I build web and mobile applications, with a focus on useful products, clean interfaces, and end-to-end development.

Currently working with TypeScript, React Native, Next.js, Supabase, and modern web technologies. I enjoy turning ideas into complete applications: from UI and authentication to database design, APIs, and deployment.

• Building full-stack web and mobile applications
• Improving my skills in TypeScript, React Native, Next.js, and SQL
• Creating projects with authentication, databases, real-time features, and responsive design
• Learning more about software architecture, backend development, and deployment workflows
