PROFILE
Imedina
Worked on the opencb/opencga repository, delivering features across genomic data analysis, pipeline integration, and deployment reliability. Developed and expanded NGS and Affymetrix pipelines, integrating multi-aligner support, variant calling, and meta-analysis tools to improve clinical and research workflows. Applied Python, Java, and Docker to enhance backend processing, containerization, and data quality, including filtering undesired alleles and embedding traceability in VCF outputs. Refined logging and configuration management to streamline operational clarity and reproducibility. Focused on robust API development, REST integration, and cloud deployment, the work emphasized maintainability, scalability, and accurate data processing for bioinformatics and clinical genomics applications.

Jan 1, 2026January 2026 performance summary for opencga: Delivered deployment and data-quality enhancements with a focus on reliability, reproducibility, and traceability. Key features include packaging pyopencga into the OpenCGA Docker image and switching to URL-based apt2 binary downloads to ensure the latest binaries are used. In the Affymetrix Axiom pipeline, implemented data quality improvements by filtering undesired reference/alternate alleles in VCFs and added job IDs to VCF paths for enhanced traceability. These changes reduce installation variability, improve data integrity, and provide clearer audit trails across pipelines.

Nov 1, 2025November 2025 (2025-11) monthly summary for opencga. Delivered end-to-end integration of the Affymetrix microarray pipeline within the NGS framework, including REST endpoint alignment, improved sample handling, parameterization, and a best-practices workflow covering QC, alignment, and variant calling. Implemented CLI batch processing via a new --samples-file option and consolidated RD Interpreter thresholds with a dedicated config for increased accuracy. Hardened containerization and tooling: cleaned Dockerfiles, extended external-tools, and updated images to better support NGS/OpenCGA pipelines. Stabilized the pipeline by fixing critical Affy REST endpoint class issues and related affy pipeline regressions. These capabilities collectively improve reproducibility, scalability, and speed for microarray-enabled NGS analyses, enabling faster onboarding of samples and reliable results.
