02 / APPROACH

Across the stack, focused on the user.

I’m a full-stack developer who enjoys the point where product thinking meets implementation.

My work spans responsive interfaces, application state, APIs, authentication, data modeling, and deployment. I’m most useful when a product has several moving parts that need to feel simple to the person using it.

I hold a bachelor’s degree in Computer Science from the International Science and Technology University in Kyiv, Ukraine, and continue to deepen my practice through independent product work.
