About

I hold a degree in Systems Analysis and Development and I'm studying Software Engineering, with hands-on training in algorithms, data structures and Linux at 42 Rio. I'm a Business Intelligence intern at Grupo LLE, where I work with ERP data in SQL, automate processes in Python and build internal desktop and web applications.

I'm also studying Java and Spring Boot to build RESTful APIs. Advanced English (C1). I'm looking for an internship or junior role in software development.

Projects

Automation Panel

Grupo LLE · 2026

The problem: 9 business intelligence and sales routines were done by hand, one spreadsheet and one e-mail at a time.
What changed: A single-window desktop app with a real-time log that anyone on the team can use. The sales campaign routine went from over 1 hour to 5 minutes.

Marketing Hub

Grupo LLE · pair project · 2026 - present

The problem: Marketing work was scattered across Trello, monday, a calendar spreadsheet, a yearly planner and design requests over WhatsApp.
What changed: A web platform for the group's 3 brands, each with its own isolated data. I built the events calendar, the new campaigns screen and the real-time change alerts.
