    I need help wiring my application up to ElevenLabs so that text can be converted into natural-sounding speech on demand. The core task is to hit the ElevenLabs TTS API reliably, return the audio stream, and make it available for playback or download inside my product. I have not settled on a specific programming language, so whether you prefer Python, JavaScript, or something else that works smoothly with REST endpoints and WebSockets, feel free to recommend the best path. Likewise, I am open to ideas on adding extras—voice cloning, accent or speed tweaks, or any of the voice-quality controls that ElevenLabs exposes—if you can implement them cleanly.

The core pages are a polished Homepage, an About Me section that reads well on any screen, and a Portfolio Gallery where my work is showcased with smooth, React-powered animations.

    I need a lightweight, browser-based to-do list that is built entirely with Python on the back end and plain HTML/CSS templates on the front end—no JavaScript frameworks or external languages. A minimal Flask or Django setup is fine as long as the whole stack remains Python-driven. Core requirements • Users must be able to add new tasks, edit existing ones, and mark items as completed. • No sign-up or login flow is required; the moment the page loads, the list should be ready to use. • Data can sit in an in-memory store for now (SQLite or a simple JSON file is acceptable) as long as it persists while the server is running. Please set up a clean project structure, document how to start the server in a single command, and include a brief README covering insta...

    ...“tell-me-you’re-human” line (a small honeypot or hidden text field works) at the very bottom of the relevant Joomla forms so any script that doesn’t follow instructions is blocked before it ever reaches my inbox. You’ll need to: • Locate the template files or form extensions currently in use. • Insert the extra line / field cleanly without disturbing existing styling. • Write the PHP or JavaScript check that refuses submission if the field is filled (or the keyword is missing). • Test everything on both the staging copy and the live site to make sure genuine visitors have zero friction. • Provide a brief note of the edits so I can replicate them after future updates. I don’t want reCAPTCHA or anything that...

The rest of the site will stay visually as-is, but any SEO tweaks that cascade beyond the homepage are welcome. Deliverables I need to sign off on: • High-fidelity mock-up of the new homepage. • Responsive front-end build (HTML5, CSS3, JavaScript) integrated into our existing codebase. • Refactored navigation that works seamlessly on desktop and mobile. • A short SEO report outlining the changes implemented and the expected impact.
