Summary I have commercial experience with Shopify Remix Hydrogen, as well as both public and
custom Shopify apps. I'm currently deepening my skills in Liquid and exploring advanced
Shopify theme development.

My background is in full-stack development with JavaScript, HTML, CSS, and React. I enjoy
tackling complex, multistep tasks and adapting to new challenges. I’ve even won a hackathon
as part of a team.

At the same time, I value delivering real results — like launching my own Hydrogen store and
building apps that solve real business problems.
