Hello there!

I'm Fabián Sánchez.

Full-Stack Developer (Web3)

I'm an 18 year old Computer Science (Ing. Sistemas) student at TEC, Costa Rica! I really enjoy programming, open-source contributing and I have created projects with multiple technologies and stacks.

Also, I am interested in multiple fields such as web3 (blockchain, smart contracts, etc.) and AI. One of my core skills is communication.

We suffer more in imagination than in reality. - Seneca
