These glitches appear on the home page, every product page and even at checkout, so conversion is taking a hit.

    Cross-Device Data Sync System Development
    18 годин(-и) left
    Верифіковано

    ## Project Description Develop a secure cross-device synchronization system for an existing React web application and React Native mobile application. The applications store machine-learning generated data locally, including face embeddings, vector embeddings, media metadata, and versioning information using IndexedDB (Web) and SQLite (Mobile). The objective is to enable automatic synchronization of data between a user's authorized devices while minimizing network usage and avoiding full database transfers. The solution should support Web-to-Mobile, Mobile-to-Web, and Mobile-to-Mobile synchronization through efficient device discovery and bi-directional data exchange within the LAN/Wifi network. The synchronization process must transfer only new or updated records, prevent duplicat...

    Samsung S20 Ultra Data Unlock

    My backup phone - a Galaxy S20 Ultra is currently frozen behind a forgotten screen password/PIN, yet it is fully mine and I can provide the original proof-of-purchase immediately. I need the handset unlocked without triggering a factory reset because every contact, message, photo and video stored on the internal memory must remain intact. Deliverable - to be done online ofcourse , you give instructions and I follow • Device unlocked and booting to the regular One UI home screen, all data present. Timeline is flexible for a truly safe solution, but the sooner I can reach my data the better.

    I need a focused Android build that lets users sign up or log in securely and receive real-time push notifications. The core of the job is to: • set up robust user authentication (email / password and social login options are both fine as long as they follow current Android best practices); • wire the app to a reliable push service—Firebase Cloud Messaging is my default choice, though I’m open to an alternative if you can justify it. Everything else—UI polish, extra features, store submission—can follow later. For now, I want a clean, well-structured codebase that I can extend. Please use Kotlin where possible, document the key classes, and make sure the build runs without errors in Android Studio. Deliverables 1. Full Android Studio project folder re...

    I’m building an Android app that must ship with truly robust, “ethical-hacker-grade” protection. The single most important piece is a custom security module that monitors everything users do inside the app and flags anything suspicious. Here’s what I need you to deliver: • A lightweight, unobtrusive activity-monitoring component that captures user behaviour events in real time. • Intelligent tracking logic: distinguish normal navigation from potentially risky actions, then push those events to my existing backend through secure, encrypted calls. • Clear, well-structured code (Kotlin or Java) plus concise documentation so I can maintain and extend the module later. • A quick demonstration APK and companion README showing how to plug the c...

    I’m ready to build a brand-new website and I’m looking for a developer who can guide the entire process—from picking the right stack to launching the finished site. While I haven’t locked down the specific category (e-commerce, portfolio, blog, or something hybrid), I do know I want a modern, responsive experience that loads quickly, looks professional on every device, and is easy for me to update afterward. Here’s how I picture the collaboration working: • You’ll advise on the best platform or framework based on my goals and budget. • Together we’ll map out the site structure and user flow, then turn that into clean, mobile-first page designs. • You’ll build the front-end and any required back-end or CMS functionality, t...

    Modded Utility APK Needed
    4 годин(-и) left

    I need a fully-functional modded APK for an existing Android utility app. The goal is simple: strip out every advertisement, unlock all premium features that normally sit behind a paywall, and apply a fresh custom theme so the interface feels cleaner while still matching the original layout. Because I use the app daily, stability is critical. The patched build must install over the current Play-Store version without forcing me to uninstall, preserve my user data, and launch without triggering Play Protect warnings. Please keep the original package name and signature scheme unless there’s a technical reason to re-sign—just let me know first. I’m looking to receive: • One signed, ready-to-install APK (latest app version) • A brief changelog or notes outlinin...

    Auto Ride Acceptance Android App
    3 годин(-и) left

    I need an Android application (APK only, no iOS for now) that can automatically accept incoming Rapido and Ola ride requests the moment they appear, then surface a simple confirmation screen to the rider. Core workflow • User opens the app and signs in with Firebase Authentication. New users must verify their phone number through an OTP flow. • From the home screen the driver can toggle Ola or Rapido acceptance on or off independently; when a service is switched off, no rides from that platform should be auto-accepted. • Whenever the toggle is on, the app stays in the foreground/background (your call on the best technical approach) and listens for ride offers. Matching offers must be auto-accepted in milliseconds, mimicking the speed of native Ola / Rapido acceptanc...

    I rely on an auto-clicker to keep the Ola Driver app running smoothly, but the latest Ola update now shows a screen-wide blocker that stops any touch automation. I need a developer who can give me back that hands-free convenience. Here’s what I’m after: if you can simply unblock my current auto-clicker, great. If that proves impossible, then I’m happy to commission a brand-new Android app that reproduces the same auto-click features while cleanly bypassing the new blocker. I’m unsure whether I still have full source code for the existing tool, so please plan for both scenarios. Core requirements • Seamless auto-click functionality inside the newest Ola Driver build • Reliable bypass of the overlay/blocker screen introduced in the recent update &bul...
