Yuliia

Full stack engineer with a backend focus. I build scalable backends, APIs and secure authentication, and the web and mobile apps on top.

Work

Four years building production systems that need to stay up and stay secure. Right now I'm also building my own iOS apps.

I can help with backend systems and APIs, cloud infrastructure on AWS, authentication and access control, AI agent integrations, and web and mobile apps.
