What I'm looking for

I’m seeking strategic positions in R&D, Risk, or Technological Innovation, where I can translate NISQ-era scientific experimentation into corporate solutions that ensure security, efficiency, and scalability.

At Itaú Institute of Sciences and Technologies – UFF, I research quantum cryptanalysis for critical financial infrastructure. I study and implement Shor’s algorithm for the Elliptic Curve Discrete Logarithm Problem, evaluating cryptographic impacts under NISQ-era noise to inform Post-Quantum Cryptography adoption.

At Petrobras – UFF, I developed Digital Twin software for intelligent completion systems in energy exploration. I also created technical documentation and software architecture diagrams to support maintainability and scalability.

My research at Universidade Federal Fluminense included reviewing literature and producing scientific papers on quantum algorithms. For my thesis, I studied quantum algorithms for the Quadratic Binary Equations Problem; my MSc dissertation evaluates exact, heuristic, and quantum approaches in the NISQ era.

I’ve also worked on backend applications and Docker containerization for a Condition-Based Maintenance system for Blowout Preventers. At Universidade Federal Fluminense, I supported digital circuits classes and laboratory work, and I received first place at LACLO in 2025 for an educational card game teaching numerical systems and computational logic.
