About Kazuichi

I am a Senior Social Listening and Data Consultant at RocaSalvatella (Barcelona), with previous experience in banking (BCP) and BI consulting. I combine Power BI (advanced), Python, SQL, and data governance to build robust solutions: well-modeled, documented, and easy to maintain. My added value is that I don't just "make charts," but I design data stories oriented towards concrete actions: optimizing campaigns, tracking the evolution of key KPIs, detecting problems in time, and measuring results.

How can I help you?

End-to-end Power BI Dashboards: from connecting to your sources (Excel, SQL, APIs, social media...) to publishing and automatic updates.

Data modeling and DAX: creation of measures, custom calculations, segmentations, and comparisons (YoY, MoM, vs. target, etc.).

Automation and data quality: cleaning, standardization, and validation to ensure your reporting is reliable.

Marketing and social media reporting: campaign dashboards, digital reputation, funnel, community, and performance by channel.

Support and training: adapting dashboards to your team, functional explanation, and support to make you autonomous.

If you are looking for someone who speaks your business language, not just the technical one, and can deliver Power BI reports ready to present to management, I will be happy to help you with your next project.
