    ...in with the classic username-and-password flow, a user should be able to choose an amount, see (or pre-fill) my banking details, and push the payment through an integrated bank-transfer API. Security is critical, so the credential flow must be encrypted end-to-end and the transfer requests signed or otherwise verified to prevent tampering. A lightweight backend—REST or Firebase Cloud Functions is fine—can manage authentication, session tokens, and payment-status webhooks. Please deliver: • Full Android Studio project (Java or Kotlin) • Secure username/password authentication flow • Bank-transfer API integration with success/error callbacks • Simple UI: login, payment form, history screen • Buildable APK plus source code in...

    I already have a feature-rich marketplace site—events, ticketing, Zoom rentals, medical-service comparison, facility catalogs, bookings, community forum, AI-based search engine, AI chatbot, role-based chat, escrow wallet, vouchers, points, local payment gateway, and Zoom API are all live in the build. The overall user flows are mapped, yet the five role dashboards (Admin, Event Organizer, Health Worker, Healthcare Facility, Patient) fall short of that blueprint. Your first mission is to bring every dashboard up to spec. I want consistent, responsive interfaces that expose exactly the tools each role needs. For the Admin space, all three critical pillars—user management, analytics & reporting, and permission settings—must be rebuilt so I can monitor activity, ...

    I need a developer to create a dedicated communication-management tool that runs natively on Linux. The core requirement is the ability to establish, track, and gracefully close sessions over both TCP/IP and UDP. All connection handling, queueing, and basic error management should happen inside the tool so that client applications can speak through a clean, well-documented API instead of implementing their own socket logic. This tool must be system centric installed on our Linux server Here is what I have in mind: • Command-line operation is fine for the first iteration, but please structure the code so a lightweight GUI or web dashboard could be bolted on later. • Clear logging of connection events, dropped packets, and throughput statistics is essential—I’...

    I’m building a high-end real-estate lead engine that can capture, qualify, and route 150–200 fresh inquiries every week with a hard 99.5 % uptime target. Instead of a generic chatbot, the core of this MVP is a lightning-fast Custom Qualification UI written in React, backed by a Node.js API and a PostgreSQL (or comparable SQL) data store. What I need from you is end-to-end ownership of the stack: solution architecture, clean code, robust testing, and cloud deployment. The product must open the door for future add-ons such as a real-time analytics dashboard, but for this first milestone the focus is on: • Lead scoring system that assigns quality grades the moment data arrives • Automated lead routing that pushes hot prospects to the correct broker or CRM qu...

    I’m building a B2B platform that now has to expose a well-structured REST API so other services can hook in without friction.
