Location-Based Outdoor Space App Development

(Backend + Test Frontend)

I'm looking for a skilled backend developer to help set up the technical foundation for a minimal, clean location-based app focused on outdoor spaces around Helsinki.

The concept is related to outdoor sports fields, courts, and playground discovery —
but the deeper idea behind the project will be shared fully after the project is accepted.

For now, I need to set up the technical structure that supports the map-based experience.

Key Technical Tasks:
Set up a lightweight backend (Node.js + MongoDB preferred)

Build the following:

Database storage for locations (name, emoji icon, GPS coordinates, photo URL, short description)

One API endpoint:
GET /nearby?lat=...&lon=... → returns locations within 5km

Free hosting setup (Render, Railway, etc.)

Build a simple test webpage:

Dark-themed map (Google Maps or OpenStreetMap)

Use emojis as pins

Tap pin = show small popup (photo + name + description + "Get Directions" button)

Focus on smooth, minimal, Uber-style map feel:

Dark background

Smooth pin loading

Clean simple popup, not heavy or overloaded..
i will send the mock ups of the project after we start to make it happen
