Background

Before this

I started as a Java backend engineer in 2007 — enterprise systems, e-commerce, social apps — and slowly built up real distributed-systems chops. A few years later I rode the mobile-internet wave: leading a payment system that served a million merchants, then routing algorithms for a food-delivery platform at peak hours.

From 2020 I went independent and shipped whole products solo. In 2022 I moved into Web3 properly — DeFi architecture, contract audits, the whole frontend stack. The last two years my attention has shifted entirely to LLMs and agents.
