I will build ai automation workflows with n8n, whatsapp bots and apis


About this gig
Tired of copying data between apps, answering the same WhatsApp questions all day or chasing leads by hand? I build automations that do this work for you.
I co-founded and develop a SaaS for affiliate marketers that runs in production with 438 customers and publishes about 8,000 offers per day to WhatsApp and Telegram, fully automated. I also work as a backend developer on an EdTech platform, building payment and enrollment automations with webhooks and n8n.
What I can build for you:
- n8n workflows connecting your apps, forms, CRM, spreadsheets and payment platforms
- WhatsApp and web chatbots with AI (GPT or Claude) that answer, qualify and register leads
- AI agents that read your data and send alerts, summaries and follow-ups
- Custom API integrations and webhooks in Python, Node.js, Java or C#
How it works:
1. Send me your process and the tools you use
2. I reply with a fixed scope and timeline
3. I deliver in steps you can test, with documentation
Please message me before ordering so I can confirm the scope.

FAQ
Do I need to pay for n8n or other tools?
n8n can run on n8n Cloud or self-hosted on a small server. I help you pick the cheapest option for your volume. Tool subscriptions are paid directly by you, in your own accounts.
How do you connect WhatsApp?
Through the official WhatsApp Business API or the provider you already use. Before starting, I recommend the safest option for your message volume.
Will I own the workflows and the code?
Yes. You get the workflows, source code and documentation, all set up in your own accounts.
