Hi there! I’m Andrey Kovlyagin, a full-stack developer based in Barcelona who started in graphic design and recently shifted to web development. I enjoy blending visually polished interfaces with solid, scalable backends, creating products that feel both delightful to use and reliable in production. I’m comfortable across the stack, with hands-on experience in React, Next.js, NestJS, and PostgreSQL. I thrive in collaborative settings, work well with product and design teams, and love turning ideas into practical, well-documented code. When I’m not coding, I’m thinking about typography, layout, and how to make interfaces easier to understand at a glance.
