Migrated a legacy PHP codebase to PHP 8 and refactored it into an MVC architecture, reducing technical debt and easing onboarding for new developers. Containerized the local dev environment with Docker Compose, cutting new developer setup time from days to a few hours. Wrote Cypress end-to-end test suites covering key user flows, catching regressions before deployment. Wired Cypress tests into GitHub Actions CI, running automated regression tests on every pull request and blocking merges on failure. Built a full REST API for the platform, with Swagger documentation that auto-regenerates on each new endpoint, cutting manual doc upkeep. Developed and integrated the customer portal with Salesforce, syncing customer data in real time between the two systems for the support team. Designed and shipped a notification and PDF reporting module. Built an in-app notification system covering password resets, user assignments, and other key account events, keeping users informed in real time without manual follow-up. Designed a flexible reporting module letting admins configure custom report templates per customer standard, so end users could generate PDF reports in a few clicks instead of building them manually.
