Summary
👤
Senior🎓
Top SchoolJavier Cádiz is a Staff iOS Engineer based in Madrid with 12 years building high-quality mobile products across fintech, startups, and enterprise banking. He brings full-stack sensibilities to iOS development—architecting VIPER and Coordinator-based apps, optimizing performance, and automating analytics and migrations to modern Swift toolchains. At Qonto and Openbank he delivered scalable, data-intensive features and mentored teams to raise code quality through reviews and pair programming. Early experience as a co-founder in Cuba gave him hands-on infrastructure and offline-first expertise, and he frequently bridges native mobile with backend services like GraphQL, Firebase, and serverless microservices. Pragmatic about testing and performance, he treats being full-stack as a mindset: curious, end-to-end focused, and driven to make mobile the bridge that brings technology to everyone.
