Context

Stackup was an EdTech Chrome plugin and web dashboard that tracked students’ online reading and awarded classroom credit. The product helped teachers recognize reading that was already happening online, while motivating students through progress tracking, badges, challenges, and classroom competition.

I led the end-to-end UX/UI redesign of the platform, working closely with students, teachers, administrators, engineers, and business stakeholders to reimagine the proof of concept from the ground up. In addition to product design, I also handled frontend development and supported PPC marketing efforts to help drive user acquisition.

This work improved usability, increased engagement, and laid the foundation for long-term growth, ultimately contributing to Stackup’s acquisition by GG4L in 2021, when the platform was serving more than 10 million students.

The Problem

The original Stackup proof of concept had promise, but the product needed a more unified and effective experience to support growth.

Key challenges included:

  • An inconsistent experience across the Chrome plugin and web dashboard
  • Limited visibility into student reading habits and progress
  • Teacher workflows that needed to be clearer and easier to manage
  • Administrative reporting that could be difficult to interpret or act on
  • A need to motivate students in a way that felt engaging without undermining academic value
  • A product experience that needed to scale across classrooms, districts, and user types

This was not just a UI refresh. It was an opportunity to rethink how digital reading could be tracked, rewarded, and translated into meaningful educational outcomes.

My Role

I led UX/UI design from strategy through implementation.

My responsibilities included:

  • Leading end-to-end UX and UI design across the platform
  • Conducting user research with students, teachers, administrators, and business stakeholders
  • Facilitating kickoff planning, discovery, ideation, and prioritization workshops
  • Developing personas, flows, wireframes, prototypes, and high-fidelity designs
  • Building and maintaining the design system and frontend UI library
  • Completing frontend development for the website and Chrome app
  • Partnering closely with engineers during buildout, QA, and release
  • Supporting PPC marketing campaigns to help drive growth and adoption

Approach

1. Project Kickoff & Planning

To align the team early, I facilitated a structured kickoff session that gave us a shared understanding of goals, users, risks, scope, and success metrics.

This planning process included:

  • A kickoff canvas covering participants, goals, deliverables, milestones, and constraints
  • A Lean UX approach centered on rapid learning and iteration
  • An MVP target informed by user needs and business priorities
  • A measurement plan aligned to the Google HEART framework

Impact: Created shared alignment across stakeholders and gave the team a focused roadmap for research, design, and validation.

2. Empathize: Understanding the Users

I conducted research with both end users and business stakeholders to understand the product from multiple perspectives.

Discovery activities included:

  • Heuristic evaluation of the existing Chrome plugin and web app
  • Empathy interviews with teachers, administrators, and students through teacher facilitation
  • Firsthand classroom observation to understand actual reading behavior and context
  • Synthesis of research findings into themes, opportunities, and design priorities

Key insights included:

  • Students liked the idea of getting credit for online reading
  • Teachers wanted simple, goal-based tracking and visibility
  • Administrators needed reporting that did not require IT support
  • Parents wanted more confidence around privacy
  • Game mechanics like badges and challenges increased motivation

3. Define: Framing the Problem

After research, I translated findings into a clear product direction.

We defined the opportunity as follows:

We believed that if students could receive credit for all of their online reading, they would read more often, improve their skills, and explore their interests more deeply. We also believed teachers needed a fast and simple way to create goals and track progress in the classroom.

To sharpen our thinking, I used How Might We questions such as:

  • How might we track online reading so teachers can give students credit in the classroom?
  • How might we capture valuable data about online reading habits to help identify strengths and weaknesses?
  • How might we build a platform that encourages students to read and learn more?

Success metrics included:

  • Happiness, measured through satisfaction surveys
  • Engagement, measured through daily reading time and event tracking
  • Adoption, measured through user growth and new districts
  • Retention, measured through DAU/MAU

Impact: Established a clear product strategy that linked user needs, design decisions, and measurable outcomes.

4. Ideate: Exploring Possibilities

To generate and prioritize ideas, we used collaborative ideation methods and story mapping.

Activities included:

  • Collaborative sketching and whiteboard sessions
  • Crazy 8s exercises for key flows and experiences
  • User journey mapping to identify red routes
  • Story mapping to organize features into MVP and future releases

Key concepts explored included:

  • Reading challenges and badges
  • Role-based dashboards
  • Comprehension tracking and readability scoring
  • Parent-facing reports and Open Badges

Impact: Helped the team quickly explore multiple directions, prioritize the most valuable ideas, and focus development on the MVP.

5. Prototype: Bringing It to Life

I created annotated wireframes and interactive prototypes to bring the new experience into focus and gather feedback before development.

Work included:

  • Annotated wireframes for key workflows
  • Interactive prototypes in UXPin
  • Design exploration for student dashboards, challenge creation, and classroom leaderboards
  • Refinement based on stakeholder and user feedback

I also developed the foundation of the visual system:

  • A branded UI kit based on Bootstrap and a custom Photoshop design system
  • An HTML/CSS UI library to streamline developer handoff
  • Reusable components including buttons, badges, modals, and tooltips
  • Templates for both the product and marketing site

Impact: Created a consistent and scalable visual language that supported both product usability and faster implementation.

6. Test: Validating and Iterating

Testing was practical, collaborative, and closely tied to real classroom usage.

Testing activities included:

  • In-classroom usability sessions with students and teachers
  • Feedback forms embedded within the app
  • Sticky-note walkthroughs and affinity mapping
  • Ongoing measurement through HEART framework metrics, especially adoption and engagement

Key testing insights included:

  • The challenge creation flow was confusing for teachers, so I simplified steps and clarified labels
  • Students responded well to rewards, but badges were not visible or timely enough, so I improved visibility and delivery timing
  • Students wanted stronger progress visibility, which led to improvements in readability tracking and profile features

Impact: Improved the product’s usability and engagement by grounding decisions in real user behavior and continuous feedback.

7. Implement: Building the MVP

Once the designs were validated, I worked closely with engineering to bring the MVP to life.

Implementation work included:

  • Creating a responsive HTML/CSS/JS UI library using Bootstrap
  • Pairing with engineers throughout buildout and QA
  • Using BrowserStack to validate performance across browsers and devices
  • Supporting iterative releases and enhancement cycles after launch

I completed frontend development for the website and Chrome app, while full-stack and plugin developers handled backend and integration work.

We shipped the MVP in February 2016 and continued improving the product in two-week sprints after launch.
