Raphael Voellmy

Full-stack software engineer with 13+ years of experience building software for Swiss banks, insurers and startups – and for my own company. I do my best work close to customers: understanding the business, shaping requirements with stakeholders and turning them into software that ships.

Highly enthusiastic about AI-driven software engineering and process automation. Deep domain knowledge in Swiss financial services (ZKB, Finnova, AXA, UBS). Former Head of Frontend and lead developer in startups, Scrum master at ZKB, founder of i42 GmbH. Native German, fluent English.
