Fleezy IPTV Player Custom Build

I am looking for a developer to create a custom IPTV/media player application called Fleezy Player for Amazon Fire Stick, Fire TV, Android TV, Google TV, and similar Android-based TV devices. I am open to an existing IPTV player codebase, template, white-label solution, or previously developed application if it already works very well. The app does NOT need to be built completely from scratch. My priority is getting a stable, professional IPTV player that works properly on Fire Stick and Android TV, supports Xtream-compatible accounts, and can be customized with Fleezy Player branding. The finished application should be delivered as an APK that customers can install directly, including through the Downloader app on Fire Stick. BASIC USER FLOW Customer installs Fleezy Player → Opens the app → Enters Username + Password → App connects automatically to my internally configured Xtream-compatible server → Customer can access Live TV, Movies, Series, Guide, Favorites, Search, etc. The customer should NOT need to enter a server URL, portal URL, or playlist URL. The server URL should be configured internally by the app owner. IPTV / XTREAM COMPATIBILITY The app must support standard Xtream-compatible IPTV APIs. Compatibility with IPTV Boss XC Server is important. The application should support standard Xtream features such as: • Account login • Live TV categories • Live TV streams • Movie categories • Movies • Series categories • Series • Seasons and episodes • EPG / TV Guide data • Standard Xtream Live, Movie and Series stream URLs CUSTOMIZATION REQUIRED I need the existing player or codebase customized as Fleezy Player. Customization should include: • Fleezy Player app name • Custom logo • Custom application icon • Custom splash/loading screen • Fleezy colours and branding • Custom package/application ID • Branded login screen • Branded home screen • Branded menus/settings • Removal of previous developer/provider branding • Internal Xtream server configuration • Username + password login only I can provide branding assets if required. LIVE TV Live TV is the most important part of the application. Customers should be able to: • Browse Live TV categories • Browse channels • See channel names • See channel logos when available • See current program information • Add channels to Favorites • Search channels • Change channels quickly • Watch channels fullscreen The Live TV interface should be fast and easy to navigate using a Fire TV or Android TV remote. A TV-style layout with Categories → Channels → Program Information / Preview is preferred, but I am open to another design if the existing player already has a good TV interface. TV GUIDE / EPG The application should include a traditional television Guide / EPG. Ideally: • Channels displayed vertically • Time displayed horizontally • Programs displayed across the timeline • Current program information • Current-time indicator • Ability to select a program/channel directly from the Guide • Smooth D-pad navigation MOVIES The Movies section should ideally include: • Movie categories • Poster artwork • Search • Movie information • Play button • Favorites • Continue Watching / Resume if already supported SERIES The Series section should ideally include: • Series categories • Posters • Search • Series details • Seasons • Episodes • Episode playback • Favorites • Continue Watching if already supported FAVORITES AND SEARCH Customers should be able to save favorite content. Ideally this includes: • Live channels • Movies • Series Search should allow customers to quickly find content across the available library. PLAYBACK Reliable video playback is extremely important. The player should support common IPTV formats including: • MPEG-TS • HLS / M3U8 • H.264 / AVC • H.265 / HEVC where supported by the device • Common IPTV audio formats If the existing player already supports these features, I would also like: • Audio track selection • Subtitle selection • Aspect ratio options • Stream information • Resolution information • FPS information • Buffer options These advanced features are useful, but reliable playback is more important. FIRE STICK / ANDROID TV REMOTE SUPPORT The entire application must work properly with a standard TV remote. Customers should be able to navigate using: • Up • Down • Left • Right • OK / Center • Back I do not want an application that requires a touchscreen, mouse, or air mouse. The selected item/focus should always be clearly visible. The interface should feel like a television application, not a phone app stretched onto a television. PERFORMANCE The app may need to handle large IPTV catalogues. This can include: • Thousands of Live TV channels • Large Movie libraries • Large Series libraries The application should remain responsive with large accounts. If necessary, the developer can use: • Local caching • Database storage • Lazy loading • Category-based loading • Background syncing • Pagination • Other performance optimizations Live TV should ideally become available quickly after login instead of forcing the customer to wait for the entire Movies and Series catalogue to load. HOME SCREEN I would like a clean, modern TV-style home screen. Possible sections include: • Live TV • Guide • Favorites • Movies • Series • Search • Recently Watched • Continue Watching • Settings The exact design can depend on the existing player being customized. DESIGN STYLE The design should be: • Dark • Modern • Clean • Professional • Easy to read on a television • Fast and simple to navigate I am not expecting a completely unique UI if an existing high-quality player is being customized. I care more about reliability, usability and performance than whether every screen was designed from scratch. APK / DISTRIBUTION The finished app must be delivered as an APK. It should install and work on: • Amazon Fire Stick • Amazon Fire TV • Android TV • Google TV • Android-based TV boxes Customers should be able to install it through Downloader using a direct APK lin
