GIS & Mapping Applications
I build interactive mapping and geospatial applications — heatmaps, geocoding, location-based search, and field data collection — that turn raw coordinates into something teams and the public can actually use.
The problem I solve
Geospatial data is powerful but hard to present. Most teams have the data and no good way to explore it, filter it, or collect more of it from the field.
How I work
- 01Choose the right mapping stack (Leaflet or MapBox) for your data and budget.
- 02Build interactive layers, heatmaps, and filters that make the data explorable.
- 03Add geocoding and location search where users need it.
- 04Support field data collection with offline sync if needed.
What you get
- Interactive map application
- Heatmaps, layers, and filtering
- Geocoding and location search
- Optional field-collection mobile app

Frequently asked questions
Have you built GIS apps in production?
Yes — I built AREC GIS, a platform adopted by the Philippine Department of Energy to track renewable-energy systems nationwide. See the case study below.
Can users collect data in the field?
Yes — I can pair the web app with a mobile app that supports offline data collection and syncs when back online.
