    I’m launching an e-commerce jewellery brand and need a sourcing expert who can quickly connect me with a reliable factory able to produce custom, waterproof necklaces at the lowest possible price point. My collection will include gold-plated, silver and stainless-steel pieces, so the manufacturer must already work with all three materials and guarantee long-lasting plating that will not tarnish with everyday wear. You will research, vet and present manufacturers—ideally in regions known for competitive unit costs—who can handle small initial MOQs yet scale up as the brand grows. I also need confirmation that they offer private-label packaging, assist with custom designs, and can ship globally. Deliverables (discrete and specific): • A shortlist of verified manufact...

Accuracy and a clean presentation matter more to me than volume—I’d rather each letter look perfect than rush them out. Once everything is dispatched, I’ll consider the job complete when I have: 1. A folder of the finalized digital files. 2. The tracking sheet showing send dates for email and post. 3. Confirmation receipts or scans of the mailed envelopes (just a photo is fine). Let me know your estimated turnaround time and any questions you still have about the mailing list or postage logistics, and we c...

    ...completed, current quiz scores, and weekly streaks; teachers or parents should be able to glance at the same data on a lightweight dashboard. Think Firebase or an equally quick cloud back-end for syncing, but I’m open to the stack you prefer as long as the data stays secure and the UI remains snappy on entry-level Android phones. Core deliverables (acceptance criteria): • Android APK + source (Kotlin or Java) compiled against the latest stable SDK • Audio-first lesson player with play / pause / seek and buffered streaming for low-bandwidth connections • Gesture-friendly interactive activities (drag-and-drop, tap to match) that tie directly to the audio content • Quiz engine supporting multiple-choice, fill-in-the-blank, and picture-based pr...

    ...doctor’s profile (photo, specialty, brief bio, available hours). • They pick an open slot and confirm the booking. • A push notification reminds them as the appointment approaches. That’s the heart of it. I am open to your preferred stack, yet an Android-native build in Kotlin or Java via Android Studio will likely keep things straightforward. If you already have experience wiring notifications through Firebase Cloud Messaging—or a comparable service—please mention it. Deliverables 1. Full Android source code with clear project structure. 2. Debuggable APK for testing and a signed release build. 3. Short hand-off guide covering how to update doctor data and modify notification timing. Acceptance criteria • Smooth...

    ...birth, ID numbers, etc.) has to be filled. Basic validation—presence checks and simple format rules—is sufficient; anything more can stay out of scope for now. • The end result should feel native: once the API call succeeds, the user sees the customer screen with every mapped field in place and can immediately continue the usual onboarding process. Deliverables I expect: 1. Integration code (Java / PL-SQL wrapper or preferred Flexcube extension) committed to a Git repository. 2. Mapping document that shows each JSON field and its corresponding Flexcube column. 3. Simple test script or Postman collection proving the end-to-end flow. 4. Brief deployment notes so our ops team can move it from UAT to production without a hitch. If you’ve wo...

A successful Harley-Davidson dealership… thriving in a competitive market. But beneath the numbers… there was a story no one expected.” If you want it: • More corporate → I’ll tighten it • Darker / more dramatic → I’ll lean further into suspense • Neutral documentary → I&rs...
