About the Position

Introduction

I'm Andrei Zolin, a Senior Solidity Developer with over six years of experience in blockchain development and more than eight years in IT. I specialize in building secure and high-performance smart contracts, having worked on DeFi, stablecoins, and cross-chain solutions, with over $10M secured on-chain. My passion lies in designing decentralized financial systems that are both scalable and secure, and I enjoy tackling complex challenges in smart contract security and optimization. I'm also experimenting with building AI agents using the ElizaOS and Virtuals frameworks and optimistically exploring this emerging movement.

Beyond my work, I’m deeply involved in the crypto space, engaging with the community, researching new blockchain trends, and exploring innovative DeFi mechanisms. I also run a community of Solidity developers on Telegram, where we discuss best practices and cutting-edge developments in smart contract engineering.

Outside of blockchain, I stay active by playing padel, cycling, and running. I also enjoy reading thought-provoking literature, especially works by Viktor Pelevin. Currently, I’m based in Buenos Aires and always open to connecting with like-minded professionals in the Web3 space.
