Full Stack Software Developer | Web & App Development
Barcelona, Spain - 12:13 am local time
I work across the entire stack — from designing clean, responsive front-ends with React and Angular to building robust back-end systems with Node.js and Python, managing databases like PostgreSQL, MySQL, MongoDB. Whether you need a full application built from scratch, an existing project improved, or bugs fixed fast, I focus on writing clean, maintainable code and delivering on time.
I'm detail-oriented, communicate clearly throughout the project, and treat every client's business goals as my own. I'm currently building my portfolio on Upwork and bring the same dedication and quality to every project — big or small.
Let's talk about what you're building. I'd love to help bring it to life.
