CI/CD ExpertRadu brings over 13 years of experience in mobile app development with a particular focus on build systems and continuous integration pipelines. As a former Mobile Guild Lead at Deloitte Digital and Staff iOS Engineer at Qonto, his expertise has helped companies reduce their build times from hours to minutes, transforming developer productivity and release velocity.
I believe that developer experience is directly tied to product quality. When engineers spend less time waiting for builds and more time solving problems, everyone wins – the team, the company, and most importantly, the users. My goal is always to create systems that eliminate friction, boost productivity, and make development enjoyable again.
