I'm a blockchain developer specialising in ZK development and smart contract 
engineering, with a focus on privacy protocols and DeFi infrastructure.

My primary direction is zero-knowledge engineering — writing Noir circuits, working with Barretenberg's UltraHonk proving system, and integrating on-chain Solidity verifiers. I'm drawn to the protocol layer: where cryptographic guarantees meet on-chain execution and the correctness bar is absolute.

On the smart contract side, I approach every build security-first — invariant and fuzz testing, CEI, ReentrancyGuard, and tight access control are defaults, not afterthoughts. I use Foundry exclusively and care deeply about test coverage that actually catches edge cases.

Currently advancing through Cyfrin's ZK curriculum, with a longer-term focus on ZK rollup ecosystems and privacy infrastructure.
