Project 1: System for Cross-domain Identity Management Project Description

The System for Cross-domain Identity Management (SCIM) specification is designed to make managing user identities in cloud-based applications and services easier. The Specification suite seeks to build upon experience with existing schema and deployments, placing specific emphasis on simplicity of development and integration, while applying existing authentication, authorization, and privacy models. Its intent is to reduce the cost and complexity of user management operations by providing a common user schema and extension model, as well as binding documents to provide patterns for exchanging this schema using standard protocols. In essence: make it fast, cheap, and easy to move users in to, out of, and around the cloud. Responsibility

Example Group

Participated in the definitions of groups. Groups are used to model the organizational structure of provisioned resources.

Operations

Participated in developing the manipulation of resources. Developed the REST API with a rich but simple set of operations in SCIM. Those Rest API support everything from patching a specific attribute on a specific user to doing massive bulk updates by using Java.

Discovery

Developed three end points to discover supported features and specific attribute details to simplify interoperability.

Create/Get Request/Response

Participated in developing creation of HTTP POST requests and response. Participated in developing creation of responses by sending HTTP GET requests to the desired resource end point. It is developed by Java, Spring, JavaScript and React.

Filter Request/Response

Developed the Filter Request and Response. In addition to getting single Resource it is possible to fetch sets of Resources by querying the Resource end point without the ID of a specific Resource.

Code Test

Wrote Unit tests code for any feature I worked on and try to improve the test coverage wherever possible. Project 2: Security Token Service
