I need a hands-on Twilio specialist to roll out two closely related pieces of work: • Programmable Voice – design and deploy the full call flow for our web application. That includes buying numbers, configuring IVR menus, call routing, voicemail, recording, and analytics. Everything should connect smoothly to our Node.js/Firebase backend through the Twilio Node SDK or Functions. • SMS Marketing – build a compliant Messaging Service for promotional campaigns, create templates, set up A2P 10DLC registration, scheduling, and deliverability tracking. Once live, you will monitor performance, run A/B tests, and refine copy or segmentation based on results. After launch I’d like ongoing support, so the engagement covers both the initial setup and day-to-day management of new campaigns and flow tweaks. Familiarity with Twilio Studio, Flex, and Python scripting for automation is welcome. When you reply, please reference similar voice or marketing projects you’ve completed, outline your approach to staying within carrier guidelines, and provide an estimated timeline for the first deploy plus the follow-up optimisation phase.

Hi, I'm Tamara Ashworth, owner of FlowSystem AI. My production system runs on Twilio today: I operate an AI voice agent for service businesses that buys numbers, routes inbound calls through IVR logic, records, transcribes, and books appointments, all wired to a Node.js backend. Your project is squarely inside what I already run live. For your two workstreams: - Programmable Voice: number provisioning, IVR menus, call routing, voicemail, recording, and call analytics, connected to your Node.js/Firebase backend through the Twilio Node SDK or Twilio Functions. I will map the call flow with you first, then deploy in stages so nothing breaks your web app. - SMS Marketing: a compliant Messaging Service with A2P 10DLC registration handled correctly from the start (brand + campaign vetting), reusable templates, scheduling, and deliverability tracking. I stay strictly inside carrier guidelines: registered traffic only, opt-out honored, throughput matched to your campaign type. After launch I can stay on for campaign management, A/B testing copy and segmentation, and flow tweaks as you learn what converts. Timeline: first voice flow and Messaging Service live within 7 days of access; 10DLC approval runs on carrier timelines and I will register it day one. Best, Tamara Ashworth Owner, FlowSystem AI

I've deployed several Twilio Voice systems with IVR routing, call recording, and Firebase integration, plus SMS campaigns with A2P 10DLC compliance and performance tracking. My approach: first, I'll architect your call flow in Twilio Studio with number provisioning and voicemail setup, then connect it to your Node.js backend via the Twilio SDK for real-time analytics and call logging. For SMS, I'll set up your Messaging Service, handle A2P registration with carriers, build campaign templates, and implement A/B testing infrastructure with delivery metrics. Post-launch, I'll monitor carrier compliance, run weekly optimizations on send times and copy, and manage new campaign deployments. Timeline: full Voice and SMS setup in 18-20 days, then ongoing optimization in phase two with weekly refinements based on your campaign data.
