Playfácil is an LMS (Learning Management System) designed to deliver engaging training content in a "Netflix-style" experience. Thousands of users rely on Playfácil to complete courses and track their learning progress.

The platform had major issues affecting user experience and training effectiveness. Course completions were not properly recorded in reports, causing confusion and compliance risks. Other flaws, like progress tracking errors and unrestricted course editing, further disrupted administrators and learners. Fixing these problems was essential to maintaining Playfácil’s reliability.

To tackle these problems, I started with a full technical assessment, mapping out infrastructure and code weaknesses and identifying key areas for improvement.

My contributions included:

Refactored report logic to summarize users' course completions correctly, eliminating a long-standing issue since the platform's first release

Fixed progress tracking bugs, ensuring visual elements like progress bars accurately reflected learning completion

Implemented course edit restrictions, preventing modifications to courses already in progress to maintain content integrity

Optimized database queries for better performance and faster report generation

System reliability proposed infrastructure improvements in AWS, Docker, and PostgreSQL

Language & Framework: PHP, Laravel, Blade

Cloud & Infra: PostgreSQL, Docker, AWS (EC2)
