Worked on the TampereHacklab/mulysa repository to maintain and enhance the Holvi data import pipeline, focusing on adapting to Holvi’s 2025 export format changes. Updated the import logic to recognize new header names, ensuring ongoing compatibility with evolving data structures. Improved error handling by modifying date parsing to catch missing keys, which increased robustness when processing incomplete input files. Added targeted tests to validate the updated file structure and maintain reliability. Leveraged Python scripting, file handling, and testing skills throughout the process, delivering precise, traceable changes that addressed both feature updates and bug fixes within a short development period.
