About

Professional summary

I am a Senior Business Analyst and Data Scientist with experience connecting business strategy, data analytics, and technology to support high-impact decisions. My career has evolved from hands-on technical support and engineering into strategic business analysis, business intelligence, and data-driven transformation.

I have worked in global technology environments, partnering with Customer Support, Customer Success, Product, Risk & Compliance, Operations, Engineering, and executive stakeholders. I translate business requirements into KPIs, dashboards, analytical models, data pipelines, process improvements, and scalable governance solutions.

I bring strong expertise in Python, SQL, Tableau, Azure Databricks, Airflow, Splunk, data modeling, applied statistics, predictive analytics, and automation. My technical engineering background also gives me a structured approach to root-cause analysis, cloud migration, performance troubleshooting, and process optimization.

At Atlassian, I led and supported global analytics initiatives involving customer experience, community health, risk and compliance, productivity analysis, and operational reporting. My work contributed to measurable improvements in mitigation rates, reporting reliability, support demand planning, and strategic decision-making.

I am also experienced in stakeholder management, requirements gathering, process mapping, digital transformation, and training teams to adopt new tools and workflows. I am available for international opportunities and continue developing my capabilities in AI engineering, LLM engineering, RAG, agents, and data engineering.

I am based in Porto Alegre, Brazil, and am interested in senior-level roles where I can combine analytical depth, business partnership, and technical expertise to build practical, data-driven solutions.
