At Almarena, I build the backend of a construction project management system used by the Purchasing and Real Estate teams. It brings project progress, supplier offers, and invoice status together in one place.

I implemented supplier invoice OCR with AWS Textract and validation against ARCA web services. The OCR runs asynchronously in an isolated thread pool, with timeout and error handling.

I also implemented validated bulk uploads from Excel and develop REST APIs, write unit tests with Mockito, and generate PDF documents for the supplier workflow. I work with end users and the front-end team to gather requirements and validate features in demos.

For my Mappas capstone project, I contributed to a web and mobile platform for rural land management and traceability, including offline support and external weather and soil data. I graduated in Information Systems Engineering from UTN FRBA.
