Title: Geospatial Backend Developer Needed for Google Earth Engine Integration Project Description: We have built an interactive web application prototype that serves as a powerful dashboard for geospatial analysis. The frontend is built with and React, and it currently simulates the display of various satellite imagery layers (e.g., NDVI, Landsat, Sentinel-2) using mock data and static tile URLs. The goal of this project is to replace these mock integrations with a live, dynamic backend service. We need an experienced developer to build the core data pipeline that will connect our application to real satellite imagery APIs, with the initial focus on Google Earth Engine, and later Planet and Blacksky imagery. This is the first and most critical phase of moving our application from a proto...

Senior Geospatial Engineer (Python + PostGIS) Overview We’re building a high-performance mapping platform that allows users to draw areas on a map and instantly return accurate address counts. We hold a dataset of 30M+ UK addresses (lat/lng) and need to ensure queries are fast, scalable and highly accurate. What we need We’re looking for a senior geospatial engineer to work alongside our developer and help refine the architecture and implementation. Scope of work Optimise spatial queries across large datasets (30M+ points) Ensure near-instant response times Implement best practices for spatial indexing (PostGIS / GiST) Support handling of: Polygons Radius queries Buffers (routes) Boundaries GIS uploads (GeoJSON / shapefiles) Ensure consistent accuracy across all query type...

I run an academic journal on the latest OJS release and need a reliable hand to keep the platform healthy and secure over the long term. My immediate focus is routine maintenance rather than initial setup or theming. The work centres on: • Regular backups – full files + database, stored off-site and easily restorable. • Security updates – prompt core and plugin patching so the installation stays hardened. • Plugin management – monitoring compatibility, applying updates, and de-activating anything that risks stability. I already handle day-to-day editorial tasks; I simply want to know the technical side is covered. Familiarity with OJS upgrade paths, PHP, MySQL, and cPanel-style hosting will be essential. Please outline the cadence you recommend ...
