About me

I graduated with a degree in Computer and Network Systems and started as an e-marketing manager. 3 years ago, I shifted to full-stack web development and completed a 12-month certification program.

Currently, I work as a Shopify Web Developer at Informatica, building performant, custom Shopify sites and improving business workflows. I also completed a React/Next.js internship at SoftRyzen and won first place at the Luxoft Hackathon for creating an accessible map of Kyiv.

My main tech stack includes React, Next.js, Node.js, and MongoDB, and I’m familiar with TypeScript. I love problem-solving and am always eager to learn new technologies. I’m looking for a full-time software developer role.

When I’m not coding, I enjoy reading, watching movies, playing basketball, and biking. I also love learning new things.
