    My Copilot agent publishes without any errors or delay warnings, yet none of our users can see it inside either Copilot or Microsoft Teams. Because the problem affects every user, I’m confident this is a configuration or deployment gap rather than an individual-profile issue. I have already: • Re-deployed the agent several times. • Verified user and app permissions in Teams and the Microsoft 365 admin center. • Read through Microsoft’s support documentation and known-issue articles. Even after these steps, the agent still refuses to surface. I worked through part of the Copilot Studio configuration wizard, but I’m not convinced every setting (particularly channel enablement, security roles, and app manifest details) is correct.

    I have an idea I’m ready to turn into a concrete project, but I need a professional’s insight to refine the scope, choose the right technology stack, and map out an actionable plan. I’m open to different approaches—whether that ends up involving web development, a mobile app, or a completely different digital solution—so long as it aligns with the business goals we uncover together. Here’s what I’d like from you: • A brief discovery call or chat to understand my objectives and constraints. • A written outline summarizing recommended features, milestones, and an estimated timeline. • Clear next-step suggestions (including any design, development, or integration considerations) so I can move forward with confidence. If you ...

    I’m ready to release the first cut of my cross-platform fitness application and need it built in Flutter so it ships simultaneously to iOS and Android. The scope is intentionally lean: just the essentials that prove the core experience works while leaving room to layer on advanced capabilities later. Core flow • Secure email-and-password signup and login wired to Firebase Authentication. • A workout video library screen fed from a simple Firestore collection (no complex categorisation yet). • A personal profile where users can: – set fitness goals, – track workout history, – and update their basic information. • Clean, maintainable Flutter code with state handled predictably (Provider, Riverpod or Bloc – I’m open ...

    I’m ready to launch a fresh Android-only marketplace where users can trade both physical and digital items from a single, intuitive mobile experience. The core of the first release is solid user profiles that let sellers manage listings and buyers track favourite items, messages, and purchase history. Here’s the flow I have in mind: a new user signs up, creates a profile, and can immediately post an item with photos (or upload a digital file), set a price, and choose basic shipping or direct download. Other users browse, filter by category or keyword, open the seller’s profile for credibility, and then move forward with the transaction. For now, payment handling will be kept minimal; we can discuss whether to start with a simple cash-on-delivery or voucher code approac...

    I have three fully-built Android apps( productivity tools ) that are code-complete and run exactly as intended, so no additional bug fixes, new features, or UI changes are required. What I need now is an experienced Google Play Console publisher to guide each app through the final submission steps and get them live on the store. The project is finished once the apps are approved and visible in the Google Play Store. Let me know your turnaround time and any additional details you’ll need from me (Having an active play console is an advantage and youll be hired immediately)

    I need a focused Android mobile application that reliably captures and stores device location data. The core scope is limited to two key capabilities: • Real-time location tracking that updates smoothly in the foreground and, where possible, in background mode without draining the battery. • A searchable, timestamped location history that is saved locally and can be exported in a common format (CSV or JSON). I am not requesting geofencing at this stage, but the code structure should make it easy to bolt that on later. Feel free to use Google Maps SDK, Fused Location Provider, Room, or any comparable libraries you are comfortable with; just keep the dependencies mainstream so future maintenance is simple. Acceptance criteria – The APK installs on Android 10+ without...

    I am starting a brand-new social networking mobile app and need an experienced iOS developer to take it from concept to App Store submission. The core platform will be iOS only, so deep familiarity with Swift / SwiftUI (or UIKit where appropriate), Apple Human Interface Guidelines, and the latest iOS SDKs is essential. The vision is a clean, modern community space where users can sign up quickly, create rich profiles, follow or friend one another, share posts that appear in a real-time feed, exchange direct messages, and receive push notifications that keep conversations moving. I already have initial wireframes and a feature wishlist; together we will refine them into a solid backlog, define the technical architecture, and set realistic milestones. Key deliverables: • Xcode p...
