Freelance R shiny application developer (freelance)
Job Description
Background
Equity is at the heart of the 2030 Agenda for Sustainable Development. In pledging to achieve the Sustainable Development Goals, countries have committed to leave no one behind. Monitoring health inequalities is critical to understand who is being left behind as it can identify differences in health between different population subgroups. This is essential for the development of equity-oriented interventions, especially those on the path to universal health coverage.
To build and strengthen the capacity of countries to monitor health inequalities, WHO has developed the Health Equity Assessment Toolkit, a software application that enables users to explore and compare inequalities in countries using disaggregated data and summary measures of inequality that are visualized in an interactive and customizable way. The software is available in 2 editions:
- HEAT, the built-in database edition, which contains data from the WHO Health Equity Monitor database,
- HEAT Plus, the upload database edition, which does not contain any data, but allows users to upload and work with their own datasets.
HEAT is available as an online version and as a standalone version for use offline. HEAT Plus is currently only available as a standalone version. (http://www.who.int/gho/health_equity/assessment_toolkit/en/)
Both HEAT and HEAT Plus have been developed using R and a number of different R packages, including shiny. The software is free and open source and has been released under the GNU GPL v 2.0 license.
