Over a two-month period, contributed to the DiamondLightSource/workflows repository by building real-time observability features and improving developer experience. Developed GraphQL subscription support for workflow events, integrating with the Kubernetes and Argo Workflows APIs and exposing live updates through the Axum web framework using Rust. This enabled operators and developers to monitor workflow state changes in real time, supporting faster incident response and debugging. Additionally, delivered a local development environment for the Sessionspaces backend, providing a Docker-based setup with a mock ISPYB database and comprehensive documentation. These efforts streamlined onboarding, standardized development environments, and accelerated feature validation for the team.
September 2025: Delivered a local development environment for the Sessionspaces backend in DiamondLightSource/workflows, enabling developers to spin up a realistic, containerized backend locally with a mock ISPYB database. The setup includes a Dockerfile, docker-compose.yml, and a comprehensive README with setup and usage instructions. No major bugs were fixed this month; existing issues remain tracked for future sprints. This work reduces onboarding time, standardizes dev/test environments, and accelerates feature validation, representing a meaningful step toward faster delivery and improved collaboration.

June 2025: Focused on delivering real-time observability for workflows via Graph-Proxy subscriptions. Implemented GraphQL real-time subscriptions for workflow events, integrated with Kubernetes API and Argo Workflows API, and wired into the Axum web framework to enable live monitoring and dashboards. This provides immediate visibility into workflow state changes, accelerates incident response and debugging, and lays the foundation for real-time dashboards and alerts. Deliverable center: Graph-Proxy Real-time Workflow Subscriptions in DiamondLightSource/workflows.
