about_me

The short version — longer story on its own page

I'm Danial Choopan, a Software Engineer who builds scalable, high-performance systems with ASP.NET Core, Spring Boot and Laravel. I architect with Clean Architecture and SOLID, design RESTful APIs, and manage databases like SQL Server and PostgreSQL.

I also ship real Android apps (Kotlin/Jetpack Compose), run DevOps pipelines (Docker, K8s, GitHub Actions), dabble in AI/LLM (RAG, local inference) — and once built a Linux distro from scratch.
