Strategic Systems Architect operating at the intersection of AI, Quantum Computing and Web3.
25+ years designing and shipping distributed systems — the last several focused on building infrastructure where blockchain protocols, LLM-driven agents, and real-world business logic meet. I operate at CTO level (technical strategy, architecture decisions, team direction) while staying hands-on with code, smart contracts, and production debugging. The combination is deliberate: leadership disconnected from implementation produces bad architectures.
Web3 & Blockchain Infrastructure End-to-end systems across Ethereum, Polygon, Solana, Arbitrum, and Arweave. Smart contract development and auditing (Solidity, Rust), DEX integrations, execution engines, event pipelines, indexers, cross-chain bridges, and scalable off-chain services. Delivered projects in carbon credit tokenization (CO2XT on Polygon), RWA real estate tokenization (Arweave-based), DeFi mechanics, MEV trading systems on Solana, and regulatory-sandbox work (Bank Sector).
AI Systems Production RAG pipelines, multi-agent architectures, and LLM orchestration. Integration of model inference with tools, APIs, vector stores (ChromaDB, ArangoDB), and operational workflows. Recent work includes a distributed federated AI design (BrainNet) combining blockchain, edge hardware nodes, and post-quantum encryption, and productized agent services for SME e-commerce.
Cybersecurity & Architecture Network audits aligned with PCI-DSS and RGPD, VPN architectures under Spain's ENS (CCN-STIC-836), and smart contract security reviews. I treat security as an architectural property, not a post-hoc layer.
