Acerca de Héctor

I am a data professional with experience across data engineering, analytics, automation, and process improvement. My background combines strong SQL skills, Python development, dashboarding, and cloud-based data workflows, with a practical focus on building solutions that make data more reliable, useful, and scalable.

I have worked on ETL development and migration, data quality controls, reporting, dashboard creation, process automation, and analytical use cases, both in regulated environments and in business-oriented teams. My experience includes tools and technologies such as SQL, Python, DBT, Google Cloud Platform, Looker, GitLab, and Oracle-based environments.

What defines my way of working is that I do not just build technical solutions — I also identify inefficiencies, simplify complex processes, and help teams adopt better ways of working. I am comfortable moving between technical implementation and business needs, acting as a bridge to ensure that data projects deliver practical value.

I can help companies with tasks such as building or improving data pipelines, automating repetitive processes, creating dashboards and reporting solutions, improving data quality checks, and supporting teams in making better use of their data tools and workflows.

    At CaixaBank, I have been working in the risk data area, combining data engineering, analytics, and process improvement. A key part of my role has been migrating and modernizing ETL processes from legacy Oracle/SAS environments to more scalable solutions using DBT and Google Cloud Platform.

I have also supported the adoption of new tools and better ways of working across teams, training colleagues and creating documentation for tools such as DBT, GitLab, VS Code, and AI-assisted workflows.

    Overall, my work has been centered on building reliable data solutions, improving processes, and helping teams work in a more scalable and efficient way.
