Freelancer profile translated to English.

Description

With several years of experience in development, I am a .NET Lead Developer expert in designing and implementing high-performance backend solutions, particularly with C#, ASP.NET Core, and EF Core.

I also master Microsoft technologies for the frontend, such as WPF and Razor, as well as modern frameworks like Angular and Vue.js.

Interested in DevOps practices, I also integrate tools like Jira, Bitbucket, and Git to optimize development and deployment processes.

My goal is to combine technological innovation and operational efficiency while mentoring teams to deliver solutions tailored to business needs.
