I'm Esteban Soto, a Senior Backend Engineer with 14+ years specializing in Ruby on Rails API development and payment system integrations. Proven track record of migrating monoliths to microservices, managing tech debt, and building scalable billing solutions. Expert in designing robust backend architectures and improving developer productivity through internal tooling.
Beyond code, I'm a proud father of two. When I'm not building software, you'll find me perfecting my pour-over technique or pulling shots on my Breville espresso machine — coffee is serious business. I'm a continuous learner, and my latest obsession is AI — specifically building personal workflows with Claude to be more productive. Gaming is my way to unwind: I play Nintendo Switch with my youngest, my oldest is on the PC Master Race path, and I'm a PlayStation guy at heart, currently exploring the world of Death Stranding on PS5.
