Back to original languageAbout Denis
Visionary entrepreneur with over 20 years of experience applying cutting-edge technologies—artificial intelligence, the semantic web, and advanced decision support systems—to the healthcare, insurance, and legal sectors. Strong background in building and growing technology companies, leading multidisciplinary teams, securing funding, and driving high-impact innovation.
I have managed complex, large-scale technology projects from initial scoping through delivery and deployment, particularly in highly regulated and high-impact domains. My project management experience encompasses defining roadmaps, planning, risk management, coordinating multidisciplinary teams, stakeholder communication, and delivering AI-driven SaaS solutions, ensuring alignment between business objectives, technical constraints, and user needs.
My key technical skills include ontology engineering, knowledge graph design, semantic data integration, and reasoning technologies. I have hands-on experience with OWL, RDF, SPARQL, SHACL, and associated W3C standards, as well as operational knowledge of graph databases and ontology management tools. I also have a strong interest in aligning semantic technologies with AI and data-driven applications.
