Python Developer at Cervecería Madre Monte S.A.S. who built Z1 Agent, cutting invoice processing time by 90%.

At Cervecería Madre Monte S.A.S., I built Z1 Agent to automate invoicing, inventory, and notifications using Python, Google Sheets, Alegra, and Telegram. It reduced invoicing time by 90%, from 15 minutes to under one.

I also developed payment reconciliation and bank receipt OCR workflows, and optimized an asynchronous invoice pipeline from 50 seconds to 5 seconds for 20 invoices. My work includes a Flask API for real-time inventory and sales, plus operational dashboards covering more than 4,260 historical invoices.
