Freelancer profile translated to English.
Back to original languageAbout Ignacio
I have more than 10 years of experience working with data in environments where errors have a real cost: duplicate records leading to claims, critical nulls breaking processes, referential integrity that no one had validated.
My work has always been at the intersection of engineering and business. I don't just build pipelines or write queries—I analyze what's failing in the data, why it's failing, and what impact it has on the decisions the company makes.
I work mainly with advanced SQL and Python in Oracle and SQL Server environments, specializing in data quality, PL/SQL, and database architecture. AWS Certified.
I have managed migration, data loading, quality validation, and pipeline design projects in sectors with complex data and high volumes.
Available for data audit, quality review, pipeline design, or occasional technical support projects. I work remotely or in person in Madrid.
