In my professional experience, I have worked on the development and maintenance of two systems based on ASP.NET Core API, integrated with GraphQL. My main responsibilities included promptly implementing functional changes, enhancing architectural solutions, and introducing new features. Notably, I successfully integrated a payment system through a third-party service, which significantly expanded the application's functionality.I also actively contributed to the further development of the system, including the creation of complex reports using LINQ, which greatly improved data processing and report generation.My experience covers work with various technologies, including ASP.NET Core, PostgreSQL, GraphQL, HotChocolate, Docker, and Nginx. Additionally, I have worked with Kafka for stream data processing, which ensured a reliable and scalable architecture for handling messages and events.This experience has allowed me to deeply engage in the development of high-load systems, process optimization, and integration with external services, ensuring flexibility and scalability of applications.

Developed web applications in ASP.NET Core using C#, applying OOP principles. Implemented dependency injection for managing application components. Utilized Entity Framework and Fluent API for database operations, including creating stored procedures. Worked with large­scale MSSQL databases and executed queries involving multiple linked servers. Created REST APIs for data exchange with client applications and performed queries using LINQ. Developed internal applications using Angular and TypeScript. Additionally, collaborated with Cisco

I had experience with databases.Mostly I used ORM, but I also wrote in pure SQL.Most of the tasks were in ASP.NET, so there were tasks in JavaScript.Most of the tasks were in ASP.NET, so there were tasks in JavaScript.I created a rest api on Asp.net using asynchronous methods .I also added dependencies to services
