About Me

Many years ago, I was at the same point that you may be now: fascinated at new technology, but lacking sufficient understanding to make my ideas a reality.

I'm a freaking expert in banking systems and financial institutions, the real deal, with 43 years of experience, deep experience in both legacy and the most modern systems, team leadership, teaching, project management, taking real projects from 0 to 1.

I care about these metrics:

  • • user satisfaction
  • • scalability
  • • availability

I am now trying to take a million people into the future.
As I think the future should include us all.

Bio

I started collecting punched cards from the street in 1970, from a nearby computing center. In 1975 I became a gamer. In 1980, under military dictatorship, I became a composer and helped bring the punk movement to South America. In 1983 I started programming in BASIC and Assembly languages. I switched to IBM systems in 1987. Then to the Internet in 1997, and to Java in 1998. Then to Linux in 2002. In 2004 I started experimenting with Machine Learning using Scheme (a Lisp dialect). In 2013 I started working with Bitcoin and Python, helping create the Bitcoin community in South America. In 2017 I switched to Ethereum, and in 2023 to Solana. Since 2021 I have been teaching and working on AI.

Author of "Introduction to Blockchain and Ethereum" (Packt Publishing - London) — a comprehensive guide to distributed ledger technology, smart contracts, and decentralized application development.
