Project Information
Client Name : Appvestor ApS
Date : Jun. 2023 - Jan. 2025
Location : Copenhagen (On-Site)
Project Beginning
When I joined Appvestor in 2023, the company’s new publisher platform was in a phase of rapid growth. While functionally powerful, it had been developed quickly to meet tight deadlines, resulting in a UI that lacked a cohesive design system and reusable components.
The Challenge
As the platform scaled, the absence of a unified design system created significant challenges. It led to inconsistencies in the user experience, slowed down development cycles, and made it difficult to maintain a high standard of quality. My primary challenge was to address this “design debt” by creating a robust and scalable solution.
Challenge on this Project
- Driving Adoption of the New Design System
- Balancing New Feature Development with Fixing Design Debt
- Designing a Data-Rich Interface for a Technical Audience
- Creating a Cohesive UX Across a Fragmented Platform
My Role & Contributions
As a UX/UI Designer and Product Designer, my mission was to bring consistency, efficiency, and a user-centric focus to the platform. I acted as a bridge between design, product, and engineering, ensuring that we built solutions that were not only beautiful but also intuitive and valuable for our users.
My key responsibilities and contributions included:
- • Building a New Design System from Scratch I led the initiative to create a comprehensive design library in Figma. This involved auditing all existing components, defining a consistent visual language (typography, colors, spacing), and building a library of reusable, scalable components. This new system is now the single source of truth for all design and development.
- • Improving and Redesigning Key Features I was responsible for the end-to-end design process for new features. This included translating complex requirements into simple user flows, creating low-fidelity wireframes for rapid validation, and delivering polished, high-fidelity UI designs that enhanced user engagement.
- • Fostering Cross-Functional Collaboration A core part of my role was ensuring seamless collaboration. I worked closely with developers to ensure pixel-perfect implementation, and with Product Owners, Product Managers, and management stakeholders to align on strategic goals and user needs. My focus was always on finding the most effective solution that balanced user value with technical feasibility.
- • Enhancing the User Experience Ultimately, my work was about solving problems for our users. By standardizing the interface and improving usability, we created a more intuitive and professional platform, leading to a more positive and engaging experience for app publishers.
