Data Analyst & AI at Accenture, helping deliver an SMS retry solution that generated over BRL 400K in a month.

At Accenture, I work on a revenue project for a major telecom carrier, analyzing more than 1 billion SMS records each month. I helped deliver an SMS delivery retry solution that generated over BRL 400K in a single month, and I use statistical tests to distinguish real effects from noise.

At PwC Brazil, I automated an Alteryx workflow for a 7 billion-record banking dataset and built a Power BI dashboard to track incidents. I also automate client workflows with LLMs and agent orchestration, from data checks to presentation decks.
