Every project starts with a real problem. Here's how we worked through four of them.

01Health & fitness2025

Sports Performance App

An app that helps athletes and coaches track training and see progress across a season.

The problem
Coaches tracked sessions in notebooks and group chats, so progress was hard to see and easy to lose.
What we built
A web app where athletes log sessions and coaches see each player's load, trends and goals on one dashboard.
The outcome
Coaches plan the week from real data, and athletes see their own progress at a glance.
