Work History
Python Developer
Independent Portfolio Work
01.2024 - Current
- Data Integrity & Pattern Analysis: Used Python to scan large datasets. I focused on identifying 'suspicious' anomalies and patterns that standard filters usually miss.
- Automated Financial Reporting: I built a custom tool to handle tax liability math. It's designed to cut down on human error and speed up what used to be a very manual, slow process.
- Excel Bridge: Created workflows that allow Python logic to talk directly to Excel spreadsheets, automating bulk data entry tasks.
- Inventory Intelligence: Designed a script that doesn't just track stock but uses logic to flag when levels are unsafe, helping avoid revenue loss from stockouts.
- Handled the end-to-end development of 20+ Jupyter Notebook projects centered on business automation.
