About

Shopify-focused Frontend & Full Stack Developer with hands-on experience in building, optimizing, and troubleshooting e-commerce stores. I work with Liquid, HTML, CSS, and JavaScript to implement custom features, improve user experience, and ensure smooth store performance.

I’ve worked on real Shopify stores where I focused on UX/UI improvements, product organization, and conversion optimization, as well as solving layout and functionality issues directly in code. I’m comfortable understanding existing codebases, identifying problems, and implementing clean, scalable solutions.

In addition, I have full-stack experience with React, Node.js, and MongoDB, building applications with authentication, API integration, and structured frontend logic.

I’m proactive, detail-oriented, and easy to work with. I value clear communication and always aim to deliver reliable solutions that not only work, but also improve the overall experience for users and teams.
