Andrei Lopes

Solution Architect and technology leader with experience spanning industrial process structuring, software engineering, enterprise architecture, pre-sales, people leadership, and scalable platform design. Started with a strong Production Engineering foundation focused on efficiency, process standardization, quality, and continuous improvement, and evolved into backend development, distributed systems, cloud, API-led integration, and architecture governance. Experienced in translating business needs into technical roadmaps, technical specifications, proof-of-concepts, and scalable solution designs across banking, insurance, consulting, and digital transformation environments.

Hands-on background in Java, Spring Boot, APIs, cloud modernization, CI/CD, and system integration, combined with consultative engagement in pre-sales, stakeholder alignment, team structuring, and partner ecosystem development. Intentionally expanding into Ethereum/EVM with flagship PoC VaultGuard RWA, a permissioned tokenization and compliance stack with Solidity/Foundry, Spring Boot BFF for KYC/AML off-chain with hashes on-chain, and Next.js investor/issuer experience on Vercel, maintaining the same obsession as in core banking: clear on-chain vs off-chain boundaries, auditability, and no raw PII on the ledger.
