Converting an Excel Spreadsheet Into a Web Mobile-Responsive Application 100% Serverless, using Oracle Autonomous Database (Data Tier) and Oracle Application Express (App Tier) Integrated with OCI E-Mail Delivery Service in less than 2 hours.

In this project based on a real-world scenario, I acted as Cloud Architect to find a solution to the use of an Excel spreadsheet to control a Team Vacation Scheduling. To replace this spreadsheet, I designed and implemented an application using Oracle Application Express, Autonomous Database and OCI E-mail Service.

Below are few screenshots:
