I build modern web applications, backend services and developer tools that are fast, maintainable and preferably powered by Bun.
- 🎂 I'm an 18-year-old software developer from Germany.
- ⚡ My main language is TypeScript, while I'm currently diving deeper into Rust.
- 🧡 Huge fan of TanStack, React and the modern TypeScript ecosystem.
- 🐇 I use Bun for package management, scripts and application runtimes.
- 🗄️ I enjoy working with PostgreSQL, Redis, Drizzle ORM and BullMQ.
- 🐳 I self-host services using Docker, Proxmox and Forgejo.
- 🧪 I love turning random ideas into actual projects.
- 🔧 Clean code, strong typing and sensible automation make me happy.
