Freelancer profile translated to English.

Description

Computer Engineer and MBA from IE Business School with 20+ years delivering end-to-end analytical solutions at Amazon, Accenture, and the European Investment Fund — a profile that combines technical depth with business vision.

If your company needs to transform data into impactful decisions, with rigor and on time: let's talk.

I work at the intersection of business and data. After more than two decades in top-tier organizations, I have spent the last two years as an independent freelance consultant — combining corporate world knowledge with the agility of someone who integrates quickly and delivers value from day one.

Top 3% worldwide of verified Business Analysts by Toptal. Stack: Power BI, Tableau, SQL, Python, Snowflake, SSAS.

I am a solid partner for analytical projects: end-to-end ownership, proactive communication, and meeting deadlines as the norm, not the exception.

HOW I WORK

01 · Discovery— Initial sessions to map data sources, key questions, and objectives. The focus: understanding what decisions you need to make and what's preventing you today.

02 · Build— I build pipelines, data models, and KPI logic. No technical burden for your team. Result: reliable dashboards and aligned metrics.

03 · Continuous Delivery— Updated dashboards, performance summaries in business language, and support for new questions.

AI-augmented delivery— I integrate the latest AI tools to accelerate exploration, code, anomaly detection, and insights. More speed, same rigor.
