About me
The person behind the code
I’m Ghaniyyir Rahman Sudarsono, an IT student and backend-oriented full-stack web developer.
I focus on building web applications with structured databases, clean API flows, authentication, validation, and practical application logic. My current stack includes Next.js, TypeScript, React, Prisma, PostgreSQL, Supabase, and Node.js.
I enjoy understanding how systems work behind the scenes, especially how data moves between the client, server, database, and business logic. My goal is to keep improving as a developer who can build reliable, maintainable, and useful web applications.
Technical Focus
I value building practical, maintainable, and useful applications. My focus centers on secure backend flows, relational database structures, clean APIs, input validation, and full-stack integration over purely presentational logic.
