What I'm looking for

I'm open to roles, internships, training programs, and collaborative team opportunities where I can keep growing and contribute to impactful projects.

I'm building full-stack web and mobile experiences at DOANDGO, where I redesigned the mobile interface from Figma to Flutter with light and dark modes.

During my DOANDGO internship, I validated and optimized a Node.js API with automated tests achieving 98.2% success, introduced Redis in production, and delivered a React.js Middle Office dashboard with data visualization.

As a freelance web and mobile developer, I've taken responsive client applications from UI/UX integration in Figma through REST APIs, secure authentication, and deployment. I also built AIRSEN with Java Spring Boot and Angular and developed a Node.js and MariaDB REST API documented with Swagger.
