Overview
SmartGoal is an athlete performance and goal-tracking platform that brings data-driven training to recreational athletes. The platform provides analytics dashboards, progress tracking, and actionable insights to help athletes improve systematically.
Built for athletes who want to train smarter, not just harder — without needing a sports science degree.
My Role
As lead software engineer and project manager, I created SmartGoal end-to-end solo:
- UX Design — Created intuitive interfaces for complex performance data
- Full-Stack Development — Built the complete Node.js/React application
- Data Visualization — Designed and implemented analytics dashboards
- Algorithm Development — Created goal-setting and progress algorithms
- Database Design — Structured MySQL for efficient time-series queries
Built entirely by me.
Architecture
Analytics-focused architecture built for performance data:
Backend
Node.js with Express. MySQL for structured workout data. Optimized queries for time-series analysis.
Analytics Engine
Aggregation pipelines for performance metrics. Trend detection algorithms. Comparative analysis against goals.
Visualization Layer
React with Chart.js for interactive charts. Responsive dashboards for mobile and desktop. Export capabilities for training logs.
Data Model
Workouts contain exercises, sets, and metrics. Goals linked to specific metrics with targets. Progress snapshots for historical comparison.
Hard Problems
1. Metric Variety
Different sports have different KPIs. Designed flexible metric system that adapts to any sport or activity type.
2. Progress Visualization
Athletes want to see improvement clearly. Created multi-dimensional progress views that show trends across different time windows.
3. Goal Recommendations
Setting realistic goals requires context. Built recommendation engine based on historical data and improvement rates.
4. Data Entry Friction
Athletes won't log if it's tedious. Optimized input flows with smart defaults, templates, and quick-entry modes.
What I'd Improve Today
- Integrate with wearables and fitness trackers for automatic data capture
- Add AI-powered training recommendations
- Implement social features for team training
- Create coach dashboard for managing multiple athletes
- Add video analysis for form improvement
- Build predictive models for injury prevention
