Working on the development of batch systems that process millions of data records daily. In my day-to-day activities, I use COBOL DB2, COBOL CICS, SQL, and JCL, applying Systems Analysis and Software Engineering techniques to define efficient solution architectures. I closely collaborate with stakeholders to elicit, define, and validate functional requirements, ensuring clear communication and alignment throughout the projects. My responsibilities also include writing and maintaining technical documentation, as well as updating and maintaining systems to ensure their continuous operation after deployment.

I worked on the integration of ERP systems with the company's e-commerce platform, using Python to develop and maintain batch load scripts. Each integration required the validation, formatting, and loading of thousands of products per client. Occasionally, I used Bash scripts and internal procedures in the database to efficiently perform the integration. Additionally, I contributed to the development of the customer portal. On the back end, I worked with Python and the Sanic framework to create robust and scalable APIs. On the front end, I used Angular to develop intuitive and responsive user interfaces, providing an optimized experience for end users.
