Python/PostgreSQL with Map Server API integration
1002 USD 
I am looking for an experienced developer to support and extend the functionality of an existing project. The main focus is on the backend using Python and PostgreSQL, as well as integration with the API of a mapping server.
Main responsibilities:
Maintaining existing code
Improving performance
Extending backend functionality and API integration
Desired skills and experience:
High competence in Python and PostgreSQL
Experience working with mapping server APIs
Knowledge of Vue.js for potential frontend tasks
Experience in code optimization and feature expansion
Project description:
We are creating a tool for geospatial analysis and are looking for a backend developer with experience working with Python, PostgreSQL/PostGIS, and mapping servers (GeoServer, MapServer, QGIS Server, etc.). Experience with Vue.js for frontend integration will be an advantage.
The main goal is to update the backend API that connects the PostgreSQL/PostGIS database with the frontend mapping application. The frontend needs to be developed from scratch. The API should allow dynamic loading/unloading of layers and filtering geometries by attributes. The client should receive geometries with their attributes from the database in response.
Key tasks:
Analyze and update the API in Python (FastAPI or Flask) for accessing geospatial data
Research and update the connection of the API to the PostgreSQL + PostGIS database
Create endpoints for:
List of all available layers
Enabling/disabling specific layers on the frontend
Filtering objects by attributes with GeoJSON return
Integration with Map Server (GeoServer, QGIS Server, or similar) for serving tiles/vectors
(Optional) Create a Vue.js component or demo application with:
Layer management
Object filtering on the map
Main functions:
CRUD operations for mapping layers
Layer metadata (name, description, schema)
Filtering by attributes (type, category, status, etc.)
Output in GeoJSON format
Simple token-based security
Filter switcher: Active / Inactive / All
Preferred skills:
Integration with Vue.js frontend
Configuration via Docker
Performance optimization for datasets with over 500,000 geometries
Caching (Redis or similar)
Expected results:
Python API source code with comments
PostgreSQL/PostGIS database schema (with test data)
REST API documentation (e.g., Swagger/OpenAPI)
(Optional) Vue.js frontend (demo with layer switching and filtering)
README with setup instructions
Required skills:
Python (FastAPI or Flask)
PostgreSQL / PostGIS
GeoJSON, RESTful API
Experience with Map Server (GeoServer, QGIS Server, etc.)
Vue.js (preferably for frontend)
How to apply:
Please send:
Information about relevant experience (especially with PostGIS or geospatial projects)
Portfolio or GitHub link (if available)
Your preferred tech stack (FastAPI / Flask / others)
Required skills:
Python
Django
Geospatial data
PostgreSQL
Vue.js framework

Hello!
We have experience in developing geospatial solutions using PostgreSQL + PostGIS, FastAPI, GeoJSON, integration with GeoServer, as well as creating APIs for uploading/filtering geometries and transmitting them to the frontend.
We have worked with large datasets (500k+ objects), caching via Redis, and basic security (JWT tokens).
Our team of developers can complete the project quickly, reliably, and cleanly, with documentation, tests, and the possibility of future expansion.
Send us a private message — we will respond quickly, discuss details, and propose the optimal execution plan.
