Back to original languageAbout Yannis
Developer for over 2 years, with training at École 42,
I am a Fullstack Javascript developer with expertise in Web3, NFTs, and the Ethereum blockchain (Solidity).
I am also interested in the Tezos blockchain and the Elrond blockchain (Rust) and wish to improve my skills in Typescript and NestJS.
I recently participated in the creation of a platform for purchasing physical art certified by NFT on the Ethereum blockchain.
Passionate about blockchain and convinced that this technology will be the engine of our near future, I have decided to make a career in this sector.
