From late 2021 I developed and ran a Hungarian real estate listing platform that I built from scratch in PHP. Since 2025 I have been building my own products: an IT job aggregator with 70,000+ listings, EU-hosted map infrastructure and live data maps.
I designed, built and run each of these myself, on EU infrastructure.
Vector and raster map tiles for Leaflet and MapLibre, typo-tolerant geocoding down to house numbers, routing and a nearby-places API. Served from my own EU servers, with no visitor tracking.
