About

Engineer with a mathematician’s mind.

I’m Valeriia — a Full-Stack JavaScript developer originally from Dnipro, now based in Vienna. I hold a Master’s in Mathematics with honours and spent five years in business intelligence before moving into software.

I work across the stack — Next.js, React, Node.js, GraphQL — and care about clean code, considered interfaces, and products that actually mean something to the people using them.
