Worked on shapeblue/cloudstack to enhance both user interface clarity and backend data integrity within a one-month period. Developed a new feature in the System Offerings UI using Vue.js and JavaScript, adding a column that clearly displays High Availability status for each offering, which improves customer visibility into system capabilities. On the backend, strengthened API validation by making the account UUID a required parameter for offering creation commands, using Java to ensure only complete and valid requests are processed. This combination of frontend and backend improvements addressed operational risks and contributed to more reliable and transparent cloud management workflows.
