PROFILE
Jannik Raskob
Over six months, contributed to the assume-framework/assume repository by building and refining backend features focused on data integrity, forecasting reliability, and maintainability. Delivered fifteen features and addressed critical bugs, including robust input validation, enhanced test coverage, and improved data handling for forecasting and storage modules. Applied Python, Pandas, and YAML to implement validation logic, optimize algorithms, and streamline CI/CD workflows using GitHub Actions. Upgraded dependencies, improved error handling, and introduced comprehensive coverage reporting to support quality assurance. The work emphasized defensive programming, clear observability, and maintainable code, resulting in more stable data pipelines and reliable forecasting for energy modeling applications.

Jan 1, 2026Concise monthly summary for 2026-01: Delivered Pandas Data Handling Stability for assume-framework/assume. Implemented robust empty-value handling by converting empties to strings to maintain data integrity during SQL reads and CSV comparisons; temporarily downgraded pandas to prevent breaking changes while issues are resolved. These changes strengthen data pipelines, reduce data integrity risks, and set the foundation for future improvements.

Oct 1, 2025October 2025 performance summary for assume-framework/assume: Focused on reliability, correctness, and scalable model improvements across provisioning, testing, and forecasting. Delivered default database provisioning for new data sources (datasource.yml) to ensure consistent initial provisioning and updated Docker CLI usage guidance to align with newer Docker workflows, reducing setup friction for new sources. Expanded testing coverage for World interactions, unit calculations, and storage/power validation, including the ability to add existing units to the world, which increases confidence in model behavior and regression safety. Strengthened physical modeling and configuration correctness with mandated negative min/max power for demand units and robust unit parameter validations to prevent invalid configurations. Improved data modeling and forecasting workflows with None-based ramp handling for storage (unlimited ramps) and standardization of forecasting time index using FastIndex, enabling safer extensions and clearer performance analytics. Also introduced a strategy compatibility framework (MinMaxStrategy and MinMaxChargeStrategy) to ensure consistent bidding behavior during unit initialization and operation.
