I seek an experienced web developer to programmatically insert customized music player interfaces across several of my existing websites. The sites in question are built upon WordPress, NCH Broadwave, GoDaddy, and Webador platforms. As the site owner, I already have administrative login credentials and publishing capabilities established for each. The required task is to develop code snippets or widget solutions that can dynamically draw audio tracks from predetermined playlists that I control, and present an intuitive playback interface seamlessly integrated into the front-end design. Key functionality includes click-to-start streaming of selected songs or albums directly from embedded media players without disrupting the overall user experience of the sites. Skill with APIs or iFrames that enable automatic playlist updating from a centralized host would be preferable but not strictly necessary. A solid understanding of HTML, CSS, JavaScript and the website architectures involved is essential to complete this project efficiently and ensure cross-browser compatibility. Sample designs or prototypes are not needed, as the focus is on core functionality instead of graphical polish. Once installed, the players must be fully operational without requiring ongoing technical support. A high-level demonstration of similar work would help in the bidding and evaluation process.
