What I'm looking for

I seek analytic roles where I can build automated pipelines, develop predictive models, and create cross-system dashboards within collaborative, impact-focused teams.

I am an analytical and detail-oriented Data Analyst with hands-on experience extracting, preprocessing, and visualizing complex datasets to inform strategic decisions. I have built automated SQL reporting pipelines, integrated cross-system dashboards, and developed predictive models that improved planning accuracy and reduced operational risk.

At SIATT I managed data for over 14,000 electronic components, created Tableau dashboards combining Protheus and Chronos data, and reduced manual reporting workload by 60% while improving obsolescence planning by 30%. My co-op experience and teaching assistant roles sharpened my ability to communicate technical concepts and deliver measurable productivity gains.

I am passionate about transforming data into actionable insights, optimizing workflows through automation, and collaborating with cross-functional teams to solve high-impact problems. I bring strong technical skills in Python, SQL, Tableau, and Excel, plus multilingual communication in Portuguese, English, and Spanish.
