What I'm looking for

I want a remote role in Mexico in data analysis or data science where I can build robust pipelines, analyze complex data, and support impactful, research-driven decisions.

I am a data engineer and data scientist with experience in data collection, cleaning, analysis and visualization across healthcare and B2B telecoms. I have applied Python, SQL and Power BI to large-scale projects, supported 70K users in production, and collaborated with medical researchers to extract insights on brain cancer progression.

I deliver reliable pipelines, reusable SQL scripts, automated processes and clear reporting to support data-driven decisions. I seek to contribute technical rigor, cross-functional communication and a passion for impactful research-driven analytics.
