At Up Outsourcing, I work on web and mobile products for clients in Brazil and the United States. For ProPlans, I developed Symfony backend features alongside React and React Native apps, including background processing for large file uploads.
At HCosta, I maintained and extended a debt collection system used by 3,000 to 4,000 people at the same time, and helped build a separate application for bulk bank data imports. I also turned spreadsheet-based planning and feasibility calculations into business rules in a Symfony application for LIBBS PRO.
