About

Estéban Reynier

Intro

Freelance Full Stack Solidity developer based near Lyon, France.

After 4 years at Ecole 42, I began immersing myself in blockchain and web3 technologies in 2021, specializing in Ethereum, EVM-compatible chains with Solidity.

I'm passionate about the potential of blockchain and decentralized technologies and I'm always looking for new opportunities to contribute to meaningful projects. Even when I'm not working for clients, I'm always looking for new things to learn in various domains.

My goal is to help you achieve your goals. I use my skills in Solidity and Web3 to create customized blockchain solutions that meet your needs.
