About Ramzi

You use multiple tools that don't talk to each other. You manually re-enter information, manually follow up, and copy-paste between Notion, Gmail, and your billing system.

I connect your tools so it happens automatically.

Using no-code if it's sufficient: Make, n8n, Zapier.
Using code if the need requires it: Spring Boot, REST APIs, webhooks.

Unlike most no-code freelancers, I can go all the way to the backend. No technical limits, no dependency on a single tool.

What I do concretely:
— Automatic client onboarding (form → CRM → email → billing)
— Payment reminders without intervention
— Synchronization between your existing tools
— Automated reporting
— Custom API integrations

No migration. No new tool to learn.
I work with what you already have.

Response time: 24h. Start: within 1 week.
