PROFILE
Michal Babinski
Developed and maintained advanced bioinformatics workflows in theiagen/public_health_bioinformatics, delivering features for genomic assembly, variant calling, and antimicrobial resistance profiling. Leveraged Python, WDL, and Shell scripting to build modular pipelines integrating tools like Nextclade, Pangolin, Flye, and Clair3, supporting both Illumina and Oxford Nanopore data. Enhanced reproducibility and data quality through Docker-based containerization, explicit version tracking, and robust documentation. Addressed workflow stability by refining resource allocation, input handling, and edge-case management. Improved onboarding and maintainability by updating test suites and aligning configuration files. The work enabled reliable, end-to-end genomic analyses for public health surveillance and research applications.
