Features like, service to service authentication, instance principal, on-behalf-of, delegation, federation, ephemeral credentials, swift authentication, and many more.* Breaking new grounds in authentication and authorization. Four patents for novel authorization artifacts management innovation.* Using Docker to build, manage, and deploy services. From July 2016 to March 2019 (2 years 9 months) Greater Seattle AreaFounder, Developer @ Yams • It is a simple social engineering app (Android for v1, iOS in later milestone) on the client side and a RESTful web service on the backend running on the cloud in Linux VMs. • The server is written in Python using Tornado for web framework and MongoDB to store the No-SQL data. From March 2014 to September 2015 (1 year 7 months) Redmond, WASoftware Development Engineer II @ Microsoft Working at the Windows Azure Runtime team. It's all REST-based APIs to perform any Azure management operation. Currently Azure uses mutual certificate authentication for these REST calls. Now this group wants to use claims-based access control (WIF rocks!) support and that is where I come in.SAML, REST, JWT, ADFS, AAD, Federation, trust, STS, OrgID, all coming to the picture.* First joined in the PaaS team. Worked on several of the PaaS APIs. Improved the claims-based access control logic* Currently working on the IaaS team. Added support for VM image repository support, caching images in different geo locations* Solved some race condition issues that happens in the IaaS pipeline. From September 2013 to November 2014 (1 year 3 months) Redmond, washingtonSoftware Engineer @ Caradigm I worked as a security expert for Amalga, now known as CIP (Caradigm Intelligence Platform), a health solution product (http://www.caradigm.com/pages/products/amalga.aspx). * Using claims-based access model from Windows Identity Foundation (WIF) and AD FS 2.0 as CIP's authentication/authorization story,* Designed and developed several back-end WCF services exposing public APIs.* These WCF services pull data from Microsoft SQL servers.* Exposing the data also through OData APIs.* Worked on moving the whole product to the cloud, i.e., Windows Azure. Developed stories how authentication will happen on the cloud for both our REST and SOAP based APIs. How multi-tenant/single-tenant will communicate to our cloud hosted CIP servers.* Developed a simple TFS client to keep track of individual/team work items as a side project.
