David Magraner Villalba
Analytics Engineer. Former BI Team Lead. I build the stack, run the team, and ship the insight.
50% AWS cost reduction at Atheneum Partners through warehouse redesign and query optimization. Production dbt + Snowflake models at Enpal. MSc in Economics — the kind of background that means I understand what the numbers actually mean.
Currently open to Analytics Engineer, Data Lead, and Senior Analyst roles in Berlin and remote-EU.
