PROFILE
Sharla Gelfand
Sharla Gelfand developed and enhanced data access and analysis workflows for the eopf-toolkit/eopf-101 repository, focusing on geospatial and environmental datasets. Over four months, Sharla built R tutorials for interacting with the EOPF Zarr STAC API, implemented dynamic catalog item retrieval, and introduced benchmarking for SAFE versus Zarr data formats. She improved documentation clarity and onboarding by refining R Markdown and Jupyter Notebook content, adding visualizations, and automating deployment with CI/CD pipelines and Docker. Her work addressed data pipeline reliability, persistent dataset management, and reproducible analysis, demonstrating depth in R programming, data visualization, and technical writing for robust, maintainable scientific tooling.

Mar 1, 2026March 2026 monthly summary for repository: eopf-toolkit/eopf-101. Focused on delivering automated deployment capabilities, improving data pipeline reliability, expanding documentation, and introducing a data-format benchmarking tutorial with practical performance insights. Key features delivered: - CI/CD deployment workflows for the EOPF project: Implemented CI/CD workflows to manage Docker images and render documents, enabling automated, reliable deployment pipelines for the EOPF project. (Supported by commit 5a154ae4437ad018de65e534539b55a81f401865) - Documentation enhancement: pre-rendered GIFAPAR plot image to improve documentation visuals and user experience. (Commit 8d5237a3724627ddb7b3d8c791e000786b630bd6) - SAFE vs Zarr tutorial and benchmarking in R: Added a tutorial comparing SAFE and Zarr data formats, updated the tools/index, and included benchmarking code for performance comparisons of data retrieval methods. (Commits f0a153319861a5d1539118b83abfe5eea508187f; c9e064d3e09f88038b30e0200539140958315430; 02df05120523484ee8d59c99cba3bb736f88e4c5) Major bugs fixed: - Sentinel-2 quicklook restoration and data pipeline fix: Restored the Sentinel-2 quicklook example in the R chapter, ensured the use of persistent datasets, and fixed data pipeline issues including environment variable handling (PROJ and GDAL). (Commit 5ad8d781115ab370414ea9a08b94c64e99ae4959) Overall impact and accomplishments: - Strengthened deployment reliability and repeatability through CI/CD, reducing manual steps and downtime in production workflows. - Improved data pipeline resilience for Sentinel-2 imagery with persistent datasets and corrected data flow, ensuring reproducible results for readers and users. - Elevated documentation quality with visual aids and an actionable benchmarking tutorial, speeding value delivery to users and contributors. Technologies/skills demonstrated: - CI/CD pipelines, Docker, and deployment automation - Data engineering practices: persistent datasets, environment configuration (PROJ, GDAL) - R programming, Quarto-based documentation, and data format benchmarking (SAFE vs Zarr) - Documentation best practices and technical storytelling with reproducible examples
