I'm Martín, a Principal Engineer and software architect based in Mar del Plata, Argentina.\nI've been designing backend, cloud and IoT systems for over 14 years, and what I enjoy most\nis finding the simplest architecture that solves a hard problem.
\nI've spent much of my career in media and entertainment, building video pipelines for WWE\nand Canela Media that bring content to platforms like WWE Network, YouTube, Peacock and\nBrightcove. Before that I worked in fintech, on Tigo Money across several Latin American\ncountries. Today I'm also building Armadillo Gaming, modular gaming tables with IoT and AI.
\nI work with spec-driven development and AI agents, and I teach Software Engineering at\nIDRA, where I mentor students through projects for real clients.
\nTo see what I've worked on, try ls projects or cv. To reach me, contact.
LinkedIn is the preferred way: send me a message about what you need.
