I am a search and e-commerce consultant with more than 15 years of experience building and tuning large commerce platforms. Mostly I work with SAP Commerce Cloud (Hybris) and search engines like Solr and OpenSearch.

My work spans improving search relevancy, building new search features from scratch, designing and implementing large-scale e-commerce platforms, and tracking down performance bottlenecks. I have a deep interest in the Solr and Lucene ecosystem and follow both projects closely.
