What I'm looking for
I am a GIS Data Engineer with a strong background in data infrastructure and engineering, having transitioned into this role after five years of experience.

I take pride in my ability to enhance data accuracy and optimize processes, as demonstrated by my work in the Brazilian agribusiness sector, where I ensured geospatial quality control and significantly reduced errors.
Throughout my career, I have developed a proficiency in tools such as QGIS, PostGIS, and Python, which I leverage to create efficient data pipelines and optimize workflows.
