Build Twilio Dialer & SMS Platform

I need to move fast on a Twilio-based application that combines a browser dialer, detailed call/SMS logs, in-app number purchasing for any available country, and a seamless payment flow for my clients’ subscriptions and top-ups. You will either extend my current codebase or spin up a clean implementation—whichever gets us to production quickest—while keeping the interface crisp and responsive on both desktop and mobile. Here’s what the finished solution must do: • Log every inbound and outbound call and SMS in real time, with searchable filters. • Provide a web dialer that connects through Twilio Programmable Voice. • Allow users to purchase and assign Twilio numbers from multiple countries inside the app. • Send and receive SMS using Twilio Messaging, with delivery receipts visible in the same log view. • Process client payments for plans, credits, or one-off number purchases using a mainstream gateway (Stripe, PayPal, or a comparable API you can wire in quickly). • Offer an admin dashboard where I can see usage, revenue, and error alerts. Acceptance criteria 1. All core functions demonstrated live on a staging URL. 2. Clean, documented source pushed to my Git repository. 3. Clear instruction sheet for adding new countries, pricing tiers, and payment plans. 4. No hard-coded credentials; Twilio keys and gateway secrets must load from environment variables. Tech is flexible, but past success with Twilio, Node.js or Python, a frontend framework (React/Vue), and secure payment APIs is essential. If you can start immediately and hit the ground running, let’s get this shipped. Budget: USD 15–25
