AWS Solutions Architect · Golden Jacket holder · ~15 years in cloud.

I write Golden Jacket Field Notes, a weekly practitioner series on production ML, GenAI, and cloud architecture. Not re:Invent recaps. Not tutorials. Field notes from workloads where outages, audit gaps, and cost surprises are not tolerated.

I co-founded Golden Jackets Brazil, the community connecting every Brazilian who has earned this status.

• golden-jacket-field-notes — index of the weekly series, with links to published articles and companion code
• Companion repositories for selected Field Notes — reference architectures, working examples, and reproducible setups

Not every article gets a companion repo. I only publish code I have actually run and can defend in issues.
