PROFILE

Felix Mölder

Felix Moelder developed and maintained bioinformatics workflow components in the snakemake/snakemake-wrappers and conda-forge/staged-recipes repositories, focusing on reproducibility and stability. He engineered graph-based wrappers for the VG toolkit, enabling automated indexing and haplotype-aware mapping in Snakemake pipelines using Python, Shell, and YAML. Felix upgraded toolchains, pinned dependencies, and refactored wrappers to support new input types and output logic, improving workflow flexibility. In conda-forge, he packaged Python SDKs and command-line tools, enhanced license compliance, and managed build system configurations. His work demonstrated depth in dependency management, workflow development, and package management, resulting in robust, maintainable solutions for scientific computing.

February 2025: Focused on stability and enabling haplotype-aware graph workflows in snakemake-snakemake-wrappers. Key deliverables include DataVzrd upgrade to v2.48.0 with environment pinning and a refactor of the vg giraffe wrapper to support haplotype-sampled pangenome graphs, including new input parameters and improved output naming/bundling. No critical bugs fixed this month; impact centers on improved reproducibility, stability, and readiness for broader haplotype-aware analyses. Technologies demonstrated: dependency management, conda environment pinning, wrapper refactoring, and output/resource naming design.

In November 2024, delivered and refactored two graph-based wrappers in the snakemake/snakemake-wrappers repository that materially improve reproducibility and scalability of vg-based workflows. Implemented the VG Autoindex Wrapper for automatic indexing (giraffe subcommand) with environment setup, metadata scaffolding, and tests; refactored to generalize the wrapper to support multiple vg subcommands (giraffe, map) with workflow decisions driven by output extensions. Added the VG Giraffe Read Mapping Wrapper with environment definitions, a test Snakefile, and a Python wrapper to handle mapping and optional sorting of BAM/SAM/CRAM outputs, enabling configurable sorting. These changes streamline graph-based alignment in Snakemake pipelines, reduce setup time, and improve reproducibility across teams.
