The second script re-splits the translated content into properly timed captions for delivery.

The project manager then continues with the workflow. Once the translated content is finalised, the project manager emails the files back to the script owner to run the second script, and the script owner sends the processed files back to the project manager for delivery.

    I already run on the WhatsApp Business API and now need it properly connected to Meta so I can handle both automated replies and bulk messaging from one place. Here is what I expect: • Map my current WhatsApp Business API number into Meta Business Manager, verify it, and activate webhooks. • Build out the automated flow reply I have in mind so it can answer customers instantly—this includes template approval inside Meta and any required server-side logic. • Enable a straightforward method for sending large-volume marketing broadcasts that stays within Meta’s policy limits (24-hour window, opt-in, template use). You may use Node.js, Python, PHP or another language you’re comfortable with, as long as the final solution is documented and ready for m...

    I have a very small Python snippet that prints “Tumi voter” when age is 18 or more and “Tumi voter na” otherwise. I want this turned into a clean, beginner-friendly example that actually asks the user for their age, validates the input, and then displays the same Bangla messages. The task is deliberately simple: create a single .py file that runs from the command line, requests the user’s age, handles non-numeric input gracefully, and prints the correct message based on the age entered. Keep the code concise, well-commented, and organised so it can be shown to new learners as a model of good practice in Python.

    I need a web-based hotel booking platform where travelers can type a U.S. ZIP code, instantly see nearby hotel options, and complete the reservation at the best agent-only rate by entering a valid IATA number at checkout. The core build must: • Pull live availability, pricing, and booking capabilities through direct API integrations with Amadeus, Sabre, and Travelport. • Offer traveler-facing search filters for price range, star rating, and specific amenities. • Display results sorted by distance from the entered ZIP. • Securely process the booking, verify the IATA, and return confirmation details in real time. I’m looking for a clean, responsive interface, clear documentation of each API connection, and deployment on a cloud host of your choice. Onc...

    I need a clean, self-contained FastAPI microservice that accepts an uploaded JPEG or PNG, automatically traces the outer contour of the visible subject, expands that shape by a configurable offset, and returns the resulting cutline as an SVG file. Auto-outline detection is the single most important processing step; edge smoothing and colour tweaks are nice-to-haves but not required for this phase. Here’s the flow I have in mind. A user hits /outline with a multipart upload, the API queues the image, runs the outline routine (OpenCV, scikit-image, or any library you prefer), inflates the path by the requested number of pixels or mm, then streams back plain-text SVG. A second, optional endpoint /health is enough for monitoring. The service must comfortably handle images up to roughly ...

    I need a sharp-eyed React front-ender to drop into my production SaaS site (React + Vite + Tailwind CSS + React Router) and give the buttons a final coat of polish. The rest of the interface is solid; the job is strictly UI/UX touch-ups—no backend work at all. What I’m after The focus is on enhancing button styles. Specifically, I want fresh colour treatments and smooth, consistent hover effects that feel at home inside the current Tailwind design system. I don’t have a preset palette, so I’ll rely on your suggestions for accessible, modern colours that complement the existing look. Adding icons isn’t on the table for this round, but I’m open to any quick wins you spot elsewhere once the primary task is settled. Deliverable acceptance • All button...

    I’m setting up a brand-new online store and want the entire build to run on Medusa JS. From the ground up I need: • Product catalog management that supports advanced inventory with variants (sizes, colors, bundles, etc.) • A smooth shopping-cart experience tied to a secure payment gateway • A fresh, custom design—there’s no existing wireframe, so you will shape both the look and the structure You’ll own the Medusa server configuration and extend it where necessary for variant logic, stock tracking, and order flows. On the front end, the goal is a clean, responsive storefront that showcases products clearly and converts well; I’m open to the stack you prefer as long as it pairs seamlessly with Medusa’s APIs.

    I need a TDL file to customize the Ledger Vouchers screen in TallyPrime by adding 4 specific features to the right-hand sidebar (Button Bar). Please check these requirements: 1. Web Link: Add a button. When clicked, it should directly open our website in the default web browser. 2. Show/Hide Narration: A toggle button to quickly show or hide the narration for all entries in the current ledger view. This helps in cleaning up the view when I am only looking at amounts. 3. Narration Filter: A search/filter button specifically for the Narration field. I should be able to type a keyword (e.g., 'Cash' or a specific 'Ref No') and the screen should only show vouchers containing that text in the narration. 4. Replace Ledger: This is for bulk editing. I want to select ...

    When my Android app is minimized, any YouTube video inside the WebView pauses immediately. I need a clean, reliable way to keep playback running in the background the same way the regular Here’s the current state of things: • I’m loading the video inside an Android WebView. • I have already experimented with various WebView settings—JavaScript, media playback flags, setMediaPlaybackRequiresUserGesture =false, etc.—but nothing has stopped the pause on “home” or “recent-apps” actions. • No alternative implementations (custom players, exo-player wrappers, or different WebView engines) are in place, What I need from you: 1. A working code solution (Java or Kotlin) that lets the video continue playing when the user switch...

    Netflix Clone with 2FA Auth

    I need a clean, responsive Netflix-style interface that relies on plain HTML5, Tailwind CSS and a touch of JavaScript. The visual side should mirror Netflix’s familiar dark theme, hero banner and thumbnail grid, but the real priority is a rock-solid user authentication flow secured with two-factor authentication. Here’s the flow I’m after: a visitor signs up with email and password, receives a one-time code by SMS or email, enters it, and only then gains access to the protected area. You’re free to use any mainstream service—Firebase, Auth0, Supabase, Twilio, etc.—as long as you document your choice and keep the setup straightforward. After login the user lands on a dashboard that shows placeholder movie cards arranged in a responsive grid. Actual stre...

    Our online apparel store needs a round of front-end refinements so every shopper sees our products at their best and breezes through checkout. The work is straightforward but important: • Homepage, product pages, and the full checkout flow all require code-level tweaks. • Product images must pop with optimized sizing, proper aspect ratios, and quick-load techniques. • Text across headers, descriptions, and calls-to-action needs cleaner styling and hierarchy for easier reading. • Light interactive touches, think hover states, subtle micro-animations, or dynamic size guides should be added without slowing the site. I’ll supply access to the current codebase, brand assets, and a staging environment. Your changes have to stay responsive, cross-browser frie...
