoon.

That's not failure, it's a deliberate pause to point the work at the right buyer. The maps, the pipeline and the data are all real and all kept. You can see the project at addris.ie, currently on hiatus while I chase the B2B angle.
