Relevant iOS Experience

Axel Springer National Media & Tech GmbH / Berlin (12/2023 - Present)

Owned end-to-end delivery of iOS features from discovery to release, including Home Screen widgets that drive about 8% of app traffic.
Built polished native UX in Swift, UIKit, and SwiftUI with strong attention to accessibility, reliability, and measurable customer impact, using TCA for modular product flows.
Improved quality and release confidence through robust CI/CD, code review standards, and a pragmatic "keep it simple" engineering approach.
Consistently optimized our development workflow to adapt quickly to changing requirements, combining Swift concurrency and modular architecture to reduce defects and improve team velocity.
Actively leveraged AI agents in daily development, especially Codex and Cursor, for faster prototyping, refactoring, and review preparation, which increased iteration speed without lowering quality standards.
Delivered work in a trunk-based development style, using feature flags and A/B Tesing, validate impact quickly, and iterate based on real usage data.
Worked closely with product, design, backend, and QA so the best argument wins and decisions are validated by user and business outcomes.

PAYBACK GmbH / Munich (02/2023-07/2023)

Delivered customer-facing iOS features and notification journeys with high reliability and clear product ownership, using TCA for predictable state and scalable feature delivery.
Implemented MFA and account security enhancements, aligning delivery with trust-first principles and production safety.
Migrated key app modules to SwiftUI while maintaining UIKit screens, balancing modernization with stable release execution.
Integrated Airship push notification infrastructure and replaced existing messaging flows with a more maintainable setup.
Contributed to a brand refresh and widget extensions, partnering with design and product to ship polished releases on tight timelines.
Strengthened team delivery quality through active code reviews and clear engineering standards in day-to-day collaboration.

Amsterdam (05/2018-02/2023)

Built and shipped iOS/macOS products with full ownership across architecture, implementation, release, and long-term maintenance.
Created QRCobot with camera-first QR/barcode flows using native iOS APIs, with focus on practical UX and clear user value.
Created OnlySwitch with SwiftUI and TCA; reached 5,500+ GitHub stars by continuously iterating from community feedback and production learnings.
Practiced "never assume" by validating behavior with logging, tests, and observability tooling before scaling features.

Yizhibo (Weibo Group) / Beijing (09/2016-05/2018)

Reduced crash rate from 0.5% to 0.07% through engineering standards, CI/CD, and sustained quality ownership.
Modularized a large iOS codebase with CocoaPods and improved build time by 15%, enabling faster and safer team delivery.
Designed a plugin-based live-stream framework that doubled feature iteration speed under rapidly changing product needs.

Weibo Corporation / Beijing (10/2015-08/2016)

Optimized video playback and feed performance, improving FPS 2x-3x in high-load scenarios.
Reduced playback issues by 60% through A/B testing, benchmarking, and rigorous cross-functional debugging loops.
Contributed to large-scale customer growth by improving autoplay and preload strategies in production, helping save hundreds of millions of EUR in infrastructure costs.
