Jan Phillips contributed to the Planning-Inspectorate/applications-service repository by delivering multilingual content localization, expanding file upload capabilities to support DOCX and XLSX formats, and enhancing CSV export with environment-aware data quality links. Jan’s work involved JavaScript and Node.js for front-end and API development, as well as YAML and Terraform for cloud configuration and infrastructure as code. By externalizing Azure Blob Store host configuration and standardizing environment variables, Jan improved deployment flexibility and maintainability. The engineering approach emphasized robust testing, code quality, and configuration management, resulting in features that increased business value, transparency, and adaptability across cloud environments within a short timeframe.
