Uberlândia, Brazil

The part of the network
nobody sees, written down.

Most people pick a layer and stay there. I never managed to. The day job runs from mobile networks and IoT platforms, all the way up to the roadmaps, business cases, and budgets that make them viable. The notes here come from the whole range, hobbies included.

Mobile core · Kubernetes · Diameter · Solution Architecture · IoT / M2M · MQTT · Kafka · Linux · AWS · homelab · LLM agents · ESP32 · and whatever I'm taking apart this month

Field Notes.

Meu Agente IA No K3s Com Openclaw

Do Docker Compose para o K3s: o manifesto, o openclaw.json e as decisões que fazem diferença no dia a dia — contexto sem perda, consolidação de memória noturna, failover de modelo e as políticas de limite que ninguém configura.

02 Open

What I'm working through.

Open questions, not conclusions. If you have the fix, I'm all ears.

04 Contact

Ask me something.

If you're stuck on Telco, Cloud, or an IoT platform that stopped behaving, write to me. I answer questions from strangers—it's usually how the next post starts.

If you need a deep dive, an architecture review, or dedicated consulting, let's talk business.
