Senior UI/UX developer

We are building a custom AI model marketplace where users can discover, purchase, and access AI models through a modern, scalable platform. Our core product logic has already been implemented by a team of four developers, and we are now looking for a Senior Frontend Developer to continue and complete the existing work. One of our frontend developers had to step away due to personal circumstances, so we need an experienced developer who can quickly understand the current codebase and take ownership of the remaining frontend development. A key priority is completing and refining the mobile product UI, which is not yet finished. You will work closely with our existing development team to ensure consistency between the current implementation and the remaining features. The ideal candidate should have strong experience with React, Node.js, SASS, Tailwind CSS, responsive design, and modern frontend development practices. Strong UI/UX skills are highly preferred, especially experience creating clean, intuitive, and responsive interfaces for both desktop and mobile platforms. You should be comfortable reviewing existing code, identifying unfinished areas, improving components, and implementing production-ready solutions. Attention to detail, strong problem-solving ability, and a high standard for UI quality are essential for this role. Since this is an active project, we are looking for someone who can start quickly and make meaningful progress from the beginning. This position has the potential to become a long-term collaboration as we continue expanding the platform and adding new features. If you are confident in your frontend and UI/UX abilities and can take ownership of this project, we would be happy to discuss the opportunity with you.
