Hi, I‘m Melissa, a product designer based in Porto.
I take a holistic approach to designing user-friendly solutions that make sense for both users and companies. From research and wireframes to prototypes, design systems, and polished interfaces, I love teaming up with product, marketing, and engineering to bring ideas to life!
Selected case studies
FINOA
Partnering closely with product and engineering, I led a full redesign that created an intuitive, trustworthy experience, growing users from 300 to 700, tripling frequent users, and raising Net Promoter Score (NPS) from 78% to 99%.
KNOK
At Knok, I worked on core tools, including an AI-powered Symptom Checker, Remote Vital Signs Reader, and Nurses Triage Platform, to strengthen the telemedicine experience, and support over 1.2M patients across multiple countries.
JUMIA
Jumia, the leading African e-commerce platform, faced fragmented experiences across mobile and web, slowing purchases and frustrating users. I contributed to the redesign of the web and mobile apps, creating a mobile-first, intuitive, and scalable platform that simplified shopping, built trust, and empowered millions of customers across Africa.
7EGEND
At 7EGEND, I designed digital experiences that blended brand identity with usability across hospitality, entertainment, and e-commerce. From apps for McDonald’s and multi-brand retail platforms to festival guides, I created intuitive, engaging, and cohesive interfaces that delighted users and strengthened brand connections.
