Kamel Bendimerad

Open to mid-level and senior engineering roles

Kamel Bendimerad, Software engineer working on streaming data systems and geospatial software.

I build data pipelines and research tooling on Kafka at UBS Evidence Lab in Kraków. Before that I spent two and a half years leading frontend development on GIS platforms for Polish public administration. One of them runs the City of Gliwice’s public geoportal today.
