EXPERIENCE:

SOFTWARE DEVELOPER

Confidential, MCLEAN, VIRGINIA

Responsibilities:

• Was the main developer of XMPP chat with Openfire and ejabberd backend servers integrated into Confidential Incident Management System (IMS) web application.
• Worked on transforming monolithic IMS ASP.NET web application into a single-page front-ends and the set of WebAPI web services protected by OAuth 2.0.
• Confidential in securing web applications, removing sensitive data from being passed through URLs, proper authentication and authorization of .NET pages.
• Replaced timer-based IMS notifications with instant push notifications using SignalR technology.
• Implemented SAML-based Single sign-on functionality for IMS, allowing users of selected Confidential clients to automatically log into IMS (Service Provider / SP) with their identity.
• Designed and developed NodaTime-based DateTimeZone library and web service allowing to determine full zone information, including Offset, DST, full Zone name, etc. based on a local time and latitude / longitude coordinates.
• Developed various new features of Incident Manager application using AngularJs framework.
• Participated in obtaining FedRAMP turning our application into JARVISS (Joint Analytic Real-Time Virtual Information Sharing System) used by US Army and Navy.

Environment: C#, ASP.NET, SignalR, SQL, JavaScript, AngularJs, NodeJs, HTML, Json, XML, XMPP. SQL Server, .NET libraries, Jasper and Telerik Reports, TelerOpenfire and ejabberd XMPP servers, Bing and HERE maps, legacy applications. VS 2019, IIS, TFS, GitHub, Jenkins.

SOFTWARE ENGINEER

Confidential, FAIRFAX, VIRGINIA

Responsibilities:

• Confidential in designing new modules, enhancement of database structure, and developing of dynamic client-side interface using Ajax.
• Conducted a technology research and developed well-structured, N-Tier, domain-driven application design. Was steadily applying modern functional techniques (extension methods, lambda expressions, LINQ.)
• Developed a technique for a secure data exchange between ASP.NET and legacy ASP pages. Worked on a custom single sign-on module for CoTs Intranet.
• In maintaining a legacy codebase, introduced more structured approach of reusable functions located in ASP include files.
• As the single most important, designed from scratch and developed custom permission system for CoTs Intranet. The complex and highly granular permission logic of CoTs Intranet was initially hard-coded into ASP pages, making it unmanageable. Over a year of research and development I created a new system called Roles and Rights Management System (RRM), database-driven and based on fundamental notions of a Role, a Right (permission), and a Scope. It included an administrative interface and made it easy to maintain CoTs Intranet permissions. I was given Employee Of The Quarter for creating the system.

Environment: C#, ASP.NET, VBScript, ASP, SQL, JavaScript, HTML. SQL Server, MS Access, custom .NET libraries. VS 2012, IIS, TFS.
