Dhany Yudi Prasetyo
I build routing engines, WebGIS applications, and spatial data systems for mobility and infrastructure.
GIS Platform
A GIS platform that keeps an organisation's geospatial data in one catalog and turns it into 2D maps, 3D scenes, analyses, dashboards and story maps. Every layer is also served as WMS, WFS and OGC API, so QGIS and ArcGIS read what the browser shows.
Enterprise GIS & LiDAR
Enterprise asset management digital twin for PT Hutama Karya (Persero). Integrating ArcGIS Enterprise with UAV LiDAR terrain models across a 131.69 km toll corridor.
Spatial Analysis
A spatial validation workflow for comparing geofence files and finding overlaps. Validates polygon integrity and normalizes 2D elevation.
Validation result: the uploaded Zone A had 4 issues (a self-intersection at 103.83536, 1.27753, a duplicate vertex, clockwise winding and Z values of 412 m). After auto-fix it is a valid RFC 7946 Polygon with 8 vertices in EPSG:4326, and it overlaps delivery Zone B by 0.049 km².
3D GIS & BIM
A 3D GIS digital twin of Urban Heights Residence that brings BIM into a geographic scene. Every unit is a queryable feature with its floor, area, price and ownership share.
Spatial APIs
Indonesian administrative regions API for location forms and spatial workflows. High-performance boundary hierarchy and geospatial query endpoints.
Administrative boundaries: Wilayah-ID API · Dukcapil 2024
Six provinces and 119 regencies and cities on Java
Disaster Response
Disaster response platform across web and mobile. An evacuation guide and incident reporting system for communities around Mount Merapi.

Developed a modern RESTful API wrapper for the Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG) open data. This project seamlessly converts legacy XML weather and earthquake data into developer-friendly JSON format. It features a robust Model Context Protocol (MCP) integration, allowing AI agents to natively query real-time Indonesian weather forecasts and seismic activity…
Indonesian Routing Optimization Game. Player vs Valhalla & AI routing solver featuring authentic local constraints: odd-even plates, tidal floods, prayer breaks, and the Nusantara corridor. Built with Next.js 16, Go, and Valhalla. Top 100 #JuaraVibeCoding 2026.
Open .osm.pbf road extracts right in the browser. Parsed in Web Workers, color-coded by road class, with routing, tag editing, GeoParquet export and AI queries in English or Indonesian.
A real-time alerting service designed to monitor the BMKG API and dispatch instant notifications for significant weather events and earthquakes across Indonesia. The system continuously polls the data feeds and pushes formatted alerts to external messaging platforms via webhooks whenever predefined risk thresholds are met. Fully containerized with Docker for easy self-hosted deployment.
Teaching experience with professional partners, supported by recommendations from colleagues and mentors who have worked with me directly.
