About Tim

Hi, I'm Tim, a Lead Product Manager with 11+ years of experience building and scaling digital products across fintech, healthtech, e-commerce, and automotive sectors. I've led cross-functional teams at N26, Roche, Zalando, Siemens, and ThoughtWorks, consistently delivering high-impact outcomes — from 0→1 launches to growth and optimisation at scale.

I combine data-driven decision-making, strong product strategy, and deep user empathy to drive results. Whether it's scaling fintech platforms, driving digital transformation in healthcare, or shipping high-conversion experiences in e-commerce, I focus on outcomes over output.

💡 What I bring:

Product leadership from MVP to scale, with clear business results

Strong grounding in Agile, experimentation, and stakeholder alignment

Proven ability to turn ambiguity into clarity — and ship fast

I'm passionate about working with teams that value autonomy, craft, and velocity — and where product is a real lever for growth.
Let’s talk if you’re looking for someone who can own the problem, not just the backlog.

Experience

  • ThoughtWorks ESP
    Lead Product Manager
    August 2023 - August 2024 (1 year)
    Barcelona, Spain
    Siemens Financial Services (Fintech) (B2B)
    • Faced with an outdated and inefficient data framework, I led the creation of a Data Mesh programme within SFS.
    • I drove multiple financial accounting use cases from value proposition through to operating data product teams, prioritising the most impactful solutions.
    • Our approach resulted in a 50% reduction in unresolved tickets thanks to decentralised ownership, an 8% increase in uptime of critical data products due to improved monitoring and reliability, and a 15% boost in employee productivity from self-serve data access and higher-quality datasets.
    Zalando (Retail) (E-commerce) (B2C)
    • To address unreliable funnel metrics and support Zalando's North Star goal of increasing conversion revenue, I defined and delivered a suite of reliable checkout metrics based on user behaviour, payment and purchase options, device/platform, personalisation, segmentation, trust, and post-checkout feedback.
    • These insights led my team to launch features such as one-click checkout, express checkout, BNPL offerings, checkout recovery nudges, and device-level UX improvements.
    • Together, they drove a 25% increase in funnel revenue, equivalent to tens of millions of euros annually.
    • My role also included Agile product development, KPI tracking via GA, Tableau and Microstrategy, user research, A/B testing, and regular stakeholder alignment through Steerco sessions.

    Barcelona, Spain
    ROCHE (Health)(Pharmaceutical)
    • Roche needed a radical improvement to its data framework to adhere to its long term efficiency goals. I enabled the pharmaceutical client's adoption of Data Mesh through enablement workshops, stakeholder engagement, product vision alignment, and establishing success criteria.
    • I facilitated roadmap development and led the formation of new data product teams. This resulted in a 5% improvement in the data product release cycle and a 60% increase in time-to-insight by removing central IT bottlenecks.
    MOTABILITY (Automotive) (B2C)
    • Due to a lack of digital tools for its 600k customer base, I led Agile software team to build B2C "Digital Customer" products for automobile client, directly impacting all of its customers and resulting in adoption of certain features by 40%
    • In response to electric vehicle regulations, I also led the development of a procurement product ensuring 100% EV compliance across the fleet.
    • Daily responsibilities included conducting user interviews, prototyping with Figma, leading A/B tests, and refining product stories and roadmaps. I regularly presented progress at Steerco and All Hands meetings.
