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.
