PROFILE

Simon Dunn

Over four months, contributed to DEFRA/fcp-fd-data and DEFRA/fcp-fd-comms by building foundational backend features and improving code quality. Developed a PostgreSQL database infrastructure using Docker and Sequelize, implemented a GraphQL API layer with Apollo Server, and enhanced observability through improved logging and environment-based configuration. Introduced file metadata handling and standardized code review processes with documentation updates and a pull request template. Refactored code for readability and maintainability, addressing technical debt and resource management, including connection leak prevention. Worked primarily with JavaScript, YAML, and Dockerfile, focusing on robust API development, database integration, and scalable, maintainable backend architecture across both repositories.

December 2024: Delivered a GraphQL API Layer with Apollo Server and GraphiQL Explorer for DEFRA/fcp-fd-data, enabling efficient data access and developer tooling while tightening security in production. Implemented environment-based introspection so GraphQL explorer is available in development/testing but disabled in production. Cleaned production logs by removing an unnecessary console log from the /healthy health check, reducing noise and improving observability. These changes collectively improve data query performance, developer productivity, and operational quality.
