Mine, plant, port, railway, office. Connectivity is a floor-of-operation requirement, not a luxury.

Enterprise applications
SAP, Concur, LeanIX, ServiceNow and 1000+ systems speaking through the same network spine.
II.Thesis
I'm an operator-builder. The notebook is the same one I carry from the desk, to the mine floor, to the Tuesday of week seven.
Enterprise architecture, telecom and agents in production. I design the thing, operate the thing, keep the thing alive. I prefer systems that have already run sixty days straight to ones that dazzle in a demo and vanish next sprint.
III.Selected systems · named work
Four systems, real-world scale.
2020–nowPrivate LTE
Private LTE spine · Vale
One of Brazil's largest private LTE networks · mine, railway, port.
Radio coverage engineered for open-pit mine, freight rail and industrial plant. Real handover between operational sectors, dispatch system integration, critical radios, M2M at scale.
Enterprise traffic crossing borders through tunnels designed for the application, not the topology. End-to-end observability. SAP answers in Vitória with the same latency it had at the office.

2024–nowAgentic layer
Agentic layer · SAP · Concur · LeanIX
Agents submitting real work · human in the loop.
Not a chatbot that replies. A routine that fills the form, dispatches the approval, fetches the attachment, returns the status. Does the work an Enterprise Architect skips out of fatigue or lack of coffee.

2025–nowAgent in the wild
GoJoana · agent in the wild
60+ days of continuous execution · operated out of Vitória.
AI secretary on WhatsApp. Runs unattended — contact triage, scheduling, work submitted to SAP/Concur. Proof that an agent in production isn't a demo, it's a run.

IV.Trajectory · 21+ years of practice
Six chapters, one notebook.
Today
Vale · Enterprise Solutions Architect
~50k devices · ~75k users · 1000+ applications · 3 continents. I design and operate networks, telecom, critical connectivity and the agentic layer. I lead the Vale infrastructure laboratory at IPT in São Paulo since 2022.
International deployment
Oman · Middle East
Vale's pelletizing plant in Oman. Design, procurement and field installation of networks, telephony and servers. Civil works, site survey, the cable that arrives before the rain.
Earlier years
HP · HPE · Network & Enterprise Architect
Multinational practice in enterprise networking, datacenter and managed services. Carrier grade, global scope.
Earlier years
Orange · Network engineering
Carrier networks, international WAN, corporate IT. Operator vocabulary picked up early.
Career start
Dix Amico · Amil group · programming intern
One year writing production code as an intern. Where I learned that code that runs carries a different weight than an exercise that closes on paper.
Education
PUC-Rio · Computer Science
Fundamentals · carioca by training, Vitória by operation today.
V.Firsts · Brazilian milestones
Firsts in Brazilian mining.
Not a catalogue. Every brick below went through field, budget, homologation, and still runs today with people depending on it.
I.
Private LTE
Brazil's first private LTE network in mining
Co-created with colleagues. Critical radio, handover, M2M at mine scale. Left the page, became routine operation.
ValeLTEMining
II.
Private 5G
First private 5G network in Brazilian mining
Design, homologation, architecture. Next-gen radio in the same plant where LTE had just proven the thesis.
Vale5GMining
III.
Starlink fleet
80+ vehicles connected with Starlink
LEO constellation on a mining fleet. Stable latency where fibre won't reach and the tower charges dearly.
LEOStarlinkFleet
IV.
Vale lab · IPT-SP
Vale infrastructure laboratory at IPT, São Paulo
Coordinated since 2022 · telecom, hosting, AI, robotics, EUC/EUX. Where architecture becomes a workbench before becoming a budget.
Hawaiian canoe on the morning waters of Vitória bay — the closest discipline I've found to writing code in silence.
PlayStation 5
Other worlds, other engineerings. Building and breaking systems is still leisure, only on different orbits.
Joana & Menina
Two cats, silent co-authors. Joana lent her name to the agent — and still reviews every commit from the couch.
Oman, and the rest of the map
Lived and worked in Oman; then Europe, Africa, and both Americas. Landscapes that keep shaping how I read networks.
VIII.Contact
The Tuesday of week seven. That's when the real system shows up.
If what you're building has to run unattended in production — on critical networks, in mining, on agents living 60 days without falling over — let's talk.
