Summary
👤
SeniorSebastian Messingfeld is a Solution Architect and Staff Engineer with 11 years of mobile and native-app experience, currently shaping the architecture and delivery of Eurowings' consumer mobile apps. He combines deep iOS expertise (Swift/ObjC), cross-platform work with Flutter, and strong CI/CD and modularization practices to turn complex architectures into production reality. His background spans embedded C++ and desktop clients to modern mobile patterns like MVVM and VIPER, giving him a pragmatic systems perspective beyond typical app development. At inovex he led TDD-driven projects, built reusable UI frameworks, and automated distribution pipelines—skills he now applies to scale a travel assistant app used across the customer journey. Based in Cologne, he pairs hands-on implementation with architecture leadership and public-facing technical mentoring from conference talks and meetups.
