What I'm looking for

I'm open to remote senior data roles.

At Afiniti, I own the analytical skill library behind Afiniti Intelligence, validating its output against ground-truth SQL before release. I also run SQL and Python reconciliation that validates client performance gains and supports on-time pay-per-performance billing.

At BV Financeira, I developed lifecycle analytics behind cross-sell, up-sell and retention campaigns that generated R$350M in originations, and later rolled out Tableau reporting to 1,600 users. I also built FII Guia, a free analytics platform for Brazilian retail investors, with a daily AI analysis pipeline that verifies figures against source documents.
