I'm here as

Customers slip through the gaps between your ads, your website, and your follow-up. I connect the three, so attention turns into conversations your team can act on.

Behind the system

I'm Rangga. I connect the parts.

I've worked as a Digital Growth Specialist in Jakarta since 2022, across campaigns, websites, content, lead handling, reporting, and automation.

The work I like most is where marketing, the website, and sales follow-up finally share the same context, and the team can keep running it after I hand it over.
