Summary of
Qualifications I'm a .Net Software Engineer.

I have pretty decent 5 years of working experience on a few
enterprise .Net projects in various domains such as Trading,
Manufacturing and SSO projects. I constantly grow in technical
perspective and collaborative development. I am committed to
delivering qualitative, scalable, extensive, and responsive solutions
tailored to product complexity, while considering trade-offs and
leveraging the latest technologies.

Not only I can be valuable for hard skills but also I have good and
important skills of creating and leading the meetings, conducting demo
sessions, maintaining communication with client and the team
especially in English

AAA (authentication, authorization, accounting) server
Project Enterprise SSO solution for user authorization and user management.
Description:
Includes:

●​ Tools & Technologies: .Net 6, ASP.NET, Entity Framework (Code First), MS SQL
Server, GitHub
●​ Protocols: OAuth 2.0, Oidc
●​ Libraries: OpenIdDict
●​ Flows: Authorization Code flow with PKCE

Project Team 3 people
Size:
Responsibilities: Developing project from start​
Authorization server with generation of self-contained access token which supports
different kinds of flows for different clients (confidential and public ones). For public
clients it’s used Authorization Code flow with PKCE according to OAuth2.0 standards
to prevent clients tampering and ensure that data of the user can only be received by
authenticated apps.​
Each jwt-token contains different claims. The claims include scopes and basic user
information such as email, time the token was issued, expiration time etc. Having this
kind of information, different APIs can decrypt and validate tokens by themselves. The
most obvious benefit of this approach is that there is no need to store tokens and to
make additional requests to the Auth Server for token introspections.
