ActivityInfo.org

ActivityInfo is a platform for humanitarian data management used by the UN, NGOs and Governments in more than 70 countries. It is a hugely challenging web application with an outsize impact in the world. Some of the work you would do includes: Add new data visualizations to our analysis toolbox, work with our UX designer to build user interfaces that make complex tasks, like dashboard layout, simple for users, increase the performance of our system for large datasets, design and implement multi-level caching for complex analytical queries, improve conflict resolution during synchronization with our offline web client, extend and improve our formula language and its interpreter, develop a pipeline for automated analysis of user data sets, ensure that key tasks in the application are accessible to visually impaired users. Our codebase is written in Java, both frontend and backend. We have high test coverage and use a highly functional flavor of Java to ensure that the compiler can verify as much as possible at build time.
