About

Eternal Spring is a blog where I explore ideas in mathematics, cryptography, and martial arts.

I’m Stefano, a software engineer based in Berlin with a focus on distributed systems and cryptography. I enjoy building clean, maintainable, and secure systems that make people’s lives better.

In my career, I contributed to the development of multiple components of a blockchain system. At Noble I helped shape the infrastructure for cross-border payments. I’ve contributed to a stablecoin automated market maker (AMM) based on the stableswap invariant, and designed an abstraction layer for automated cross-chain routing on top of the Inter-Blockchain Communication (IBC) protocol, the Circle Cross-Chain Transfer Protocol (CCTP), and Hyperlane. Before this experience, I helped Altiplanic support the Ethereum Virtual Machine (EVM) in systems based on the Cosmos SDK.

Products I worked on facilitated over $100M in stablecoin transfers and $1B in exchanged volumes.

Before developing my passion for computers and finance, I did research at the intersection of machine-learning and aerospace structural analysis. I was fascinated by instability phenomena in cylindrical shapes, and how to efficiently optimize them without solving complex non-linear equations. I spent around 1 year during my PhD implementing feed-forward neural nets combined with bio-inspired optimization algorithms.

Work stuff aside, I love martial arts. I practiced Judo for around 13 years, and I’m now a second-dan black belt. When I was 18, I placed 3rd at the Italian championships. If you’ve never tried judo, I strongly recommend it! From Japan to China, I recently started studying Kung Fu, specifically the Wing Chun lineage from Leung Ting.
