a·ru·ei·ra, n. — folk form of aroeira, a Brazilian hardwood tree known for withstanding time.

I turn scientific complexity into competitive advantage.

As CTO and co-founder of LRGE Systems, I bring artificial intelligence inside companies’ own infrastructure — at lower cost, lower risk, and with full control over the data.

Focus

  • Sovereign AI & model distillation
  • Offensive security & digital forensics
  • High-performance computing

Track record

Think like an attacker to build what endures.

From nanosatellite software to leading engineering at an AI company — with the same method since day one.

2014 — 2016

14-BISat nanosatellite software

Instituto Federal Fluminense

During the Informatics technical program at IFF, I worked on developing and testing the software for 14-BISat, the institute’s nanosatellite — published in IFAC-PapersOnLine (Elsevier).

Until 2024

Offensive security research

Built OSINT and threat-intelligence tooling. That is where the method began: understand the attack to engineer the defense.

2024 — now

CTO & Co-founder

LRGE Systems

I lead engineering across AI, patented facial biometrics and high-performance computing for public and private clients in Brazil and abroad.

2025 — now

Professional M.Sc.

Instituto Federal Fluminense

In Applied Systems for Engineering and Management (SAEG), advised by Prof. Rogério Atem de Carvalho. Academic research grounds the industry work: working is not enough, it has to be provable, measurable and well-founded.

Delivered results

−92%
AI operating cost

Model distillation plus a proprietary ontological layer: from 20 GB down to 1.5 GB, with the semantic quality of 20B+ models.

8 TB/day
Evidence processed

Automated digital forensics: time-to-evidence drops from months to hours in complex litigation.

−97%
Data volume

High-entropy compression turns petabytes of raw data into manageable assets, at a fraction of the hardware cost.

100%
Audit traceability

An immutable ledger (XRP) traces transactions in real time and removes compliance risk.

Publications

Applied, peer-reviewed research.

From software engineering for nanosatellites to artificial intelligence regulation in Brazil.
