Jossef Roncal — Machine Learning Engineer & Software Architect
Machine Learning Engineer & Software Architect
I build AI systems that are allowed to touch real records: measured, auditable, and shipped to production.
Engineer with eight years of building and running a software and fiduciary company in Geneva, and a Master of Science in Engineering (HES-SO), completed in 2026, in Software Engineering. I work where machine learning meets systems of record — accounting, documents, compliance — and I care as much about what a model costs and how it is verified as about what it can do.
