...below in one place: • Hotels • Car rentals • Spa packages • Local tours The system must recognise three user roles—Guests, Service providers, and Admin—each with its own dashboard and permissions. Core flows include real-time availability search, price and inventory management for providers, secure checkout, and a clean admin console for oversight and reporting. I’m flexible on the tech stack, but modern, well-documented frameworks (think React or Vue on the front end, Node.js, Laravel, or similar on the back end) and RESTful or GraphQL APIs are preferred so the platform can scale. Payment gateway integration (Stripe, PayPal, or your recommended option) and mobile-responsive design are essential. Deliverables • Fully function...

...showing queued, sent, failed, and delivered counts. • Simple REST or HTTP API so my existing CRM can trigger sends. • Basic sender ID or shortcode handling in markets that allow it. I’m open on stack—Laravel, Node, Python, or Go are all fine as long as the UI stays clean and performance scales. If you already work with Twilio, Vonage, Plivo, or any SMPP gateway, mention that in your proposal. Voice broadcasting isn’t in scope for this phase, but I’d like the architecture to be modular enough to bolt it on later. Send me a detailed project proposal outlining: • Your recommended tech stack and why • Key milestones with timelines • Any assumptions (e.g., gateway costs, server specs) • A brief plan for testing...

...trunk platform configured to issue USA DID numbers and deliver ready-to-use SIP credentials for a blended (inbound + outbound) call-center environment. The system has to sustain 51–200 concurrent calls with consistent audio quality and tight security. Call recording, an IVR designer, and detailed call analytics/reporting must be native features, not bolt-ons. I am happy to work with an open-source stack such as Asterisk or FreeSWITCH, a commercial carrier API, or a hybrid approach—whichever lets us scale quickly while keeping ongoing costs predictable. TLS/SRTP support, automatic fail-over to a secondary trunk, and the ability to order, port, and manage DIDs on demand are essential. Deliverables • Deployed, fully tested SIP trunk platform with at least one li...

I’m building a web-based t-shirt and logo designer that runs smoothly in any modern browser, and I need a JavaScript pro to code the heart of the experience. The core of the job is a custom design tool where shoppers can create their own graphics directly on a virtual garment. The tool must let users drag and drop images or icons, stack those elements in adjustable layers, and style text with a solid range of fonts, sizes, colours and basic effects. A lightweight, responsive canvas solution—, Konva, or comparable vanilla-JS work—is fine as long as it stays fast on desktop and mobile.

I have a nearly finished cryptocurrency payment gateway that lets online merchants accept TEXITcoin (TXC) and PUREmedal (PURE). The core smart-contract logic, checkout flow and database schema are already in place, and the stack is React on the front end with a Node.js back end.
