I have a positive attitude and technical skills to help you find insights and relevant information in your datasets, for which I guarantee direct communication and clear deliverables in each project.

Technical competencies:
Tools: SQL, Power BI, Advanced Excel, Tableau, Data Modeling, Python (pandas, numpy), Alteryx.

Soft skills: effective communication, clarity in deliverables, documentation, proactivity, business vision.

I have a business-oriented profile, which allows me to communicate effectively with technical and non-technical profiles, as I perfectly understand both worlds. Likewise, I have a strong orientation in the financial, retail, and HR industries, but I am open to all industries, as I enjoy learning and adding value without limitations.
