Building scalable, data-driven applications — from React frontends to .NET and Node.js backends
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
