What I'm looking for

I'm seeking senior-level roles combining data science, MLOps and software engineering in healthcare or life-sciences, with strong collaboration, research impact, and opportunities to lead platform and LLM-driven projects.

I'm a Computer and Data Engineer/Scientist with eight years building data solutions in academia and industry, focused on healthcare, life sciences and oncology research. I have led teams, created internal Python/R libraries, developed Dockerized tools and APIs, migrated data platforms to Databricks, and delivered ML and LLM solutions that improved analytics, operational efficiency and business outcomes.

I combine hands-on software engineering, data engineering, MLOps and traditional research: developing predictive models for clinical outcomes, implementing LLMs for natural language-to-SQL and RAG workflows, and producing peer-reviewed publications while collaborating with institutions like the National Cancer Institute of Mexico and pharma partners.
