Hi, I'm Francisco Costa 👋

I'm a software developer with a strong background in blockchain infrastructure, InfoSec, and full-stack engineering. I specialize in the Solana and Sui ecosystems, building open-source tooling, injection frameworks, DeFi protocols, and mobile dApps. I hold a postgraduate-equivalent certification in Cybersecurity & Data Protection (DPO / GDPR), bridging the technical and compliance sides of modern software.

I love going deep — investigating how things work, breaking them, and building things that break things. Currently focused on blockchain developer tooling, autonomous AI agent systems, and cross-chain infrastructure.
