What I'm looking for

I seek senior roles combining software/data engineering and ML with product ownership in cross-functional, impact-driven teams where I can lead projects, mentor engineers, and grow scalable data-driven products.

I am a software engineer and data scientist with a strong foundation in mathematics and applied logic, focused on building scalable backend systems and ML-driven products.

I have led product and technical teams across startups and established companies, designing roadmaps, building B2B products, and implementing predictive models such as student-churn and agricultural risk models.

My technical work centers on Python, FastAPI, Django/Flask, Airflow, RESTful APIs, MongoDB/PostgreSQL, Kubernetes and cloud platforms (AWS, IBM), integrating sensors and data pipelines for production systems.

I publish and research in logic and AI, hold several grants and international experiences, and communicate fluently in Spanish, English and Italian to drive cross-functional impact.
