Next.js Developer needed for Website Improvements & Refactoring

I am looking for an experienced Next.js / React developer to upgrade and improve my existing website. The core codebase is already built, but it needs technical adjustments, optimization, and feature updates. To save your time, I am not writing a long description here. If your experience fits, I will share the project details and repository with you directly. Requirements: - Strong expertise in Next.js and React.js - Clean and structured code style (code review will be required) - Good communication and responsibility. Please include a link to your GitHub / GitLab profile or specific repositories when applying.
