Message

At DataSeed by Iexlog, I deliver enterprise data platforms, governance, and applied AI for clients across the US, Chile, and the wider region. For a US retail migration, I reverse-engineered 141 stored procedures into production AWS Glue jobs and reconciled 25 financial KPIs 1:1 at each client sign-off.

For a Chilean copper-mining client, I built environmental compliance visibility across four divisions, including a 28-KPI weekly matrix and real-time GIS map. I’ve also delivered governed lakehouses and analytics for clinical-trials technology, HR tech, aviation, and SaaS; I work to ensure figures reconcile to source and platforms are documented and operable by the client’s team.
