Over five months, Fredrik Mellum developed and maintained the equinor/acidwatch repository, focusing on backend API foundations, authentication, and deployment reliability. He built initial API scaffolding using FastAPI and TypeScript, implemented secure authentication flows, and integrated distributed tracing with OpenTelemetry and Azure Monitor to enhance observability. Fredrik improved CI/CD pipelines with GitHub Actions, enforced code formatting standards, and streamlined Docker deployment to ensure consistent application startup. He addressed configuration clarity and reduced maintenance overhead by removing unused endpoints and cleaning environment variables. His work demonstrated depth in backend development, API security, and DevOps, resulting in a stable, maintainable codebase.

Month: 2025-10 — Focused on API cleanup and codebase hygiene for equinor/acidwatch. No new user-facing features; the work centered on removing an unused endpoint to reduce maintenance burden and confusion, improving API clarity and long-term stability.

December 2024: Focused on stabilizing backend deployment in Docker for the equinor/acidwatch project. Implemented a critical Dockerfile correction to ensure the container boots the correct application (acidwatch_api.app) rather than co2specdemo_backend.app, improving startup reliability across environments and smoothing CI/CD pipelines.

November 2024 monthly performance summary for equinor/acidwatch. Delivered foundational backend API scaffolding with authentication and routing for simulation models (CO2SPEC, ARCS) and a dummy model for testing. Implemented CI/CD and repo hygiene improvements to raise reliability and maintainability: enforced Prettier formatting, added automated formatting checks in CI, fixed npm caching in CI, adjusted deployment port configurations, and removed unused artifacts. These workstreams reduce deployment risk, accelerate feature delivery, and set a stable baseline for upcoming simulation features.
