PROFILE

Janne Sinivirta

Janne Sinivirta developed and released two packaging recipes over two months, focusing on robust build automation and distribution for scientific software. For the conda-forge/staged-recipes repository, Janne created a conda-forge recipe for the daffy package, aligning with conda-forge conventions, updating Python version requirements, and enhancing test coverage by integrating dependencies like pandas and polars using Python and YAML. In the bioconda/bioconda-recipes repository, Janne delivered a new recipe for fastqpacker, a speed-first FASTQ compressor, implementing build and test scripts with bash scripting. The work demonstrated careful attention to packaging standards and reliable, CI-ready software distribution.

December 2025 monthly summary for conda-forge/staged-recipes focusing on the Daffy packaging and release efforts. Delivered a conda-forge packaging recipe for the daffy package, aligned with conda-forge conventions, added testing dependencies, and updated version/URLs to ensure reliable builds. Implemented python_min-based Python version alignment and bumped the minimum Python to 3.10 to satisfy narwhals requirements. Upgraded daffy to 2.2.0. Added test dependencies (pandas, polars, pydantic) to improve test coverage and build reliability. These changes enable seamless distribution via conda-forge and position the package for stable releases.
