I'm a Founding Engineer at Maze, following senior engineering roles at Monad and Meta, where I worked on infrastructure software, systems design, and production engineering.

Over more than 20 years, I've built and operated software, cloud, network, and data infrastructure across Python, Go, Linux, containers, PostgreSQL, and MySQL. At Instituto Igarapé, I developed the webrecorder Android library to record MP4 video while streaming H.264 frames through WebSockets for the Smart Policing project.

I've also led scientific and public-interest technology work, from petabyte-scale data platforms at LIneA to distributed workflows, high-performance data transfer, GIS, and remote browser-control tools. I bring hands-on experience spanning software development, systems administration, databases, networking, and technical consulting.
