★★★★★
"No jargon, no upsells, just a setup that works. The AI handles repeat questions and our team finally focuses on real customers."

FAQ
Common questions before you hire
How much does it cost?
It depends on what you want to automate — a single chatbot is very different from a full multi-tool setup. After a free 1:1 on Upwork, I send a written scope and a clear fixed quote. No surprises, no hourly ambiguity.
How long does it take to set up?
Most chatbots and follow-up flows go live in a few days to two weeks, depending on complexity and integrations. A full marketing-ops overhaul is usually 4–6 weeks. All milestones are baked into the Upwork contract.
Do I need any technical knowledge?
None at all. I handle the strategy, build, testing, and deployment, then train your team so it's simple to run day to day. You own everything I build.
Which platforms and tools do you support?
WhatsApp, websites, Instagram, plus CRMs, Google Sheets, payment gateways, n8n, and almost any tool with an API. If it connects, it can usually be automated.
What if it doesn't work for my business?
That's exactly what the free 1:1 is for. I'll tell you honestly whether automation fits your situation — if it won't help, I'll say so. No fluff, no upsells.
