I need a skilled full-stack developer to help improve the UI of an existing website for my US-based client. The goal is to make the interface more modern, clean, and user-friendly while keeping the experience smooth across all devices. The main focus will be on refining the frontend, improving responsiveness, and enhancing overall usability. You should also be comfortable making small backend adjustments if needed. Website: https://filelumo.com I’m looking for someone who has a good eye for design, understands user experience, and can suggest practical improvements instead of just following instructions. This will start as a short-term project, but there’s a strong chance of long-term work if everything goes well. If you’ve done similar work before, please share your portfolio or examples.
