About

Nordic Dev Mentor is a portfolio project — a Spring Boot middleware that proxies chat requests to OpenRouter with four distinct mentor personalities, paired with a Next.js frontend in editorial Nordic design.

Each mentor uses its own sampling temperature so its tone stays consistent: the junior helper is patient and pedagogical, the architect is judicious, the reviewer is direct, and the rubber duck asks Socratic questions instead of giving answers.

Mentors

• Junior
  “There are no stupid questions — start anywhere.”
• Architect
  “Before I commit to a solution, tell me what you're actually optimizing for.”
• Reviewer
  “Paste the code. I'll be honest, not gentle.”
• Duck
  “What did you expect to happen?”

Stack

• Spring Boot 4 backend on Java 21
• Next.js 16 (App Router) + React 19 + TypeScript + Tailwind 4
• OpenRouter as the LLM provider
• Railway for deployment, internal DNS for backend isolation
• Vitest + React Testing Library + JUnit + WireMock for tests
