Sobre mí
Most dashboards don’t fail because of visuals.
They fail because the data foundation is broken.
I’m Jack, an Analytics Engineer with 5 years of analytics experience. I specialize in turning messy SQL databases into clean, structured, reporting-ready systems.
If you’re experiencing:
• Slow dashboards
• Conflicting metrics
• Duplicate or inconsistent data
• Reporting errors
I fix underlying data layer.
I deliver:
✔️ Optimized SQL queries
✔️ Structured reporting models
✔️ Clean warehouse architecture
✔️ Automated pipelines using Python & Airflow
✔️ Clear documentation your team understands
