    I support several enterprise customers running Avaya Experience Portal (AEP) with CTI applications that communicate through Avaya Aura Application Enablement Services (AES). To keep pace with their evolving requirements I need fresh code as well as updates to existing voice and desktop CTI components, all of which must slot cleanly into their wider CRM and reporting stacks. Scope of work New modules will handle intelligent call-routing logic, IVR customisation (prompt control, dynamic menus, backend look-ups) and detailed data reporting. Alongside that, some legacy Java and C# services require refactoring for stability and performance, and a set of JavaScript widgets must be wired into web-based agent desktops.

    Migrate Bubble.io Site to New Platform

    Varmennettu

    I built my entire website with but have now outgrown its limitations and would like to move everything to a more flexible, widely-supported platform. The live site is fully functional right now, so the job is a straight migration rather than a ground-up build. Here is what I need from you: replicate the current look, preserve every workflow, and make sure all data stays intact during the transfer. Once the new version is ready, I’ll point the domain to the fresh install and retire the Bubble instance, so a clean cut-over plan is essential. Backend logic, databases, and any third-party integrations already in place must keep working exactly as they do today; visitors should notice no disruption beyond the faster performance we’re aiming for.

Scope includes restoring full listing visibility, resolving server errors, repairing/optimizing cron jobs, and ensuring search filters (including “All Commercial Real Estate”) function correctly.

    I’m ready to commission a complete mobile app, delivered for both iOS and Android, whose core purpose is smooth, reliable music streaming 3 icecast streams. If we later decide to add mores streams or traditional songs, downloads, or playlist builders, I’d like the codebase to make that expansion straightforward. Account creation is optional. A guest should be able to open the app and start listening immediately, while a signed-in user unlocks conveniences such as playback history, favourites, and cross-device sync. Because of that, I need a lightweight auth flow (email, Apple ID, Google, or similar) that can be bypassed at first launch. Key points to cover • Native-feeling experience on both platforms—React Native, Flutter, or true native stacks are fine as long...
