Sobre mim
I'm a Python developer focused on data cleaning, validation, and automation — turning messy CSV/Excel files into clean, reliable data you can use. Every script is tested against real edge cases, not just the easy path.
I focus on clear, well-commented code and honest communication, so you always know exactly what was done and why.
Need your data cleaned or a repetitive task automated? I'll deliver something accurate, tested, and easy to use.
