What I'm looking for

I’m seeking roles where I can design and maintain ETL pipelines, improve data quality, and apply statistical and programming skills in collaborative, growth-focused teams.

I am a data warehouse developer and engineer with hands-on experience designing and maintaining ETL processes, ensuring data integrity, and cleaning and transforming data for reliable analytics. I have built automation solutions as an RPA developer consultant and taught mathematics and informatics, demonstrating strong technical communication and client-facing skills.

With an M.Sc. in Mathematical Statistics and a B.Sc. in Mathematics, I combine statistical rigor with practical programming in SQL, PL/SQL, Python, R, and Matlab to deliver robust data solutions and scalable pipelines that support business needs.
