Data enthusiast driven by a relentless curiosity to uncover hidden patterns and insights within vast datasets — transforming raw data into strategic business decisions that propel growth and innovation.
I'm Luis Geovanni Sainos, a Data Analyst and BI Developer based in Mexico City. My work sits where rigorous analysis meets clear storytelling — extracting data with SQL, shaping it with Python & Pandas, and surfacing the signal through Power BI dashboards and DAX measures.
I'm driven by a relentless curiosity to uncover the hidden patterns inside large datasets — and a conviction that good analysis should end in a confident business decision, not just a chart.
— Insight is only valuable when it moves the business.
From raw extraction to executive-ready dashboards — the tools I use to take a question from data to decision.
Fluent in SQL & Python — from window functions to full data pipelines.
CTEs, subqueries and window functions for analysis at scale; Python & Pandas for cleaning, reshaping and automated reporting.
Data modeling, relationships and DAX measures that turn messy sources into KPI dashboards executives actually use.
Cloud-scale querying & warehousing on Google BigQuery.
Clear, publication-grade charts that make the story obvious.
Data cleaning, validation and preparation with a strict focus on data integrity — because dashboards are only as trustworthy as the data behind them.
Four end-to-end analyses across BI, SQL, Python and Excel — each one chasing a real business question to a clear conclusion.
Pulled, joined and managed data with SQL across sources to build reliable, analysis-ready datasets.
Created repeatable reports and analyses using Python & Pandas to remove manual, error-prone steps.
Designed Power BI dashboards and DAX measures that surface KPIs and trends for stakeholders.
Turned spreadsheet analysis into clear narratives, communicating findings to non-technical audiences.
Have a dataset, a dashboard, or a question that needs answering? I'd love to hear about it — let's talk.
