About Juan Sebastian

Do you have data but no information? I transform your disorganized Excels into clear dashboards that help you make decisions.
I am a Data Analyst based in Barcelona, specializing in Power BI and automation with Python. I help companies and video game studios visualize their performance and optimize operational processes.
How can I help you?
📊 Business Intelligence: I design interactive dashboards in Power BI to monitor sales, inventory, logistics, or user/player metrics in real-time.
⚙️ Automation with Python: I eliminate repetitive manual tasks. What used to take you 4 hours in Excel is now done automatically with custom scripts.
🎮 Gaming Analysis: Certified in Unity, I offer data analysis for indie studios (player retention, game economy, technical testing with professional reports).
My experience: I have led process improvement projects, reducing operational times by 70%. I combine analytical rigor with the ability to explain complex data simply.
Tools: Power BI | SQL | Python (Pandas) | Advanced Excel | Unity 3D
Languages: Spanish (native), English (C1 professional)
