About

I’m Justified Adesina, a product designer (UI/UX) with 4+ years of experience creating digital products people actually complete—across SaaS, healthcare, edtech, and Web3. I own projects end to end, from user research and flows to wireframes, testing, and high-fidelity design, while keeping timelines and client communication running smoothly.

I’m especially focused on turning messy ideas into cohesive product experiences through structured discovery, rapid iteration, and clear engineering handoff. Whether I’m building reusable design systems, stress-testing UX before development, or fixing retention problems by redesigning the real user journey, I move fast on remote teams and adapt to whichever toolset the problem needs.

The brief Wabbi Fluent was designed to make language learning more engaging, flexible and easier to maintain. Many learners struggle with consistency because lessons feel repetitive, progress is unclear, and daily practice can become overwhelming. The goal was to create a mobile learning experience that makes language practice feel simple, interactive and rewarding. What I did I explored user learning behaviors, identified common frustrations and mapped out key learning journeys. I designed a mobile experience centered on bite-sized lessons, interactive exercises and clear progress tracking. My work included user research, user flows, wireframes, UI design, high-fidelity prototyping and usability refinements. I focused on creating an intuitive interface that supports different learning habits while keeping users motivated. The outcome A modern language-learning app experience that makes daily practice feel more approachable and manageable. Wabbi Fluent brings together structured lessons, interactive speaking and listening exercises, and visual progress tracking to encourage consistent learning. The project reinforced my belief that great digital products don't just deliver features; they create experiences people want to return to.

The brief Prezence is an AI-powered personal branding platform designed to help young professionals build, manage and strengthen their online presence across multiple professional and social platforms. The challenge was to simplify complex AI-powered workflows into an intuitive, trustworthy experience that makes personal branding easier and more accessible. What I did I worked on the end-to-end UI/UX design, from understanding product requirements and mapping user journeys to creating wireframes and high-fidelity interfaces. I designed conversational AI onboarding, an intuitive dashboard, platform management, profile previews and content approval workflows. I also developed reusable UI components and responsive layouts for web and mobile, refining the experience through client feedback. The outcome A comprehensive UI/UX design for an AI-powered personal branding platform, featuring connected platform management, AI-assisted profile creation, content review and approval, and a scalable interface system. The final designs established a cohesive experience that gives users greater visibility, clarity and control over how they present themselves online.
