Christian B.-Freelance Product Owner | Product Manager

Re-engaged to own two product streams end to end, from concept and UX design through to AI-assisted implementation.

• Redesigned the offer and follow-up journey across 38 insurance plans, 16 providers, and four age segments, spanning web, WhatsApp, email, and SMS.
• Launched the rebuilt conversion flow in a live A/B test against the legacy version - evaluation still in progress.

Product lead for an AI-native mobile app built from scratch and taken to a working MVP in four months - owning the product track alongside a tech lead and leading a cross-functional team of five engineers (two mobile, backend, AI, DevOps) and a UX designer on all product matters.

• Led the product development of the app (React Native, iOS): an AI assistant that helps users grow their LinkedIn presence and reach.
• Designed the AI content engine: post and reply drafts in the user's own voice, generated from a tone-of-voice model and a personality profile captured during onboarding - tuning the engine on its own output and setting the standard those drafts had to meet.
• Owned product vision, roadmap, backlog prioritization, and MVP scope - deciding what made the MVP and what had to wait.
• Worked directly with the client's C-level executives throughout, translating business goals into product decisions.

Analyzing and redesigning the user journey of the insurance comparison, and building the tracking foundation for the digital sales funnel.

• Ran an end-to-end UX audit of the quote, policy-selection, and checkout flows and redesigned the complete user journey to lift conversion and revenue per visitor.
• Developed and implemented the tracking architecture (GTM + GA4 + server-side) for behavior insights, attribution, and ad-spend control.

Developing and evaluating the monetization strategy for a mobile B2C app and lifting the conversion performance of its integrated e-commerce shop.

Owning the CHECK24 Comparison App – 4 million monthly active users, natively developed for iOS and Android with separate development teams of four developers each – and all cross-vertical app matters, consumer-facing and internal. Core of the role: prioritizing feature requests from the verticals and the holding (stakeholder management across the CHECK24 verticals), growth, stability at that scale, and weekly releases coordinated across all vertical plugins.

• Designed and implemented the app as the central platform layer for CHECK24's business units and rolled it out across the group: a plugin architecture that let independent verticals integrate their own products, plus API-based shared services for authentication and customer accounts.
• Co-owned the release process of both apps, moving from three-week release cycles to a weekly release that shipped the app with all vertical plugins every Monday.
• Built and led the product team (2 PMs, 1 QA Manager, five working students) with full line-management responsibility.
• Reported directly to the founders and CEOs; main point of contact for C-level executives and directors of the verticals on all app-related topics.
• Developed standardized UX/UI design specifications to optimize conversion across CHECK24 products.
• Developed multi-channel marketing of CHECK24 apps and grew MAU from 400k to 4M within five years.

Setting up an automated process to collect and evaluate customer feedback for feature prioritization, and building the iOS and Android beta-tester community and the process behind it.
