About

Self-taught developer who loves solving problems. It started young with videogames and small pages or scripts built out of curiosity.

The real leap came in 2024 with the dual-education model: I proposed automations ranging from Kotlin inventory apps to Python backends and IoT sensor integrations. That work won 1st place nationally at the VET-Excellence Dual Award 2026 with Káiros.

Now studying ICT Engineering, and a certified Industrial Productivity Technician (Conalep, dual model), where my process background was born. Looking for a remote team to contribute and keep growing.
