blockchain protocol engineer · consensys · backend & distributed systems

Hi. I'm Lucas. I work on Teku and the Ethereum protocol itself at Consensys. It's the kind of work where a single line of code can ripple across a global network of nodes, which keeps things interesting.

Over 10+ years of backend engineering I've developed a soft spot for systems architecture, high-scale distributed systems, and the particular thrill of shipping fast with a small team that actually knows each other's names. Mostly Java these days, with whatever else the problem demands. I've learned that the best tool is usually the one the team can debug at 2 a.m.

When I log off, I'm probably still staring at a screen, just with a controller in my hands instead of a keyboard. I'm working through a backlog of games that's grown faster than I can clear it.
