Orbital Mechanics Simulator

Real-time 3D satellite propagation on a photorealistic globe. Add any object by NORAD ID and watch live SGP4 physics: ground-track trails, day/night terminator shading, a time scrubber (T+hh:mm:ss), orbital-elements readout, conjunction detection (CDM), and a true-scale Sun and Moon.

ES256 JWKS authentication written from scratch · per-user satellite isolation · TLE fetched client-side · satellites rendered at true orbital altitude with SGP4 propagation updated in real time.

Geopolitical Intelligence Map

Globe-projection world map with 20 economic and social heatmaps (GDP/cap, Gini, HDI, CO₂, life expectancy and more) across 217 countries with province-level data for all territories, US county resolution, and on-demand AI risk briefings generated by Claude Haiku — cached to Postgres so each briefing is only computed once.

Historical Atlas

Ask any question about European political and military history 1900–2000 and watch the map respond: borders redraw by era, key moments surface as a timeline, and countries highlight as the narrative streams in. Click any country for an AI-generated fact card with era-accurate names, political context, and citations. Query history, PNG export, and full mobile support.

RAG pipeline over historical documents · pgvector semantic retrieval · Pydantic AI structured output for both timeline and country facts · Mapbox GL JS feature-state hover highlighting · SSE streaming with monospace typewriter rendering

Admissible Regions for Untracked LEO Debris

MSc thesis at Airbus Defence & Space, Friedrichshafen. Developed admissible-region methods to generate initial orbit catalogues for untracked LEO objects detected by ground-based optical telescopes · bridging astrodynamics, estimation theory, and sensor geometry to address a live problem in space situational awareness.

Supervised jointly by TU Delft and Airbus D&S · Published in TU Delft repository · MSc GPA 8.0 / 10

Background
46 countries. Grew up across NL · DE · IT · ES. Presented at IAC Milan. Built things in four languages.
Outside work
Training for an Ironman. Judo, tennis, gym. Dutch Red Cross volunteer. Guitar.
How I work
Direct. Ship something real before you architect the perfect thing. I care more about what works than what sounds good. The goal is space · everything else is how I get there.
