At Virgin Plus, I worked as a web developer focusing mainly on front-end development. I fixed bugs in a large JavaScript codebase that manipulated the DOM with jQuery, ensured accessibility compliance following W3C Accessibility Guidelines, and adapted features for mobile browsers. I migrated the front-end from Angular to React, collaborating with team members to develop an API for React and Java backend integration. Additionally, I participated in a complex migration to Google Cloud by containerizing applications with Docker, setting up nginx servers, implementing load balancers, and re-writing legacy software to adapt to the cloud environment.

At Virgin Plus, I was primarily responsible for front-end development using FreeMarker (Java-based template engine), fixing bugs in a large JavaScript codebase, ensuring accessibility compliance, migrating the front-end from Angular to React, and collaborating to create APIs for backend communication. Additionally, I participated in a team project to migrate the system to Google Cloud Platform, utilizing Docker containers, nginx, firewall rules, and load balancers while adapting software to run efficiently in the cloud environment.

Front-end development and migration work: migrated the front-end from Angular to React, fixed a 5,000+ line legacy JavaScript/jQuery codebase, implemented input validation improvements (including regex for phone numbers), and addressed mobile layout issues to preserve accessibility. Improved screen-reader accessibility and aligned the front-end with W3C guidelines. Collaborated with back-end team to create an API enabling React to communicate with the Java back-end. Led a Google Cloud migration including Docker containerization, nginx configuration, and setting up load balancer and firewall rules to route traffic securely.
