Building scalable data systems that turn complexity into clarity.
I’m Boubker, a Data and Software Engineer focused on designing scalable, reliable data platforms and pipelines.
I build data systems that make analytics reproducible, performant, and actionable — enabling teams to trust their data and make better decisions.
Outside of work, I enjoy exploring new technologies, reading, gaming, and powerlifting.
