The work spans thoughtful UI/UX design through to a fully coded, responsive frontend.

    Dynamic Zoom Webinar Tech Host
    2 días left
    Verificado

    I’m running a two-hour Zoom webinar on 17 April for roughly 100 attendees and I need a sharp, fast-moving technical host to keep everything running like clockwork. The core of the job is full backend control: setting up Zoom, loading and advancing the slide deck, cueing videos, spotlighting each speaker at precisely the right moment, and maintaining a smooth run-of-show. Live attendee support is equally important—admit people, moderate chat and Q&A, troubleshoot audio or video issues on the fly, and keep the energy up without letting distractions leak on-screen. Two elements sit at the very top of my priority list: • Embedding polls at pre-planned breakpoints and sharing results instantly • Automatically generating and distributing post-event attendance cert...

    I’m building a document-automation system that can create, manage, and store Contracts and Reports whose actual content is in Arabic, while every interface element (menus, buttons, error messages) stays in English. Scope • One responsive web app plus companion iOS and Android builds—feel free to suggest React, Flutter, or any stack you trust for a single shared code-base. • Full right-to-left support so Arabic text renders perfectly and exports cleanly to PDF. • Template-driven assembly: I choose a template, drop data into the fields, and the app instantly produces the final document ready for download or archival. • Cloud or on-prem storage with search and retrieval from any device. Deliverables 1. Production-ready web application deployed t...

    I need a skilled developer to build a fully autonomous bot that can play — and consistently win — a browser-based online pool game. The work begins with reverse-engineering the game’s HTML5/JavaScript interface so the bot can read every element that matters: ball positions, cue orientation, timers, and opponent moves. From there, I expect an intelligent decision engine that weighs angles, spin, power, and safety shots, always aiming for the highest percentage play. Finally, the bot has to fire those shots inside the browser with smooth, human-like mouse movement and timing to avoid detection. Because the core challenge touches three distinct areas, the milestone plan looks like this: • Interface hook-up: reliable, real-time extraction of table state and cue controls...

    I have a DWIN display that needs to be configured in DGUS so the end-user is greeted by a clean, single-level menu and can move through it with straightforward tap actions. The project is intentionally simple: no nested pages, no elaborate gesture control—just clear navigation that presents text, numbers, a handful of icons, and a few responsive buttons. All graphic assets and wording are ready on my side; what I am missing is the DGUS project file that ties everything together, loads smoothly on the screen, and reacts instantly to each tap. Please organise the fonts, image libraries, and variable areas properly inside DGUS, map each touch area to its function, and export a final .BIN (or .KXD) along with the editable project folder so I can flash it here. Acceptance criteria &bu...

    I need a small yet reliable program that can read the full contents of a Word document containing complex layouts—text, images, tables—and compare it against the corresponding content found in either an HTML page or a PDF file that is equally rich in formatting. The purpose is to generate a clear, detailed comparison report that tells me where wording diverges, which tables differ, and whether any images or captions have changed. You are free to choose the language and libraries you find most efficient (Python with python-docx, BeautifulSoup4, pdfminer or PyPDF2 is perfectly fine; a C# or Java solution using Apache POI, iText, etc. is equally acceptable). What matters is that the script: • Extracts all textual segments in reading order from both sources, even when they a...

    I support several enterprise customers running Avaya Experience Portal (AEP) with CTI applications that communicate through Avaya Aura Application Enablement Services (AES). To keep pace with their evolving requirements I need fresh code as well as updates to existing voice and desktop CTI components, all of which must slot cleanly into their wider CRM and reporting stacks. Scope of work New modules will handle intelligent call-routing logic, IVR customisation (prompt control, dynamic menus, backend look-ups) and detailed data reporting. Alongside that, some legacy Java and C# services require refactoring for stability and performance, and a set of JavaScript widgets must be wired into web-based agent desktops. Integration points include REST/JSON services, databases, and third-party an...
