What I'm looking for

I'm looking to build secure, production-grade blockchain and fintech products, especially payments, wallets, smart contracts, and full-stack Web3 infrastructure.

I've built blockchain payment, wallet, and smart contract products at Nahmii AS, RampHub, and Paychain. At RampHub, I helped build a crypto on/off-ramp aggregator processing over $200K in volume across 150 customers and seven businesses.

At Nahmii AS, I wrote and tested Solidity contracts and delivered full-stack applications for Ethereum Layer 2 infrastructure, including orderbook infrastructure for a central bank digital asset initiative and NFT-based Web3 games with provably fair Chainlink VRF mechanics.

I work across React, Next.js, TypeScript, Node.js, PostgreSQL, Solidity, and cloud deployments, and I enjoy connecting on-chain systems to reliable customer-facing financial applications.
