Ø Working in AgileEnvironment, attended daily Scrums, backlog refinement meetings, Sprint planning every other week followed by Sprint retrospective meetings.

Ø Involved in gathering requirements from the product owners and performing Analysis, providing multiple Design solutions post analysis, developing solutions based on the designs, and Testing the end to end applications.

Ø Collaborated with developers from different teams to build multi-tier complex Enterprise Javacomponents and ecosystems to enhance the component reusability which reduces the work duplicity.

Ø Designing and implementing User Interface with high flexibility, efficiency and accessibility using HTML5, CSS3.

Ø Developing Single Page Applications (SPA) with least SLA times for the interface loads using Angular8, Typescript, Bootstrap and implemented catching mechanisms to achieve the same.

Ø Used various Angular 8 custom directives and developed reusable components and templates that can be re-used at various places in the application.

Ø Working on Angular Http services to make REST API service calls for data exchange from the SPA to the databases and aggregate the data of multiple service calls before sending back where required.
