Full Stack Developer

I build scalable web applications and cross-platform solutions using modern technologies. Focused on clean code, performance, and user experience.

// About Me

I'm a Full Stack Developer with nearly 4 years of experience building web applications and cross-platform solutions. I specialize in both frontend and backend development, which means I can handle every aspect of your project - from user interface to server infrastructure.

I work primarily with modern technologies like JavaScript/TypeScript, React, Node.js, and Elixir. I also build cross-platform desktop applications using Tauri and have experience with Phoenix LiveView for real-time web apps.

I follow best practices in software development and pay special attention to accessibility, performance, and maintainability. My goal is to write clean, testable code that solves real problems.
