The Experience

Built and maintained backend services and web features that supported internal operations and public facing platforms across multiple programmes. I implemented Spring Boot services and REST endpoints and connected them to React and TypeScript interfaces, with a focus on reliability and straightforward maintainability. Part of the work involved improving older workflows and reducing recurring runtime issues by moving away from ad hoc PHP based flows toward a more structured Java service layer. I also supported day to day content and operations with repeatable tooling and scripts, helping reduce manual publishing effort and improving consistency for recurring updates and campaigns.
