Summary
🤩
Rockstar🎓
Top SchoolUlysse Ha is a Group AI Portfolio Manager in Copenhagen with 11 years of cross-functional experience applying engineering, product and research skills to enterprise transformation at a global FMCG. He leads development of the company’s first manufacturing LLM across 80+ factories, translating generative AI pilots into measurable COGS savings while training executives and staff on GenAI adoption. Formerly a product owner and digital graduate, he has repeatedly delivered high-impact internal platforms and governance for large, multi-market programs across Europe and Asia. A hands-on backend developer and active open-source contributor, Ulysse has worked on core OCaml projects (compiler, dune, merlin) and production backends like Jellyfin, showing deep technical fluency in compilers, build systems and server-side engineering. He combines social-science-informed user research with rigorous engineering practices—a blend that helped him spot and scale practical AI use cases where others focus only on tech novelty. Pragmatic and curious, he’s as comfortable prototyping low-latency technical fixes as he is aligning VPs on portfolio-level AI strategy.
