Enterprise LMS platform
[Development · e-Learning for life]
Learning platform built with TDD and CQRS. Led development of a complete LMS platform (content, assessments, certifications) rigorously applying Software Engineering patterns (TDD, CQRS, SOLID). Scalable architecture with Phalcon PHP and Vue.js to support Flipped Learning methodology and ensure enterprise-quality code for the long term.
Results
- Minimal[Result]Technical debt (TDD + SOLID)
- CQRS[Result]Sustainable scalability
The problem
Develop an enterprise-quality LMS platform that supports educational multimodality (Flipped Learning, varied multimedia content), ensures critical data integrity (traceable assessments and certifications), and long-term maintainability with clean architecture for constantly evolving educational requirements.
The solution
As Software Developer Lead, I established architecture and development standards ensuring impeccable, maintainable code. Rigorously applied TDD for reliability, CQRS to optimize read/write performance, and SOLID principles for a modular and extensible system. Developed critical modules: content management, virtual classroom, assessments, and certifications.
The challenge
Creating an enterprise-quality educational platform
- Educational multimodality
- Support courses with Flipped Learning methodology and manage varied multimedia content.
- Data integrity
- Ensure that assessments and certifications were traceable and accurate (critical for academic integrity).
- Long-term maintainability
- The system required clean architecture and disciplined code to support the constant evolution of educational requirements.
The approach
Rigor and advanced patterns
- Software engineering patterns
- I led the development rigorously applying advanced design patterns, including TDD (Test-Driven Development) to ensure code reliability and CQRS (Command Query Responsibility Segregation) to optimize database read/write performance and scalability.
- Design principles
- I implemented SOLID principles and other patterns to ensure the system was modular, extensible, and loosely coupled.
- Critical functionality
- I developed key modules such as academic content management, virtual classroom, assessment control, and certification modules, all built on a high-performance stack (Phalcon PHP and Vue.js).
The impact
The impact and evidence of discipline
- Code quality and maintainability
- TDD and SOLID standards resulted in a platform with minimal technical debt and high resilience, facilitating platform evolution over subsequent years.
- Sustainable scalability
- Using patterns like CQRS ensured the platform could scale and handle user growth and multimedia content complexity without compromising performance.
- Complex content management
- The modular design effectively supported the Flipped Learning methodology, enabling integrated management of content, assessments, and certifications.
