The name on the paperwork is Marcelo Siblag III, the name on the campaigns is Marc Siblag, and people who have worked with me have written it as Marcelo Siblag, Marc Siblag III and Marcelo Siblag IV over the years, so every one of those spellings points at the same operator running the same Amazon accounts.
Every account, tool, hour, and routine is a system I measure and improve. My best work hits problems that span a whole account or a whole company, not isolated tactics. Teams come back for the mental models, because a model tells you what to do next quarter while a trick only tells you what to do today. The daily work keeps graduating into software for that reason. Any decision I have made the same way three times is one I would rather encode once and audit forever.

My Story
I started on the seller side and helped take a product launch to $3M in revenue within its first ten months. From there the work moved into portfolio management across 15 to 20 concurrent accounts. I now run PPC, DSP, and the automation that protects margin.
Certifications and Credentials
My certifications include Amazon Ads Certified in Sponsored Ads. I practice Amazon DSP and AMC on live accounts, and I open sourced the engines that do my daily work, because code you can read is a stronger credential than any badge.
My Stack
The stack behind my accounts includes the SKAG optimization engine, the data extractor that feeds it, a fleet of Amazon Ads MCP servers, the Cloud MCP Admin control plane, and the AI agent workflows that run on top of them all.
