Data Engineer | Data Scientist | Cloud Development

I am an analytical professional with a unique trajectory, having transitioned from Data Scientist at Lombard Insurance to specializing in Data Engineering and Cloud Development. My foundation in production data science gives me crucial insight into modeling needs and data quality requirements. I leverage this experience, combined with intensive training in ETL pipeline design, containerization (Docker), and full-stack data solutions, to build robust data infrastructure. I am driven by automating complex data workflows and am currently seeking Data Engineer roles where I can build reliable, scalable data platforms using Python, SQL, and Cloud technologies.
