Gov Data Pulling App

I am seeking an experienced mobile app developer to build an application that extracts and presents key government data sets to users in the United Kingdom. The app would periodically retrieve open data from credible UK sources like data.gov.uk through public APIs and display metrics and statistics in an easy-to-read format. Examples include health metrics, economic indicators, environmental benchmarks and educational outcomes. Users should be able to filter the data by location, demographic and time period.

The frontend would have a clean, minimalistic interface optimized for both iPhone and Android. Data sets must be refreshed regularly through automated weekly/monthly calls to data sources. Backend services are needed to store cached results, handle API tokens and authenticate data sources. Developer is expected to research authoritative UK agencies, evaluate available open data resources and curate the most relevant and frequently updated metrics for the app. Security, privacy and legal compliance with relevant open data licenses and terms of use is a must.

Unit testing, continuous integration and monitoring are important to ensure high performance and uptime. The app should work offline by storing common queries locally when internet is unavailable. Documentation for app architecture, data sources and expansion roadmap must be provided. Interested developers please review requirements and respond with examples of similar work experience and estimated timeline to complete this project within agreed budget.
