Agentic Engineer · iOS & macOS · Scrum & SAFe
I have been building apps for Apple platforms since 2007 – for products like RTL+, Eurowings, Lufthansa and HRS, most recently for Germany’s electronic patient record at IBM. Today I build AI software factories: agent pipelines that produce software for iOS, Android, web and backend. I own architecture, quality and delivery – the agents write most of the code.
Today
I no longer write software line by line – it is produced by a factory of specialised AI agents. My experience as an iOS engineer and Scrum Master lives in the guard rails: precise specifications, strict quality gates and a process that ships working software every day.
Write requirements, architecture and acceptance criteria that agents can reliably work against.
Agent teams build features for iOS, Android, web and the Supabase backend – in parallel and traceable.
Automated tests, code reviews and quality gates decide what reaches the main branch – not gut feeling.
CI/CD, infrastructure and releases run through the same pipeline – from commit to App Store.

FAQ
From 1 January 2027 – on-site in the Cologne area or remote, in German or English. Feel free to get in touch now so we can plan the project in good time.
An agentic engineer has software produced by specialised AI agents and steers that production: writing specifications and architecture, defining quality gates, reviewing results and owning delivery. I call this setup an AI software factory.
Yes. iOS and macOS with Swift and SwiftUI have been my core since 2007 – from HRS and Lufthansa to Eurowings, RTL+ and the ePA at IBM. Agents speed up implementation; architecture, code reviews and critical parts stay in my hands.
iOS and macOS (Swift, SwiftUI, Combine, HealthKit, Core Bluetooth), Android, web apps, Supabase backends (Postgres, auth, storage, edge functions) and DevOps with CI/CD (GitLab CI, Jenkins, Fastlane, Xcode Cloud) and container deployments.
Through precise specifications and acceptance criteria, automated unit, UI and snapshot tests, code reviews and quality gates in the CI pipeline – plus security know-how from the ePA project: secure development lifecycle and OWASP Top 10.
Yes. I am a SAFe 5 Advanced Scrum Master, Certified Agile Leader and Certified ScrumMaster, have been Scrum Master for iOS and Android teams, supported the agile transformation at Eurowings and worked as team ambassador in the SAFe setup at RTL+.
Yes. Until October 2026 I worked on the electronic patient record (ePA) at IBM – against gematik specifications, with regular training in data security, privacy and secure software development.
