Back to original languageAbout Justine
✨ Product Designer UX/UI passionate, curious & empathetic
🔹 User-centric approach → I love involving tech, product, marketing, or business teams to co-create meaningful experiences.
🔹 Test & iterate → I believe in collective intelligence and the power of feedback to design useful, usable, and desirable digital products.
🔹 Data & analytics → Thanks to my background in Product Management, I analyze the impact of decisions to continuously optimize the user experience.
🔹 Custom optimized website design (no-code tools), I support freelancers and SMEs in showcasing their offerings and creating a clear path that facilitates conversion.
🎯 UX methods I use:
✔️ User Research (user interviews, surveys, card sorting, personas, mapping, tests)
✔️ Design Thinking (ideation, co-creation, UX workshops, design sprint, rapid prototyping)
✔️ Prototyping & Testing (low-fi, wireframes, Figma mockups, A/B testing, user testing)
✔️ Data-Driven UX (behavioral analysis, heatmaps, analytics, conversion funnel)
✔️ Design System (structure, scalability, tokens, UI components, Figma documentation)
💡 Experience:
3 years in a tech product startup + 1 year in a large company → a good balance between agility and scaled organization.
🎨 Tools & environments:
Figma (components, auto-layout, variants, tokens) · FigJam · Notion · Miro · Jira ·
→ Responsive design · Web App · Mobile Applications (iOS / Android) · Desktop · Multi-device · White label · B2C · B2B · SaaS
