// About me
Who I am
I'm an experienced software developer focused on .NET technologies and modern web development. I have years of practice designing and implementing web applications — from internal corporate information systems to public-facing websites.
Currently I'm intensively exploring the integration of AI tools into the development process, bridging classic enterprise development with the possibilities of large language models and services such as OpenAI, Anthropic and others.
Beyond development I have experience leading small teams, doing code reviews, building CI/CD pipelines and designing application architecture.
