Continuously maintaining and extending a PHP-based application that serves as the core of the digital ecosystem, powering the marketing site, admin dashboard, proprietary CMS, e-commerce platform, and LMS. Enhanced the system by integrating Vue.js applications and managing the MVC architecture, libraries, and REST API, ensuring a cohesive framework for development and integration across the platform.

This monorepo serves as the backbone of the entire digital ecosystem, powering everything from e-commerce and content management to LMS delivery and administrative tooling. As the longest-running project I contributed to, it required working across a sprawling PHP codebase spanning CodeIgniter 3, Symfony 6, and Moodle while coordinating changes that rippled across the platform.

My contributions touched nearly every domain in the system. On the e-commerce side, I built eBook refund eligibility logic, transaction lookup pages, and Braintree payment error handling. Within the LMS, I helped develop the base course copy feature, a multi-month initiative enabling bulk assignment copying with due date retention, gradebook ordering, and parent course support. I maintained the cloze question engine, adding financial formula support for PV, PMT, and SQRT functions along with formula evaluation scoping and percentage formatting. I also built the OfficeJS integration layer enabling communication between the platform and Excel add-ins through postMessage-based event handling.

The technical breadth extended to Freshdesk API ticket management, Pipedrive CRM integration, academic email validation, Redis caching with serialization improvements, Docker configuration, and ECS scaling for production infrastructure. I replaced a legacy academic email validation library with a custom school list lookup, performed a comprehensive Moodle accessibility audit, and contributed to the ongoing Symfony DDD migration within the legacy codebase.

This project represents sustained, high-impact contributions across a complex backend system, demonstrating the ability to operate effectively across multiple frameworks, domains, and layers of infrastructure.
