ABOUT ME

Backend Developer with 1 year of practical experience building and
maintaining production web systems with ASP.NET Core. I specialize in
developing REST APIs, designing clean backend architecture, and
working with relational databases.
I developed and support a system used daily by real users for analytics
and data processing. I have experience across the backend development
lifecycle, from designing architecture and implementing new functionality
to deployment and ongoing support.
