Blockchain Developer · InfoSec Professional · Open-Source & Product Builder

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 DeFi protocols, mobile dApps, developer tooling and injection frameworks - and I design and ship full-stack AI products end to end. I hold a postgraduate-equivalent certification in Cybersecurity & Data Protection (DPO / GDPR), bridging the technical and compliance sides of modern software.
I like going deep: investigating how things work, taking them apart, and building things that hold up. Currently focused on blockchain developer tooling, autonomous AI agent systems, and cross-chain infrastructure.
💼 Available for development. Most products showcased here are working prototypes - the complete product, including the private production backend, can be built and delivered for you under a development agreement. Get in touch on X / Twitter.
