Product development with a focus on user-centered design

With over 200 digital projects across large organizations, I have worked on consumer-facing apps as well as web apps for businesses with millions of users. This means I can quickly adapt and efficiently solve your product’s challenges through high-quality designs that leave your users satisfied.

Foundation

& Discovery

I lay the groundwork for success by gathering insights, defining hypotheses, and exploring creative ideas to improve the user journey.

In-Depth Research & Analysis
I use a variety of qualitative methods—such as user interviews, heuristic UX audits, stakeholder interviews, journey and persona mapping, and service blueprints.

Creative Ideation & Concept Development
Armed with a deep understanding of customer challenges and current solutions, i use ideation sessions—such as Workshops or Design Studios.

Focused Problem-Solving
with 'How Might We' Questions

Building on the product vision and strategic goals, i guide the team in crafting clear 'How might we' questions.

Prioritization & Concept Refinement

I use techniques like Dot Voting, the MoSCoW Matrix, and the Kano Model, to help methodically evaluate and prioritize ideas.

Rapid Prototyping

& Validation

I develop testable solutions for the selected idea. My goal is to quickly prototype and validate the concept, gaining clear insights into its value.

User-Centered Analysis & Alignment
Using the Value Proposition Canvas, i analyze the user’s perspective and map out the key features of the solution.

Defining Success Through Clear Metrics
To measure the success i can use key performance indicators (KPIs), objectives and key results (OKRs), and SMART goals.

Structuring the User Experience
UX methods like information architecture, user flows, and wireframing, help me creates the conceptual foundation.

Continuous Improvement

Whether it's a wireframe, prototype or MVP I develop by asking: How are current solutions used? Which offers the best improvements? And how can we optimize it further?

Testing

& Learning

I help you to challenge the status quo and transform your products into innovative industry pioneers.

Testing Method & Data Collection
I help to select the most effective research method and create a robust framework for collecting accurate, actionable data.

Diverse Testing Methods
for Actionable Feedback
I use a variety of testing methods—such as A/B tests, fake doors or user interviews—to gather valuable feedback from users.

Insight-Driven Reporting for Continuous Improvement

After testing, i report based on the results. This report serves as a foundation for the continued development of your solution in future sprints.
