I contribute to website performance metrics by optimizing scores, page load times, and code reusability. This involves contributing to the development of the architecture, implementing the front-end, designing middleware and service layers, providing guidance and mentorship to the team, and crafting a comprehensive test plan with test cases for development, testing, reporting, and post-deployment analysis to evaluate performance.

I undertook a comprehensive transformation project by converting the existing monolithic client corePHP application into a service-based architecture, employing Node.js, Angular 4, and Spring Boot. This overhaul also involved a database restructure, transitioning from a pure SQL setup to a hybrid SQL + Mongo configuration to enhance HTTP request handling and expedite reporting processes.As part of this initiative, I created a robust Node.js backend, complete with an Express web server. To bolster security and access control for client users, I devised a custom credential and permissions system, leveraging RouteGuards and Interceptors.Moreover, I took charge of designing and constructing administrative dashboards that offer real-time insights into refill statistics and trends. For effective data visualization, I utilized RxJS and ChartJS.Lastly, I managed the deployment and application infrastructure, ensuring the seamless operation of the production application on Google Cloud Platform (GCP).

I developed more than 10 user-friendly web applications using CakePHP 2.0 and core PHP. I was responsible for designing and implementing the data model using MySQL for these websites. Additionally, I utilized jQuery to improve the frontend by adding interactive features, including client-side validation.
