I am a self-taught developer with over 10 years of experience in both back-end and front-end development. I enjoy turning complex requirements into clean, scalable software and continuously refining my skills through hands-on projects and in-depth exploration of official documentation. I value documentation as a powerful teacher, helping me understand core concepts, troubleshoot issues, and stay up-to-date with the latest technologies and best practices. I have extensive experience building RESTful APIs and web services, integrating custom pages and payments, and leading CI/CD pipelines with tools like Jenkins and Azure DevOps. My work spans Vue.js, Ruby on Rails, React, and PHP in Scrum-driven environments, delivering robust solutions for clients in the US and Latin America.
