Message

At Adyen, I design, implement, and support a data platform, working with infrastructure and data customer teams to keep applications stable and performing well. I’m responsible for the Hadoop ecosystem holding 25+ petabytes and Kubernetes clusters running data pipelines, machine learning workloads, and analytical reports.

At Itility, I integrated analytics tools into an Azure-based self-service platform and supported Hadoop availability and performance. I also planned and implemented tools such as Knime AP and Spotfire, helping users transition and migrate workflows.

Earlier, at AmeXio, I helped migrate data transformations to Spark and Hadoop. At Farfetch, I optimized Hadoop performance and stability, supported Business Intelligence and Data Science teams, and improved data quality, security, and information availability.
