Mara Karagianni
Worked on the liqd/a4-meinberlin repository, delivering features and stability improvements across backend and frontend systems. Built personalized search and location-based discovery with Django and Django REST Framework, implementing robust models, serializers, and API endpoints for Kiezradar. Enhanced geospatial workflows by integrating GIS data into admin dashboards and enabling radius-based project filtering. Addressed reliability through targeted bug fixes, including template context handling and serializer dependency updates, while improving test coverage and documentation. Leveraged Python, SQL, and JavaScript to support scalable data management, CI/CD cache hygiene, and UI/UX modernization, resulting in more accurate search, improved data integrity, and streamlined deployments.

Apr 1, 2025April 2025 monthly highlights for liqd/a4-meinberlin focused on geospatial admin enhancements, robust media handling, and CI/CD reliability to improve data integrity and deployment hygiene. Delivered GISModelAdmin-backed admin interfaces for Projects and Plans with sensible default map views to render geospatial data in Django admin dashboards. Introduced a Django management command to clear caches for projects and plans, integrating cache hygiene into the CI/CD pipeline for clean builds. Implemented robust image thumbnailing and plan serialization fixes with cross-serializer exception handling to reduce runtime errors when handling corrupted images. Updated dependencies to mb-v2504.2 to align tooling and ensure stability. These changes reduce manual work, improve data integrity, and accelerate safe deployments while enhancing geospatial workflows.
