Profile

I analyse processes, measure them with data and automate them so a business wins and keeps customers. Since 2022 I have worked self-employed as a data and automation analyst: I maintain three systems in production for paying clients I won myself, with 34 automation flows in n8n, API integrations, a CRM and KPI dashboards on real data. One of those analyses showed that 34% of revenue came from returning customers and changed how that client plans their calendar and campaigns. Before that I was a Data Analyst at Datmean (predictive models in Python and SQL) and a process engineer at Grupo Antolín, optimising production and logistics in automotive with +10% efficiency. MSc in Data Science and Business Analytics (IMF, 2022). I am looking for a full-time role where I can contribute from month one and grow long term.

Momentos Mágicos

Paying client

Bookings and payments with a KPI dashboard on real data: repeat customers, occupancy by day and time slot, lead time and turned-down demand. The analysis revealed that 34% of revenue came from repeat customers and reshaped the schedule and campaigns.
