    I need help establishing a dependable, real-time method to follow one person’s physical whereabouts strictly for personal safety. The goal is to know where they are at any moment so I can react quickly if an emergency arises.

    I’m building a distribution-management application that talks directly to Tally Prime ERP so every sales order and payment stays perfectly in sync with our accounts. Two user groups will work inside the same system. • Internal staff need a dashboard where they can create, edit and track customer orders, then push the resulting invoices, receipts and ledger entries straight into Tally without manual export-import routines. Also check their regular tasks on the app assigned by their manager or owners. • External customers will log in to place new orders, review their status and download invoices. Their activity must feed our Tally data in real time (or on a scheduled sync you recommend) so inventory and receivables remain accurate. They can view their accounts on phone,...

    I’m building a single Android application that handles every step of small-business billing in one place. The core of the project is an all-in-one module that lets me: • generate professional invoices on the phone, • process customer payments in-app, and • track expenses in real time. Beyond those essentials, I also need the app to exchange data smoothly with my existing accounting software and CRM so client records, invoices, and payment statuses stay perfectly in sync. If a standard connector is not available, a lightweight REST integration is acceptable as long as it preserves data accuracy and runs securely. The finished APK (plus full source in Kotlin or Java) should: • run cleanly on current Android versions down to API 24, • store data locall...

    I am building a secure, user-friendly booking platform where patients can effortlessly find and reserve time with healthcare professionals and business consultants. Core workflow • Patients browse profiles, choose times, and confirm appointments. • On the provider side, consultants need three integrated tools: appointment scheduling, client management, and seamless payment processing. Patient-facing extras To stand out from generic schedulers, the platform must also let patients: • Store and review their own health records. • Start real-time online consultations (video preferred, voice and chat as fallback). • Receive automatic reminders by email, SMS, or in-app push. Technical notes & deliverables I’m open to your preferred stack, ...

    I need a Telegram bot that runs smoothly on mobile-friendly hosting and gives me a single, intuitive control panel to direct every aspect of post views on my channel. From that dashboard I want to decide exactly how many views each post receives, how fast they accumulate, and over what time span they appear. Beyond raw view counts, I also need flexible reaction management. The user should be able to pick any mix of Likes, Hearts, or Thumbs Up—so the bot must expose all three and let me toggle them per post. Core functions I expect: • Post limit rules so I can cap how many pieces of content the bot touches each day. • Full view settings (quantity, speed, timing) linked to scheduling logic. • Random-pattern views to keep activity organic. • Mute / unmu...

    My Swift-based iOS app is functionally complete, yet Apple keeps rejecting it for “App Store guidelines non-compliance.” The reviewer notes are vague, so I need a developer who knows the guidelines inside out to pinpoint the issue, correct it, and push the build through review. You’ll receive Admin access to App Store Connect, the current Xcode project, and the reviewer messages I’ve received so far. I’m happy to supply test credentials, privacy-policy copy, or any extra metadata you need. Please assess the project, map each rejection note to the exact guideline, make the required code or metadata changes, and handle the resubmission until the app is approved. Familiarity with Xcode, Swift, StoreKit, privacy entitlements, and Apple’s Human Interface Gu...

    My in-house team has brought our React Native mobile app close to the finish line, but we still need an experienced developer to push it over. The remaining work is entirely on the front end: polishing outstanding features, fixing the small bugs that pop up during edge-case testing, and—most importantly—making sure every screen matches the approved Figma design pixel-for-pixel. I will continue handling the backend and API endpoints, so your focus stays on React Native UI logic, component optimisation, and any native module tweaks needed for a smooth release on both iOS and Android. Once you are done, I expect a clean codebase, updated Figma-accurate layouts, and store-ready builds for TestFlight and Play Console. If you have a strong eye for detail, know your way around React...

    My mobile app—built around Google’s AI services—is already taking shape, but only on the front-end side. I have functional screens and basic flows coded in a cross-platform framework; what is missing is the server layer that ties everything together. I now need a developer who can complete the backend integration and push the finished product live on both the App Store and Google Play. Here is what’s left to do: • Connect the existing front-end to a robust backend (Firebase, Google Cloud, or another secure stack you are comfortable with). • Implement any required API endpoints so my AI features run smoothly and fast. • Configure build settings, signing, and store assets, then guide the app through the review process on iOS and Android until it ...

    I need a single code-base application that runs smoothly on iOS, Android, and the web to streamline how our staff handle Banquet Event Orders (BEOs) and other operational paperwork. The user journey is straightforward: a team member uploads or photographs a scanned document, the system applies OCR to pull out every relevant piece of text, numbers, and even embedded images, and then presents a verification screen so the data can be confirmed before it is locked in and routed through our internal workflow. Core flow • Capture: camera, drag-and-drop, or file picker for PDFs/JPEGs. • Extraction: high-accuracy OCR that recognises text, numeric fields, and images. • Verification: editable review stage with role-based access (submit, verify, approve). • Export: struct...
