Billboard Advertising Platform Developed a web application that allowed users to purchase billboard advertising spaces. Users could upload their ads, select their desired billboards, and make payments. The ads would be displayed at the chosen times. Service Marketplace Created a platform where people could offer products and services, which could be hired directly through the application. Uptime Monitoring Platform Built a platform to monitor uptime for any service using various protocols including HTTP, heartbeat, ping, and telnet. The platform offers customizable alert settings and provides real-time notifications on the status of monitored services. In each project, I led the development of both front-end and back-end components and managed version control using Git. I ensured the applications were fully responsive and implemented automated tests with every deployment to maintain functionality and reliability. Additionally, I oversaw server administration on AWS, configured CI/CD pipelines, and managed the entire infrastructure.
