Marvy Nwaokobia

Full-stack & protocol engineer. I build secure systems end-to-end — smart contracts, cryptography, backends, and the apps on top of them.

I work across the stack: designing on-chain protocols and the cryptographic primitives underneath them, writing the backend services that support them, and building the frontends people actually use. I care most about correctness and security in systems handling money, identity, or private data.

What I work with

Languages — Solidity, Rust, TypeScript, Python, Cairo

Smart contracts & protocols — EVM (Solidity), Soroban (Rust/Stellar), Cairo (Starknet)

Cryptography — zero-knowledge proofs (Circom, Groth16), fully homomorphic encryption (Zama FHEVM), Merkle trees, secret sharing, commitment schemes

Full-stack — Next.js, React, Node.js, PostgreSQL

Data — Python, pandas, Jupyter
