Our goal is to empower traders and investors of all experience levels with smart analytics, personalized portfolios, staking, and seamless exchange features - helping them make confident financial decisions.

The Problem
The world of cryptocurrency trading remains overly complex and intimidating for many users, especially beginners.Existing platforms often overwhelm users with technical jargon and cluttered interfaces - leading to poor decision-making and a steep learning curve.
User Personas, Their Googles & Needs
User Flow

Messaging During Playback
Users can ask questions during playback by tapping a subtle icon. This opens a chat-like input, where the instructor (or an AI guide) can respond later. It keeps the learning/conversation flowing without breaking immersion - a major differentiator from static video platforms.
Accessibility
The platform supports:
Multiple caption sizes and spacing presets (Compact, Large, Low Vision)
Thumb-friendly layout for core controls (play, rewind, message, subtitles)
Quick toggles for speed and quality (available via intuitive overlay on tap)
Clear text hierarchy and scalable UI elements
Partially optimised for one-hand use
Screen reader-friendly designed for minimal cognitive load

Video Player for Learing and Storytelling

Prototyping
In an age where attention spans are short and video is the dominant medium, we built a gamified mobile video player that transforms passive watching into interactive learning.
Originally designed for education, the platform evolved into a universal, creator-first storytelling player where users engage
through quizzes, chat, and accessible controls.


Studies show active recall improves retention by 70% vs. passive watching
The Problem
We’re living in a clip-thinking era - people consume information fast, in bursts, and primarily through video. But video players haven't evolved much: they're linear, passive, and offer no meaningful way to engage or measure understanding.
Creators - from educators to storytellers - needed a tool that keeps users engaged, gives feedback, allows for interaction, and makes even 2-minute clips feel meaningful.
I led UX for this transformation - from niche tool to scalable learning infrastructure - resulting in 40% higher completion and strong user retention.
Accessibility
To turn passive video consumption into active engagement, we implemented timed, context-aware quizzes directly within the video experience. Rather than pulling users out of the flow, these interactions appear naturally at key moments - reinforcing comprehension and prompting reflection without feeling disruptive.
