About Me

I hold a degree in Electrical Engineering from the Federal University of Espírito Santo (UFES), with an emphasis on Computer Science, along with technical backgrounds in Electrotechnics and Systems Analysis.

I have a research background in NLP and AI, having built full pipelines including tokenization, Named Entity Recognition, and integrating Large Language Models (LLMs) to generate automated summaries and visual insights.

Currently, I work as a Software Engineer handling mobile (Flutter/Native Android), backend (Spring Boot Kotlin), and databases (PostgreSQL). I've built solutions across an ecosystem of 8+ apps present in over 5,700 establishments across Brazil, managing the full app lifecycle and cloud infrastructure (AWS).
