Nadina (Oates) Zweifel

Blockchain & Web3 Developer

I build to transform the future.

What do Neuroscience, AI, and Blockchain have in common? These are fields that are constantly evolving and might change the world in significant ways - some believe for the better, others for the worse. The potential and controversy of these fields have always fascinated me and stimulated my curiosity to learn more about them.

Currently, I am a Fullstack Blockchain Developer based in Chicago. I have over 3 years of experience inCrypto, NFTs, DeFi, and Web 3.0. I've led projects from concept to production, developed NFT minting dapps, and my latest achievement was a cross-chain nft collection minted from BNB chain to Base chain. My skills span TypeScript, Node.js, React/Next.js, TailwindCSS, Wagmi/Viem, Solidity, Hardhat, Foundry, and Slither.

My versatile skill set extends beyond web and blockchain development to data analysis and computational research, where I've managed projects, released novel simulation software, published impactful journal articles, and received a research progress award at Northwestern University. I also have industry experience working on machine learning and deep learning projects using Python - PyTorch, Scikit-Learn, and AWS Cloud Services.

In addition to my professional work, I'm dedicated to promoting Web3 adoption. I co-founded multiple web3 communities and host crypto community events in Chicago. I am excited about the potential of blockchain and decentralized technologies and am committed to bringing Web3 adoption to the masses. If you're looking for a versatile developer who can take your projects to the next level, let's connect and discuss how I can contribute to your team.
