Full Stack Engineer · Backend Systems · Self-Hosted Applications & Cloud-Native

Portfolio

I build reliable backend services, modern web applications, and self-hosted tools — with an emphasis on clean architecture, performance, and practical engineering.

👨‍💻 About Me

  • 🏠 I enjoy building self-hosted applications that give users greater ownership and control over their data.
  • ⚙️ I build backend systems, APIs, distributed services, and full-stack applications.
  • 🌐 I work across the stack with Spring Boot, SvelteKit, Next.js, React, and TypeScript.
  • 🐧 I’m interested in Linux, containers, Kubernetes, cloud infrastructure, and observability.
  • 🔐 I care about security, reliability, clean architecture, and data ownership.
  • 🧪 I prefer building practical software that solves real problems over isolated demos.
