Search & E-Commerce Consultant

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 ranges from improving search relevancy and building new search features from scratch to designing and implementing large-scale e-commerce platforms and tracking down performance bottlenecks.
