Over seven months, Jway contributed to the broadinstitute/warp repository by developing and refining genomic data processing pipelines, with a focus on automation, reproducibility, and cloud scalability. Jway implemented features such as region-based variant filtering, per-chromosome VCF generation, and mitochondrial DNA analysis, leveraging technologies like WDL, Python, and Google Cloud. Their work included integrating pipelines with Dockstore, enhancing documentation for user onboarding, and standardizing output naming and versioning to improve traceability. By addressing workflow orchestration and batch processing reliability, Jway enabled more efficient, scalable analyses for large genomic cohorts, demonstrating depth in bioinformatics pipeline engineering and cloud-native workflow management.

October 2025 — Warp: Key feature work and quality improvements focused on documentation and standardized processing. Delivered: - Mitochondria Pipeline Documentation Enhancements: README improvements and fixed minor typos in changelogs for ATAC and Multiome pipelines. - Variant Filtering and QC Pipeline – v9 Update: WDL/script updates to reflect v9 processing, including call rate thresholds, dropped fields, new filter definitions, version bump, and extended worker TTL. Major bugs fixed: none identified as major; minor typo corrections completed in changelogs. Impact and value: - Improves reproducibility and onboarding via better docs, and aligns processing to v9 standards, improving data quality and reliability. - Extended worker TTL reduces job timeouts and improves throughput. - Demonstrates proficiency with WDL, pipeline scripting, and documentation tooling.

August 2025: Expanded Warp's genomic workflow suite with mitochondria-focused pipelines integrated into Dockstore, introduced a PCA analysis pipeline for unlabeled genomic data, and added an optional aligned ATAC BAM input to skip explicit alignment across ATAC, Multiome, and PairedTag workflows. These deliverables broaden analysis coverage, reduce unnecessary processing, and improve deployment reproducibility through Dockstore exposure and versioned changes. No critical defects were reported; staging promotions and tool-version updates improved reliability and traceability. Technologies demonstrated include WDL, Dockstore integration, BGZ VCF processing, HWE-normalized PCA with visualization, and ATAC/Multiome/PairedTag orchestration, with cross-domain enhancements for mtDNA, HLA genotyping, and QC workflows.

July 2025: Delivered targeted region-based variant filtering and QC for AoU VCF in broadinstitute/warp. Added optional start and end position arguments to the Python script and WDL workflow to enable region-restricted filtering and QC, refining variant selection with adjusted filtering thresholds. This work improves data quality for AoU analyses, enables precise, region-specific cohort processing, and lays groundwork for scalable, reproducible AoU data handling. Committed as 28525075a4f2671bf3eeed650affa757fe7d596e with message 'Jw subset aou vcf by region (#1626)'.
