## The Problem

Brazilian Jiu Jitsu improvement is hard to measure. Unlike lifting weights, there's no obvious metric. "Did I get better this month?" is genuinely difficult to answer.

## What I Built

A comprehensive training platform for BJJ practitioners:
* Log training sessions and techniques
* Track what positions you're winning/losing
* Identify patterns in your game
* Set goals and measure progress

**Stack:** React, Node.js, MongoDB

## Key Learnings

**1. What gets measured gets improved**

Simply tracking which submissions I hit (and got caught in) revealed patterns I was blind to. Data creates awareness.

**2. BJJ is uniquely complex**

Thousands of techniques, positions, transitions. The data model had to be flexible enough to capture this without overwhelming users.

**3. Consistency beats intensity**

The app's most useful feature isn't fancy analytics: it's the simple training log that shows attendance over time. Showing up matters most.

**4. Community features require community**

Built social features, but a training app needs critical mass to be social. MVP should focus on personal tracking.
