He has deep expertise in search, information retrieval and full-text engines (Solr, Elasticsearch, Meilisearch, Typesense) and a strong track record migrating and modernizing legacy PHP/Symfony stacks to current PHP versions and cloud-friendly architectures. At Liip he combined hands-on backend development, system architecture and people leadership—leading a six-person cross-functional team and steering multi-country digital transformation programs. An open-source contributor, he has fixed compatibility and API issues in notable projects such as Elastica, Solarium and an Elasticsearch Learning-to-Rank plugin, demonstrating care for long-term maintainability. He pairs academic rigor (Master’s with honors and PhD-level research in IR) with pragmatic product delivery and occasionally implements geo-spatial and ML-driven search experiments. Quietly versatile, he moves between low-level performance fixes and high-level system design while keeping documentation and developer UX in mind.
