Nikan Eidi
Full-stack developer based in Canada, and a Computer Programming & Analysis graduate from Seneca Polytechnic. I build real systems — backend APIs, databases, auth, the parts that actually run in production — and write about what I'm actually learning as I build them, not just when a project ships.
