EduFusion - e-learning platform (UX research and product design)

Context & Problem

In spite of the rise of online learning platforms, completion rates of courses remain low. A study consisting of 18 students found that students were not completing courses because of behavioral, not instructional, problems. The problems include feelings of isolation, lack of career direction, overwhelming choices, and lack of accountability. The students enrolled with enthusiasm but failed to continue because of decision fatigue, motivation, and uncertainty.

Research

• Conducted qualitative interviews and behavioral analysis
• Synthesized insights using persona creation
• Identified three core barriers: lack of accountability, guidance gaps, and cognitive overload

Design strategy

Redescribed the platform as a content marketplace instead of a learning support system, with a focus on motivation and progression.

Solution

Instead of creating a passive content viewer, the aim was to create a supportive learning environment, and the main goals were to make learning easier to continue, boost motivation, and lessen isolation. Designed 40 screens for the following features

• Implement study groups for accountability
• Encourage motivation through collaborative learning
• Provide instant AI-assisted help and course recommendations
• Prioritize simplicity and ease of navigation

GadgetGo — gadget rental mobile application (end-to-end UX case study)

Origin

The idea is based on a real-life problem where one needs gadgets that are costly, but cannot afford them, so I thought of making a gadget-renting platform.

Research

Conducted a survey of 55 potential users, followed by 15 interviews with students, freelancers, and creators. 

Key insight: The main idea is that users want access, not ownership, but worry about complex rental systems and reliability.

Core pain points

• High cost of gadgets
• Brief need for gadgets
• Complicated gadget rental process
• Lack of trust in gadget conditions

Design process

• Built task flows for browsing, selecting, booking, picking up, and returning
• Designed intuitive filters, availability calendars, and transparent booking confirmations
• Information architecture that minimizes decision fatigue
• Prototyped mobile flows and conducted usability feedback iterations

Solution

A mobile-first rental system focused on clarity and trust

• Clear availability, visibility
• Guided booking process
• Support integration
• Simplified authentication and checkouts

• UX research: interviews, surveys, usability testing, task analysis, personas, journey mapping, heuristic evaluation
• UX design: information architecture, wireframing, interaction design, prototyping, accessibility
• Product thinking: problem framing, hypothesis creation, research synthesis, feature prioritization
• Tools: Figma, Miro, Jira, Adobe Photoshop, Canva, WordPress, Framer
• Research methods: qualitative and quantitative analysis, affinity mapping, competitive analysis
