Elijah Munn

• Sole full-stack engineer on City Digital Twin (cdt.cat) — a geospatial intelligence platform for urban analysis and spatial decision-making covering 5,000+ census sections across Catalunya (neighborhood → municipality → comarca → province).
• Built end-to-end: backend data pipelines integrating housing, cadastral, economic (INE census), and mobility data; and the frontend letting planners, policymakers, and researchers query, visualize, and compare across scales.
• Produced the product's visual identity — logo, brand, and all media. Delivered for the Torras Family Foundation and Barcelona Global.
• Stack: Next.js · TypeScript · deck.gl · Supabase (Postgres) · Vercel.

• Hired for a single basic website; grew into the engineer "uniquely responsible for the success of the lab's defining projects" — owning frontend, UX, infrastructure, and deployment end-to-end under Prof. Latanya Sweeney (data-privacy pioneer, former FTC CTO).
• fbarchive — complete frontend (React) and design/media for the platform housing Facebook's internal documents for collaborative research and curation.
• JoinU — complete frontend (React Native) and design for the university mobile app driving physical activity through social features.
• MyDataCan — contributed to the user-controlled personal-data platform (data encryption, iOS/Android apps).

• Independent web-design studio — design and build sites and apps for clients and passion projects, bringing craft and visual polish to every interface.

An urban-foresight platform that splits cities into hexagonal cells carrying 100+ metrics across demographics, housing, health, mobility and equity — letting planning teams fork policy scenarios, model agent-based outcomes, and see who benefits before decisions unfold.

An audio-reactive lighting director that separates music into stems, uses an attention model to pick the focus of each frame, and lets Claude compose bar-level light patterns — driving real DMX hardware and a live Three.js visualizer.

A full redesign of the Media Lab's web presence — scraping 600+ live records into a typed content layer and presenting people, projects and events through a 3D-accented, cross-linked editorial system.

Next.js · Three.js · GSAP · Data

An urban-intelligence platform that fuses building, transit, demographic and environmental data across whole regions — rendering millions of buildings with deck.gl and Mapbox, scoring walkability and 15-minute-city access, and modelling policy scenarios in real time.
