I’m an independent freelancer focused on solving well-defined data and technical tasks with a structured and reliable workflow. I can help with Python automation, Excel and CSV data cleaning, data processing, deduplication, debugging, QA and testing. My approach is simple: understand the requirement, preserve the original data or code, make controlled changes, verify the result and document what was done. I’m especially suited for small and medium-sized projects involving data cleanup, file transformation, Python scripts, automation, debugging and technical validation. For unusual or more complex projects, I review the requirements first to confirm the scope before starting.
