Geospatial Developer | MapLibre, Three.js 3D Maps, PMTiles, PostGIS

I build MapLibre and Three.js maps that handle real data at scale: interactive globes, 3D cities and terrain, millions of points through vector tiles and PMTiles, fast on mobile. Top Rated, 100% Job Success. I have worked with maps since 2007, first as a cartographer and GIS analyst, then nine years as a developer on a US real estate mapping platform, and since 2019 building real-time 3D web maps for clients. What I build: • MapLibre / Mapbox GL maps and globes: custom styles, clustering, heatmaps, H3 grids, world to street navigation • 3D inside the map: Three.js custom layers, glTF models at true scale, GPU instancing, shaders • Large geospatial data: Tippecanoe and PMTiles on a CDN, PostgreSQL / PostGIS, vector tiles, GraphQL • Map apps for React, and the map layer for React Native teams • Scroll-driven map stories and data visualization (D3, GSAP) Selected work: • Environmental intelligence platform: 2,000,000+ companies on a MapLibre globe, from the world view down to a single company profile • 3D marine platform for reef conservation: terrain, bathymetry and 11M+ hex features, in production for 15+ months • Heritage3D: 30+ 3D landmarks on a live city map (two contracts, both rated 5.0) • Worked with MOBY for their internal tools in collecting and representing ocean data through a web platform (React, TypeScript, Mapbox GL, Node.js, PostgreSQL) How I work: I start from your data and your users, agree the scope in writing, and ship in small working steps you can test. Short written updates every day, few meetings. Based in the EU, with overlap into US mornings. Portfolio and live demos: maptheclouds dot com
