Architecting the Future with 30+ Years of Systems Integrity.

With over 31 years of experience in mission-critical software engineering, I bridge the gap between institutional-grade stability and the decentralized future. My journey spans from the early days of Visual Basic and Java to leading complex digital transformations for National Customs (DNIT) and major financial institutions like Itaú Bank.

Currently, I am a Senior Staff Blockchain Architect specialized in building secure, high-performance infrastructure. My "unfair advantage" is a deep expertise in PKI (Public Key Infrastructure) and HSM (Hardware Security Modules)—the foundation of institutional crypto custody—combined with a modern stack in Rust (Solana/Anchor) and Node.js (EVM/Wagmi).

What I’ve Done:

• Designed and deployed high-availability systems for government tax and customs (99.9% uptime).
• Led banking-grade migrations and security integrations for hardware-level cryptography.
• Architected dApps and smart contracts on both Solana and EVM ecosystems.

What I’m Looking For:
I am seeking Staff/Principal Architect or Technical Lead roles in companies that demand absolute reliability and security. I am particularly interested in Web3 Infrastructure, Institutional Custody, and RWA (Real World Assets) Tokenization projects where I can apply my decades of experience to ensure architectural excellence
