🙋 About Me

I'm a full-stack developer based in Drammen, Norway, with a strong focus on back-end architecture, cloud deployments, and clean API design. I enjoy turning complex problems into maintainable, well-structured solutions.

  • 🔭 Currently building BIT4 — a handcrafted 4-bit CPU emulator with custom ISA, ALU, RAM and VPU, built from scratch in C#, as part of a broader hobby in building hardware emulators
  • 🔌 Built microservices using four different communication patterns — REST gateway, WebSockets, RabbitMQ, and ETL data streaming
  • 📈 Actively building toward Kotlin + Spring Boot — practicing the domain and REST layers separately in Java (SPRINGBOOT1, SPRINGBOOT5) ahead of combining them into KotlinBankingAPI; also expanding into GCP and Terraform/IaC on top of existing Azure and Docker/Kubernetes experience
  • 🧑‍🏫 Former instructor at JobLoop and mentor at Noroff — taught C#, ASP.NET, Node.js and JavaScript
  • 🤖 Daily user of GitHub Copilot and Cursor for AI-assisted development
  • 🌍 Fluent in 6 languages: English, Norwegian, Turkish, German, French, Russian
