    ...front-and-center. Here’s the flow I have in mind: • You prepare a simple JSON file that lists every page and the visual concept for that page (character pose, key props, setting, mood, colour cues, etc.). • Using any AI image tool you prefer—Midjourney, DALL-E, Stable Diffusion—generate artwork that closely matches each concept. The goal is a cohesive, appealing style; near-replicas of the reference images I’ll share are fine as long as copyright is clear. • Lay the images and text into Canva (or similar) so I receive a press-ready PDF plus the editable design file. • Keep the text minimal, readable, and positioned so it never distracts from the scene; the pictures should do most of the storytelling. Deliverables 1. J...

    I need a fully-functional webhook inside the Meta Developer platform that ...through token verification, to delivering a small, well-documented endpoint that I can drop onto my own server (language is your choice, as long as it uses standard REST practices). Deliverables • Meta app configured with the “message received” WhatsApp webhook subscription • HTTPS endpoint source code that handles the GET verification challenge and POST payloads, then logs or echoes the raw JSON so I can extend it later • Clear, step-by-step setup notes (app settings, callback URL, token placement) so I can recreate the flow in another environment if needed When you apply, link to past work showing similar Meta or WhatsApp API integrations—this is the one detail I...

    ...a connection between SingleComm (Call Center Cloud System) and Hubspot via a middleware connector that receives a webhook from SingleComm upon call completion and creates an associated Call Engagement in HubSpot. 2. Middleware piece must handle the lead lookup logic. It cannot push "orphaned" call logs and expect HubSpot to link them later. 3.

Creation: * If a Contact is found: Create a Call Engagement associated with that contact_id. 3.3. If NO Contact is found: (Optional) Create a new Contact first, then associate the call. 3.4. Logging: Middleware should log successes/failures for troubl...

    ...uploaded logo image (PNG or JPG) together with a video file and then return every instance of that logo throughout the clip. The videos that come in will be MP4, AVI, or MOV, and the solution must run smoothly. Here’s how I picture the workflow: • The script accepts the logo and video paths from a simple CLI or minimal API endpoint. • It scans each frame, flags every logo hit, and outputs a tidy JSON or CSV that lists, for each detection, the start timestamp, on-screen duration, and bounding-box coordinates. • No extra training or fine-tuning whenever a new logo is supplied—the detector should work right away with whatever image is uploaded. I’m after well-commented, maintainable code, and I’ll need brief setup instructions so I can ...
