Certified in Cloudera and Hortonworks, he has a strong Hadoop background while modernizing pipelines for real-time use cases at companies like Joyn and relayr. An active contributor to Apache NiFi, he has fixed core processors and improved bootstrap behavior, showing a propensity for improving open-source tooling that powers data flows.
