Robust security is non-negotiable, so the build must include Two-factor authentication, end-to-end Encryption, and smart Fraud detection baked into every transaction flow. To keep the scope crystal-clear, here’s what I must walk away with: • A scalable back-end capable of handling the three payment methods above • Front-end or SDK components that drop into web apps, native mobile apps, and common POS terminals • Security layer implementing the three features named earlier, with compliance reporting enabled • Clean API documentation and a minimal admin dashboard so I can track transactions and manage keys I’ll consider the project complete once test transactions for each...

I need someone who can decompile that executable, clean up the recovered code, and then refactor the tool so it runs purely from the Windows command prompt. Instead of the current dialog box, the new build must accept: • a start time and end time parameter that define the export window • a list of one or more phone extensions to filter the recordings Everything else about the workflow stays the same: the program will talk to the recorder SDK, fetch the selected recordings, and drop the files into a local folder on the same server where the recorder so...

I also need a branded splash screen while the content loads, an adaptive app icon that follows Android guidelines, and basic native navigation such as back-button support and a graceful offline/error page. Feel free to use Kotlin or Java, but the project has to target the current Play Store SDK level and be fully ready for submission. Deliverables • Android Studio project with all source code • Release-ready AAB & signed APK for internal testing • Firebase (or similar) push notification setup with simple test message proving delivery • Instructions to update future app icons and splash screens, plus a short README on rebuilding I’ll p...

    ...and marketing visibility. Your job is to wire the apps into Firebase and connect the data flows to two ad networks: Facebook/Instagram Ads on the Meta side and Google Ads. Here is what I’m expecting: • Add the latest Firebase SDK, configure the project for both bundles, and verify that core events, user properties, and in-app purchase data reach the console in near real time. • Link Firebase to Google Ads so conversions and audiences sync automatically, then test with a live campaign to confirm the attribution loop is closing. • Integrate the Facebook Ads SDK, map the same key events, and make sure they surface in Events Manager; this includes setting up the required App ID, deep-link support, and deferred install measurement. • Provide...

    A native Android application that turns the sales phone into a card terminal, embedding SumUp's Tap to Pay SDK to read contactless cards over NFC. No separate card reader. How it fits. Two applications on one device. The Odoo POS is a Progressive Web App, built separately, and launches this app when the operator selects the card payment method. How the flow works. A PWA cannot receive an Android activity result, so the two apps never exchange the outcome directly. The POS passes a transaction identifier by intent. The app fetches the authoritative amount from the Odoo server over its own authenticated call, runs the payment through the SDK, and posts the result back to the server — which then updates the payment line in the POS. The amount never travels in the in...

    ...The core of the assignment is the SDK/API itself; later we will drop it into an Android app, so please architect everything with clean interfaces, documented calls and minimal external dependencies. Accuracy, fast initial fix, and smooth hand-offs between floors are crucial. Stairs, elevators, escalators, corridors, gates and individual rooms must all be routable, and the engine should always calculate the optimal path, then automatically reroute if a visitor strays. Deliverables • Parsed and structured multi-floor map (2D & 3D layers) generated from the supplied plans • BLE-sensor-fusion positioning module showing real-time location & orientation • Turn-by-turn routing with dynamic reroute logic across floors and vertical connectors • Well-docu...

    Claude will be the backbone of a new natural-language-processing system that I’m putting in place for my product. The initial scope centres on three capabilities: reliable text cla...demo scripts that show the system responding to fresh inputs. • A concise deployment guide so my internal developers can reproduce the environment on AWS or GCP. Acceptance criteria: every model should reach at least 85 % macro-F1 on our hold-out set, and the chatbot must answer at least 8 of 10 predefined queries correctly during a live test. If you have recent experience with Claude’s SDK, LangChain, or similar orchestration tools, this will move fast. Feel free to suggest additional metrics or workflow improvements—clarity, reproducibility, and clean code matter more to...

    ...• Users land on any of the three touchpoints and are greeted by the bot. • Natural-language understanding recognises intent and pulls answers from our knowledge base, product catalog, and order-management API. • When confidence is low or escalation is requested, the conversation hands off to a live agent with full context. Essential requirements • Multichannel deployment (web widget, in-app SDK, Facebook/Instagram Messenger, and WhatsApp Business). • Conversational AI stack such as Dialogflow CX, Rasa, Microsoft Bot Framework, or an LLM-based custom backend—whichever provides seamless intent detection, entity extraction, and multilingual support. • Secure integrations: REST/GraphQL for order look-ups, Stripe for payment-related questio...
