ChessGrow
Chess training platform that helps players improve their skills through structured lessons, interactive exercises, and performance analytics.
Overview
ChessGrow is a chess training platform designed to help players improve their skills at any level. The system provides structured lessons, interactive exercises, and performance analytics. ChessGrow offers dedicated paths for different audiences: juniors (ages 4-9), children and adults (9+), and tools for schools and trainers.
Technical Details
Architecture
The platform is built on NestJS backend and Angular frontend. It follows Domain-Driven Design principles to model chess training concepts within the codebase.
Key Areas
Training System
- Structured lessons organized by age group, skill level, and topic
- Interactive exercises with immediate feedback and hints
- Progress tracking across different training areas
Game Analysis
- Import and storage of chess games in PGN format
- Move-by-move analysis with engine integration
- Identification of mistakes and missed opportunities
Analytics
- Performance metrics aggregated from training sessions and games
- Visualization of strengths and weaknesses
- Personalized recommendations based on player history
My Contributions
As a backend developer with frontend responsibilities, I worked on:
- Domain Models - Designed DDD-based entities and services representing chess training concepts such as lessons, exercises, user progress, and game analysis
- API Development - Created NestJS endpoints for training content management and user progress tracking
- Event Processing - Used RabbitMQ for asynchronous handling of game analysis requests and notifications
- Frontend Support - Contributed to Angular components for displaying training content and performance charts
Key Features
- Dedicated training paths for juniors, adults, and schools
- Structured training curriculum with progressive difficulty
- Interactive exercises with hints and explanations
- Game import and detailed analysis
- Performance tracking and analytics dashboard
- Tools for trainers to monitor student progress
Lessons Learned
Working on ChessGrow deepened my understanding of Domain-Driven Design in practice. I learned how to model complex domains like chess training into well-structured code, with clear boundaries between different parts of the system. The project also reinforced my experience with building scalable backend services and handling asynchronous processing patterns.
