    I need constant coverage on a consular-booking website: 35-50 DAILY clicks on the “Search / Next” button spread across the entire day, every day, for the next 45 days. The moment a slot appears, complete the booking and immediately forward the email confirmation to me—this email is the sole proof of success and will trigger an additional payment. You may click manually or use a low-profile tool such as Selenium, iMacros, or a custom script; whichever method you choose must keep the session active and undetected by the site.

A few transformation links have recently started breaking and I’d like someone who knows the platform inside-out to jump in, fix the immediate issues, and stay available for incremental improvements as we grow. The core task that is working is a small PNG watermark that sits in the top-left corner. The other more important flow is a stitch of two videoes. here is the logic. A user uploads a video (mp4) and saves it to his profile. He creates a custom video and can choose an option to add an intro and watermark. We have the stitching working, but need it working with the cloudinary API so that any intro of any length from 2-5 seconds as an mp4 is stitched to the main video. The final r...

    I’m looking for a seasoned WordPress developer with roughly three to five years of hands-on experience who can jump straight into advanced plugin work, theme tweaks, and performance-minded database tasks. You should feel entirely at home with PHP 7+ and object-oriented patterns, know MySQL optimization inside out, and be able to blend clean HTML5, CSS3, JavaScript, and jQuery into whatever you ship.

If you feel a bar chart could add value I am open to that, but it is not essential. The app must launch natively on both iOS and Android from a single codebase, so a framework such as Flutter or React Native makes the most sense.

    I’m assembling a small, Poland-based team and need an experienced full-stack developer who is fluent in Polish. The immediate focus is a web application where the backend is already outlined around Node.js (Express, TypeScript preferred) and the frontend will be built with Vue.js 3 and Vite. Your day-to-day will involve: • Designing and building new features end-to-end, from database schema to responsive UI. • Writing clean, testable JavaScript/TypeScript code on both client and server. • Integrating RESTful endpoints and WebSocket streams. • Participating in code reviews and architecture discussions—communication in Polish is essential because the rest of the product team and stakeholders speak it exclusively. Tech stack in scope: Node.js / Express ...

    I’m looking for a strong front-end engineer who can join the team for the next few weeks and push our Vue codebase forward. Everything you touch must run on Vue 3—Vue 2 is already out of the picture—so deep knowledge of the Composition API, script setup, and modern build tooling is essential. Your main mission is to take our existing library of modular UI components and refactor or extend them so they can be dropped into multiple products without a performance hit. We already have a basic style guide; you’ll respect it, but you’ll also make sensible calls where it falls short. The legacy parts of the platform still rely on Twig templates (PHP + HTML + CSS + plain JS), so an eye for how your Vue widgets slot into those views will help you move quickly. Perf...

    I need an AI chat agent built from the ground up to take over real-time customer service across a dedicated WhatsApp line. The bot must greet visitors instantly, understand their questions in multiple languages, and return clear, relevant answers without sounding scripted. When the query falls outside its scope, it should hand the conversation to a live agent smoothly while keeping full context. Key expectations • Seamless installation on my existing site (JavaScript snippet or widget) and connection to my verified WhatsApp Business account through the official Cloud API. • Natural, conversational responses in at least English and Spanish to start, with the framework ready to add more languages easily later. • A simple dashboard where I can upload FAQs, product manua...

    My WordPress site is showing an issue I need resolved quickly, and once that’s done I’d like several adjustments made to the current theme. I have the theme files ready; what’s missing is a developer who can dive in, locate the problem, patch it cleanly, and then tailor the theme so it looks and behaves exactly the way I want. The immediate priority is troubleshooting and fixing the bug that’s interrupting normal site behaviour. After that, I’ll be asking for theme-level changes—potentially tweaking the layout, reworking colours, or building out new template sections—so a solid grasp of PHP, CSS, JavaScript, and the WordPress template hierarchy is important. I’m open to suggestions on best practices or smarter ways to achieve the look and fu...
