Argentina

Message

At ZARIS Consultora, I diagnose and redesign client data models to align measurements with business objectives. I build Power BI dashboards and end-to-end ETL pipelines, define KPIs and OKRs, and provide interpretation guides to support decisions.

At the Municipality of Vicente López, I created a municipal KPI system from scratch, including its data model, ETL processes, Power BI visualizations, and interpretation guides for senior leadership.

I supported the Chief of Staff with monthly operational reports used directly by the Mayor. I also developed a Management Monitor covering digital interaction, citizen requests, and survey feedback.

Earlier, at the Municipality of Vicente López, I implemented the CONRENDI digital payment verification system, improving auditability and eliminating paper archives. I also led development of a collections-management dashboard with CECOM, increasing commercial debt recovery by 69% and on-time payments by 65% year over year.
