Céline Pelletier contributed to the radiant-network/radiant-portal repository by building and refining backend APIs and data models that support complex biomedical workflows. Over eight months, she delivered features such as unified search, variant data enrichment, and user preferences management, focusing on scalable data handling and workflow clarity. Her technical approach emphasized robust API design, database migrations, and integration testing, using Go, TypeScript, and PostgreSQL. She applied the repository pattern and Docker-based local environments to improve maintainability and onboarding. The work demonstrated depth in backend development, with careful attention to data quality, test coverage, and seamless integration between backend and frontend.

September 2025 deliverables focused on API simplification and reliability for radiant-portal. Implemented a major Saved Filters API revamp by consolidating two endpoints into a single surface, removing user_id from the path, and introducing a DELETE-by-id endpoint. Added integration tests and updated OpenAPI documentation to reflect the new API surface. Result is a cleaner, more maintainable API that reduces confusion for consumers and lowers future maintenance costs.

Month: 2025-08 — Delivered two core features in radiant-portal with a focus on naming consistency, lifecycle clarity, and downstream data quality. The Normal Germline Bioinformatics Task Type was standardized (renaming across integration tests, handler tests, and database migrations), and the Case Status Lifecycle was refactored by removing 'active' and 'on-hold' while introducing 'in_progress' and 'submitted'. Implemented targeted SQL migrations, updated tests/fixtures, and aligned UI to ensure a consistent workflow and accurate telemetry. These changes reduce ambiguity, improve reporting, and establish a cleaner foundation for future enhancements.

July 2025 was anchored by two core feature streams in radiant-portal that materially improve case analysis and variant interpretation workflows. Case Analysis delivered a Unified Search API with detailed per-case counts, observed phenotypes, and an interpretation flag on occurrences, complemented by enriched Case Entity data (analysis details, classification labels, and related tasks) to streamline workflows and UI presentation. Variant Data Enrichment introduced Exomiser counts, inheritance formatting, and new data facets (frequencies, zygosity), plus a Germline Variant Conditions API to retrieve variant–associated conditions across gene panels for advanced analysis. Overall impact includes faster case triage, richer data for decision-making, and a stronger foundation for phenotype-driven analyses. No major bugs fixed this month.
