@nicolsdaz
I turn business data into decision-ready insights using SQL, Python, Power BI, and predictive models.
ArgentinaWhat I'm looking for
I've built decision-ready dashboards and customer segmentation at Conci, a John Deere dealership, helping management refocus commercial priorities toward higher-margin parts and service segments. My Power BI reporting supported 10 directors, managers, and HR leaders with sales, after-sales, and parts KPIs.
More recently, I've delivered production automation for accounting firms serving 60+ clients, built a text-to-SQL agent for Argentine agriculture, and developed end-to-end credit-risk and AWS data warehouse projects. I combine SQL, Python, Power BI, business process understanding, and clear communication to turn complex data into practical decisions.
