FAQ
Do you deploy on MY server or yours?
On YOUR server, always. I deploy using Docker + Traefik on your VPS with automatic SSL. If you don't have a VPS yet, I can set one up for you in about 2 hours on Hostinger (~$5/month). You own everything — full source code and infrastructure.
What can you automate with n8n?
Almost any repetitive business process: WhatsApp lead qualification, automated follow-ups, daily reports via Telegram or Slack, CRM integrations, Google Sheets sync, appointment scheduling, data enrichment, email sequences, and API integrations. Message me with your use case.
Do you provide ongoing support after delivery?
Yes. Starter includes 3 days of support, Pro includes 7 days, and Full Bot includes 30 days. I keep working until your workflow runs perfectly. After the support period, I offer maintenance packages if needed.
