• Version control & collaboration: contribute via git (branching, pull requests, code review), and coordinate handoffs.
   

Data Operations and QC:

• Manage end-to-end data flow: requesting data from BDM, tracking delivery, organizing on internal servers with proper folder structure and data cut documentation.

• Prepare and send sample lists to sample management and other departments upon request

• Works with scientists to harmonize heterogeneous formats, for the ongoing ingestion of biomarker data into common data formats

• Reproducibility & QC: maintain run logs, validate outputs against expected formats/metrics, and ensure raw vs processed outputs are stored according to team conventions.

• Support project & deliverable trackers: maintain a robust tracking system for analysis/pipeline deliverables (status, owners, due dates, dependencies, links to locations), and provide concise visibility for stakeholders.

Open Source Code Development:

• Claude Code sharing and optimization: maintain a reusable library of prompts/snippets/skills for common tasks (e.g., data viewer creation), define standards (style, testing, documentation), and provide light enablement to ensure consistent AI-assisted workflows.
