MARI Platform Development for Water Wings Swim
Atarius Armstrong
Overview
MARI is an education management platform designed to give seamless progress management for instructional swim companies.
Problem
Water Wings Swim, a growing swim instruction company, was drowning in manual processes. The founder managed everything by hand—from scheduling to skill assessments—creating an unsustainable system that was time-consuming and error-prone. Instructors lacked an efficient way to record student progress or communicate with parents, resulting in reporting bottlenecks and inconsistent experiences.
Key Pain Points Identified:
Administrative tasks consumed excessive time that could be better spent teaching
No standardized method for tracking student skill progression
Limited visibility into class-wide performance trends
Inefficient parent communication regarding student progress
Paper-based processes vulnerable to loss and human error
Solution
I co-created MARI, a no-code learning management platform specifically designed for skill-based education. As the UX lead, I transformed manual workflows into an intuitive digital platform that now supports over 36 instructors and administrators.
Core Features Delivered:
Streamlined attendance tracking with bulk actions
Intuitive skill assessment interface
Automated progress reporting to parents
Class-wide performance visualization
Mobile-optimized interface for poolside use
Key Design Decisions
Redesign Student Roster as Vertical Cards
Why: Testing showed horizontal scrolling created confusion on mobile
Result: More intuitive navigation pattern aligned with mobile user experiences
Class Performance Visualization
Why: Instructors needed at-a-glance performance metrics
Result: Visual representation of skill averages allowed quick identification of class progress
Bulk Actions for Attendance
Why: Individual attendance marking was time-consuming in the limited window between classes
Result: Reduced attendance marking time by over 60%
Outcomes & Impact
✨ 36 users successfully onboarded across instructor and admin roles
✨ 80% of instructors reported confidence using MARI without additional support
✨ Progress report automation reduced hours of administrative time each week
✨ 85% task completion rate for core functions: submitting scores, taking attendance, and reading data summaries
“This makes it so much easier to see who’s falling behind. I don’t have to guess anymore.” — Instructor feedback
