I will build an ai assistant for whatsapp or your web app
Carlos Z
About this gig
Your customers ask the same questions all day. An AI assistant can answer them instantly, 24/7, using your own business information, and hand the conversation to a person when it matters.
We're ZMDevs, a senior product team from Argentina working on US hours. We built Aldo AI, an AI sales assistant for WhatsApp, and we build web and mobile products end to end.
What you get:
- An assistant that answers with YOUR data (products, prices, policies, FAQs)
- WhatsApp Business or website chat (or both)
- Handoff to a human when needed
- Built on OpenAI or Claude, chosen for your use case and budget
- Clean, documented code that you own
Not included: WhatsApp Business API and AI usage fees (paid directly by you, usually low), and anything outside the package. Bigger scope? Message me for a custom offer.
Message me before ordering so we can confirm it fits your case.

Software engineer with 9+ years building web and mobile products. I lead a small team in Argentina that designs, builds and maintains them end to end: 20+ projects for clients in 3 countries, including a security product in Australia and an e-learning platform in the UK.
I take on MVPs and web apps (React, Next.js, Node, PostgreSQL), iOS and Android apps (React Native, Flutter) and discovery work to scope an idea before building it.
You talk to me directly, see progress every week and own all the code.

FAQ
How much does the AI cost per month?
It depends on volume. For most small businesses it's a few dollars a month, paid directly to OpenAI or Anthropic. We help you estimate it before we start.
Do I need the WhatsApp Business API?
Yes, for the Standard and Premium packages. If you don't have it yet, we help you set it up.
Can the assistant make mistakes?
It can. That's why we limit it to your own information and set it up to hand the conversation to a person when it isn't sure.
