Hi, I'm Alberto Guinda

About the role

I build, single-handedly and from architecture to production, OFITECO’s (VINCI Group) digital-twin platforms for monitoring critical civil infrastructure (dams, tunnels, bridges).

Highlights

• xdata-bim digital twin (BIM + GIS + IoT in the browser): IFC viewer with web-ifc (WASM) and a .frag binary format (load time ~15 s → ~1 s), real-time monitoring over WebSocket and anomaly detection (Z-score, Bollinger, regression, correlation). 37 components, ~840 i18n keys (4 languages), E2E with axe-core (WCAG AA).
• BIM ↔ terrain alignment with CesiumJS + Google 3D Tiles (N-point GPS registration) and 11 official WMS layers (IGN, IGME, CHE/SAIH).
• Edge computer vision across a network of autonomous solar 4G cameras: YOLOv8n (ONNX) + CLIP + SSIM pipeline (~700 ms/frame on CPU).
• BCF 2.1 interoperability (Navisworks/Revit/Solibri) and project PDF reports.
• Pulso — structural health monitoring software (operational modal analysis, 7 steps), Svelte 5 + FastAPI + HDBSCAN, deployed on-premise in production.
• appxdata — cross-platform (Capacitor, Android/iOS) rewrite of the field auscultation app: offline-first, encrypted local database, 4 languages.
• Executive monitoring dashboard — strategic-management panel (Svelte 5 + Leaflet + command palette), with reactive KPIs and cascading filters.
