I'm Sidney. I build onchain systems and decentralized applications end to end — protocol-level design, full-stack architecture, and security-focused engineering. The focus is always the same: how it's built matters as much as what it does.
Blockchain Development Full-stack blockchain engineering, end to end. I design and build decentralized applications across Solana and EVM chains architecture, protocol integration, frontend, and everything that connects them. I think in systems, not isolated features.
AI & Model Security I build production systems powered by large language models and study how they fail. My focus is on model reliability and security how these systems hold up under adversarial pressure, and how to engineer around the failure modes, not just around the demo working.
Technical Research I'm exploring the frontier of decentralized systems: DeSci, DePIN, decentralized AI infrastructure, and incentive design how these fields intersect with security. This is active research, not a side interest.
I write about Web3, AI security, and decentralized systems on Substack. Read my latest article →
Open to contracts, technical roles in Web3, and research collaborations. If it's real work, I'm interested.
