    Web Panel for 3Proxy Management
    6 dni left
    Zweryfikowany

    I need a web-based administrative panel that lets me oversee several IPv4 proxy servers running 3Proxy from one place. The panel should: • Auto-configure new or rebuilt servers, applying 3Proxy settings and firewall rules without manual SSH work. • Push software updates, configuration edits, and security patches to every connected host remotely. • Expose a documented RESTful API so other systems can create, suspend, rotate, or delete proxies programmatically. • Support multiple user roles—at minimum Admin plus one or more limited roles—with a clean permissions model. • Display real-time status (online/offline, traffic, errors) and basic analytics for each proxy. A straightforward, responsive UI is essential; think login, dashboard, server list...

    I’m ready to build a full-featured e-commerce web application and need a developer who can take the idea from concept to deployment. The core goal is to deliver a fast, secure online store that works flawlessly on desktop and mobile browsers. What I already know: this is a software-development job, not marketing or design in isolation, and the deliverable must be a web application, not a mobile or desktop installable. Scope of work • Plan and propose the tech stack that best balances performance, scalability, and ease of maintenance. Popular choices like React or Vue on the front end and Node, Django, Laravel, or similar on the back end are all on the table—convince me why yours is the right fit. • Design a clean, intuitive UI/UX with responsive layouts. &...

Key functionality I must see in the first release: • Robust booking system that supports real-time availability, rescheduling, and cancellations. • Detailed provider profiles showing qualifications, services offered, pricing, and photo galleries. • Ratings & reviews attached to completed jobs to build trust and drive quality. • Secure payment-gateway integration for in-app card payments and futur...

    I need a lightweight, browser-based tool that takes three inputs—Vendor profile, Opportunity details, and Scope of work—and turns them into a well-structured business proposal with a single click. My first thought is to call OpenAI GPT-3 for the heavy lifting, but I’m happy to lean on any genuinely free language model or API you recommend as long as the quality stays high and the running costs stay negligible. Core flow • Clean web form where I enter the three data blocks above. • The app sends this data to the chosen AI engine and receives a draft. • A rich-text editor opens the draft so I can tweak, reorder, or add sections on the spot. • A simple template selector (fonts, colours, headers, logo placement) lets me re-skin the document before e...

    Our dApp’s React-based frontend is live, but the UI stalls whenever it talks to our smart contracts—data can take seconds to appear, and some calls never resolve. Wallet connection and basic transaction flow are in place, yet my top priority is tightening the UI interaction layer so every contract read or write feels instant and reliable. You’ll start by cloning the existing repo, running the current build, and profiling exactly where the slowdown happens. From there, I need you to refactor or replace the offending code—whether that means reworking our hooks, introducing multicall batching, tidying up state management with Redux or Zustand, or simply catching silent promise rejections.

We access them remotely using EZVIZ PC Studio, which is mainly designed for home or small installations and not suitable for professional monitoring. Important note: EZVIZ H9C cameras do not provide RTSP streams, so the system will likely need to use the EZVIZ Developer Platform (Cloud API / SDK).

    Our shopping site is already up on a React-Node-MongoDB stack; now I need an experienced developer to take it over the finish line. Your main focus will be sharpening functionality, with special attention to robust search and filtering so customers can locate products quickly and intuitively. While you’re in the codebase, I also expect you to hunt down lingering bugs, tighten performance, and give the interface a final polish so it feels modern and consistent across devices. You will be working in a familiar environment—React (hooks, context or Redux), Express API, and MongoDB Atlas—so solid experience with that trio is essential. If you can blend in UI frameworks like Material-UI or Tailwind without bloating the bundle, even better. Key deliverables • Functional...
