I will build a custom ai chatbot or whatsapp ai agent


About this gig
Losing leads because nobody replies fast enough? I build AI chatbots and WhatsApp agents that answer instantly, qualify leads and book appointments, 24/7.
Recent work: a bilingual (English/Spanish) WhatsApp AI consultant for a US med spa. It analyzes customer photos, generates AI previews, sends booking and financing links, and checks every reply against compliance rules (85 unit tests).
What I can build:
Website chatbots that answer from your own pages and documents
WhatsApp agents (Meta Cloud API, 360dialog, UltraMsg)
Booking, CRM and payment-link actions through tool calling
Hand-off to your team on the same number when needed
Guardrails so the bot never promises prices or things you don't offer
You get:
A bot trained on your business, in your tone
A test run on real customer questions before launch
Source code and setup instructions
Stack: OpenAI, Claude, TypeScript, Python, pgvector, Supabase.
Message me with your business and the channel you want (website, WhatsApp or both), and I'll suggest the right package.

FAQ
Can the bot use my existing WhatsApp number?
Yes, through the WhatsApp Business API, and your staff can keep replying on the same number.
Does it work in other languages?
Yes. I've shipped English and Spanish bots, and most major languages work well.
Can it book appointments?
Yes. It can send booking links or create bookings through your calendar or booking tool's API.
Who pays for WhatsApp and AI usage?
You do, on your own accounts. I'll estimate the monthly cost before we start.
What if a customer asks something the bot can't answer?
It hands the conversation to your team instead of guessing.
