> Since 2019, I have dedicated my career exclusively to the world of blockchain technology— a passion that has guided both my professional and personal development, and one I hope will continue to do so for many years to come. I strive to stay up to date in the fast-paced Web3 ecosystem while also pursuing independent projects. My skills range from technical conceptualization to the actual implementation of solutions, accurately interpreting the client’s often nebulous ideas. Not everything has to be blockchain—I aim to be pragmatic with technology, applying it where it makes sense, and leveraging existing off-chain technologies to improve project efficiency. I don’t focus solely on smart contracts, but also on accessibility, user experience (UX/UI), tokenomics, cybersecurity, and, more broadly, on the entire cosmogony of a Web3 project.

UI . UX

Web3, fullstack experience

We eat with our eyes, and even more so in the crypto world.

I have created full-stack web designs to guarantee the best user experience. I have experience integrating all types of wallets. I also design in Flutter for the creation of wallets for mobile devices.

2025

Capicrypto - Side project of palindromic cryptographic curve

see my portfolio

I have carried out a side project to create my own cryptographic curve for a better understanding of its mathematics. It has no real use, but it is a good way to understand the nature of these objects.

2025 . present

Creation of Hyperledger Besu QBFT networks.

Permissioned networks with K1 and R1 curves.

The R1 cryptographic curve network was created to align with European government regulations.

CTO and more...

With Otium, I learned how to manage teams and face difficult decisions with limited information.

Project management

I expanded my knowledge of classical economics for successful tokenomic development.
