About Myself

I’m a full-stack developer focused on building practical software that improves how teams operate. I’ve worked on real-world systems involving APIs, dashboards, and data workflows—helping turn manual processes into efficient, automated solutions. My background isn’t traditional. I taught myself English to access global opportunities, worked remotely in high-pressure environments, and developed strong problem-solving skills along the way. That experience shaped how I approach software: with resilience, adaptability, and a focus on delivering results. Today, I specialize in Ruby on Rails, JavaScript, and modern web technologies to build scalable backend systems and clean, usable interfaces. I care less about trends and more about creating software that actually works in production and solves real problems. Fun fact: I grew up thinking everyone spoke the same language—turns out, learning a new one opened the door to my entire career.
