What I'm looking for

I’m available immediately for remote work from Mexico City. I’m taking on independent data science projects while completing my master’s thesis.

At ProFuturo, I developed Power BI dashboards for intraday monitoring of strategic KPIs and designed ETL processes in SAS and SQL to load production Oracle databases. I also led the design and optimization of relational databases supplying indicators to the E-commerce division.

As a Data Analyst at ProFuturo, I analyzed client retention across call-center agents and designed strategies to distribute top performers across teams. I implemented regression and classification models to predict trends and segment client portfolios.

At Dresden Partners, working with client Mobility ADO, I built Looker Studio and Power BI dashboards and automated data extraction and reporting. I also developed predictive models for sales behavior and seasonal trends, plus sentiment analysis to guide SEO strategy and user engagement.

As an independent consultant, I built a RAG query system for Terminal Fidel Santiago using project documentation and Puerto Rico regulations, and audited structural calculations with Claude Code. My M.Sc. thesis project, Q-Auhtli, applies a hybrid quantum-classical neural network to audio anti-spoofing.
