About this service

Summary

I help businesses and startups create intuitive, visually appealing, and user-friendly digital experiences. Whether you need a brand-new design or a revamp of an existing product, I ensure that every detail is thoughtfully crafted to enhance usability and engagement.
I offer end-to-end design for mobile and web applications, combining strategic research, collaborative workshops, and the Jobs to Be Done methodology to create user-centered, high-impact products. My approach goes beyond aesthetics—I uncover real user needs, align stakeholders, and ensure the final product is both functional and business-driven. With a structured yet flexible process, I help teams turn ideas into intuitive, scalable digital experiences.

Process

Discovery & Research (Optional) If needed, I can help define your user needs, business goals, and product requirements through UX research, competitor analysis, and usability insights.
2. Sketches & Wireframes Low-fidelity wireframes to establish the layout, structure, and user flow before diving into the details. This ensures a solid foundation for your project.
3. High-Fidelity UI Designs Pixel-perfect, fully designed screens that align with your brand identity and are optimized for an excellent user experience. These will be ready for development, with all necessary design specs provided.
4. Interactive Prototypes Clickable, high-fidelity prototypes to demonstrate key user flows and interactions, helping stakeholders visualize the product before development.
5. Developer Handoff & Design System Components Well-structured design files, including design specs, UI components, and style guides to ensure a smooth handoff to developers.
6. Feedback & Revisions I offer iterations based on your feedback to refine the design and ensure it aligns perfectly with your vision.

Lisa took my chaotic app vision and turned it into something clear and beautiful. She built a full Figma system that brought it to life and made the process enjoyable. She's sharp, fast, and great at balancing structure with creativity.
