WhatsApp or Voice AI Assistant — production-ready, with human handoff

About this Gig

A customer-facing AI assistant on WhatsApp or voice, live on your own number, handling the questions your team answers over and over. I have built this before at scale: IASGuru, an assistant on the WhatsApp Business Cloud API and Telegram, served 10,000+ users and answered 2,000+ queries a day. WHO THIS IS FOR Your team answers the same twenty questions all day. Or leads message and nobody replies until Monday. Your customers are already on WhatsApp and will not install an app to talk to you. WHAT YOU GET • A live assistant on your own WhatsApp Business number (or a voice line), not a widget nobody clicks. • Grounded answers — it replies from your actual documents, FAQs, catalogue, or policies, not from whatever the model half-remembers. • Clean human handoff. When it is unsure, or the customer asks, the conversation moves to a real person with the full history attached. This is designed in, not bolted on. • Guardrails so it stays on topic and declines what it should not answer. • Your business systems connected — CRM, calendar, order lookup, or ticketing, so it can actually do things rather than just talk. • An analytics view: what people ask, what it answered, what it escalated, and where it is weak. • Full source code and deployment, yours to keep. COMMON BUILDS • Customer support and FAQ deflection • Lead qualification and routing • Appointment booking and reminders • Order and delivery status lookups • Internal helpdesk for your own staff HOW IT RUNS Week 1 — scope, knowledge base, and conversation design; you approve the flows. Week 2 — build and integrations. Week 3 — testing on real conversations, guardrail tuning, go live. You see working increments throughout, not one reveal at the end. WHY ME OpenAI contract engineer (agent evaluation infrastructure), founding engineer at three startups including Flasho (YC W20). Bot engineering across WhatsApp Business API, Telegram Bot API, and voice. More at https://pravaahtech.ai NOTE ON COSTS WhatsApp Business API conversation fees and model/API usage are billed by Meta and your AI provider directly — typically modest, and I will estimate them honestly for your volume before you commit. Message me with what your customers ask most and I will tell you what is realistic.

Requirements

To start, I need five things: 1. WHAT IT SHOULD HANDLE. Your top 20–30 real customer questions, ideally copied straight from WhatsApp, email, or your helpdesk. Real phrasing matters more than tidy phrasing. 2. THE SOURCE OF TRUTH. Whatever holds the answers — help docs, FAQs, a price list, policy PDFs, a product catalogue, or a link to your site. If it only lives in someone's head, a 45-minute call with them works too. 3. WHATSAPP BUSINESS ACCESS. A Meta Business account and a phone number not already registered to the regular WhatsApp app. If you do not have this yet, I will walk you through setup — it is the most common blocker, so flag it early. For a voice agent instead, tell me your telephony setup (Twilio, existing IVR, or nothing yet). 4. THE HANDOFF RULE. Who takes over when the bot escalates, and where they work — Slack, email, your helpdesk, or a shared WhatsApp inbox. Also: anything the bot must never answer on its own (refunds, medical, legal, pricing exceptions). 5. SYSTEMS TO CONNECT, if any. CRM, calendar, order database, ticketing — with API docs or credentials when we get to that step. HELPFUL: your brand tone (formal or casual), the languages your customers use, and rough monthly message volume so I can estimate running costs. Not sure about some of these? Message me anyway — the scoping call sorts it out.
