- Developed backend APIs using PHP and RPC, specifically gRPC. This involved defining service methods and their request and response message types using protocol buffers, and implementing these methods in a PHP backend server- Created a user interface using React.js, which involved setting up a React application and defining the structure of the application's components- Integrated the APIs with the UI by writing scripts that allowed the React application to communicate with the PHP backend server. This involved using the gRPC-Web API to write a simple client for the service- Wrote scripts for automation testing and cron jobs, which involved setting up a testing environment and writing scripts to automate certain tasks- Edited and Added Some Docker scripts and deployment scripts for the application. This involved setting up a Docker image for the application and writing scripts to deploy the application on a server.- Made improvements to the database and enhanced the performance of the APIs. This involved optimizing database queries and implementing performance-enhancing features in the APIs

Transitioned from working with PHP APIs to developing applications in Node.js. This involved migrating existing APIs to Node.js and integrating them with the user interfaceImplemented report export functionality in various formats such as CSV, XLSX, and JSON.Uploaded these reports to Google Cloud Storage (GCS) Created REST APIs with Node.js and Express, installed necessary dependencies, created routes, and handled different types of HTTP requestsIntegrated these APIs with various analytics tools to monitor their performance

Developed user interfaces utilizing React, transforming HTML-based templates into their React counterpartsIntegrated applications with backend APIs, facilitating data exchange and enhancing application functionality Integrated APIs with Payment SDKs to enable seamless online transactions Optimized web performance through techniques such as page splitting, resource cutting, and server-side rendering Conducted website testing using tools like Lighthouse and GTMatrix, ensuring optimal user experience and performance and able to improve performance to 98% overall score on Lighthouse.
