Summary of I’ve been working in software development for 8 years, primarily on the .NET
Qualifications platform. I enjoy solving complex technical challenges, optimizing system
performance, and working with both modern and legacy codebases. I am a strong
team player, but I am also comfortable taking ownership and working
independently on projects.

I learn new technologies quickly and am not afraid to take responsibility for
complex tasks or unfamiliar domains. In recent years, I have also worked with AI-
powered solutions, including integrating LLM-based platforms, Azure AI services,
and building AI-assisted applications from scratch. I enjoy designing scalable
solutions, investigating difficult issues, and delivering reliable business value
through technology.
