AI Enthusiast

Who am I?

Picture of me

I am Sebastian Zambrano Arango, I have always been very curious and an enthusiast about technology. That lead me to discover Blockchain on 2021 and since then start learning about how the technology works, and as I loved it's capabilities and functionalities, I decided I will dedicate to it.

With an school background of C language, I started learning Solidity on my own with all the resources that there are out there, completed several courses and realized I needed to learn more than Solidity if I wanted to dedicate to it, it was there when I learned about security and optimization in Solidity and more Languages and tools for being a Web3 Fullstack Developer such as Javascript and React with NextJs. And for testing all what I have learned I am building a protocol on my own which is in it's MVP phase right now.

Lately I have been paying attention to AIs and figuring out how to use them in my daily study and coding sessions to improve my efficiency.

Working with different clients has allowed me to both improve my skills, adapting myself and learning depending on their needs and requirements, and also to improve my communication skills and candidness.

Having worked from building projects from scratch with no team to teach someone how to code his first Smart Contract, leaving all the basis and resources to follow the study, has given me a solid basis to every project.
