About this gig

I'll build an interactive map for your web application using 

Mapbox or Leaflet with custom layers, filters, clustering, 

and smooth performance even on large datasets.


I specialize in geospatial frontend development and have built 

data-heavy map platforms for government infrastructure: seismic 

risk maps, urban accessibility tools, and real-time monitoring 

dashboards.


What I can build for you:

- Interactive maps with custom markers, popups, and layers

- Data-driven maps with filters and search

- Maps with clustering for large point datasets

- Heatmaps and choropleth visualizations

- Click-to-detail panels with charts and stats

- Full integration with your backend or REST API


Tech stack: React, Next.js, TypeScript, Mapbox GL JS, 

Leaflet, GeoJSON, Turf.js, Recharts.


If you have a map project basic or complex message me 

first and I'll tell you honestly if I can help and how long 

it will take.
