What I'm looking for

I'm looking for a role where I can contribute to impactful projects in a collaborative, inclusive environment. I value healthy, growth-driven workplaces that support autonomy, learning, and innovation. Open to different industries, I seek opportunities with a strong culture and the flexibility to work remotely from anywhere.

I'm a hands-on and impact-oriented data professional with over 5 years of experience in data science, analytics, and software development. My career spans startups, public institutions, and large enterprises like Dell Technologies and Gertec, where I've consistently delivered practical solutions that bridge business needs and technical execution.

My expertise includes Python, SQL, and tools like Pandas, FastAPI, LangChain, LangGraph, Streamlit, Spark, Databricks, Keras, and Scikit-learn. I’m proficient with relational databases (PostgreSQL, MySQL), NoSQL (Neo4j), and vector databases (ChromaDB), and experienced with Git, GitLab, and CI/CD pipelines. I also work with Power BI and Tableau for data visualization and have hands-on experience with GCP and AWS.

I’ve built scalable data pipelines, forensic ETL workflows, RAG systems with LLMs, and integrated APIs and vector search engines for real-world deployments. My focus is always on creating robust, efficient, and meaningful systems. I also co-authored a peer-reviewed paper on machine learning in healthcare, showcasing my ability to merge academic rigor with applied innovation.

Bachelor’s degree in Information Technology.
Pursuing a second degree in Artificial Intelligence.
Fluent in English and Portuguese; intermediate in German.
