Cover Letter Generation Using Java, React and AI

I got idea about this Project from this famous micro saas idea book:
https://www.amazon.de/50-MICROSAAS-STARTUP-IDEAS-SOLUTIONS/dp/B0F1SR7C1D

Build an AI-powered Cover Letter Generator with a Java (Spring Boot) backend, a React frontend, and an LLM API (OpenAI/DeepSeek, etc.). In this step-by-step tutorial, we’ll go from architecture to a production-ready app that takes a job description + your resume highlights and crafts a tailored, ATS-friendly cover letter—fast.

What you’ll learn

Designing a clean API for text generation (Java/Spring Boot)

Securely calling an LLM (env keys, rate limits, retries)

Prompt design for high-quality, role-specific cover letters

React UI with form validation, live preview, and copy/download

Optional enhancements: tone selector, company research, and keyword boosting

Packaging & deployment tips (Docker + CI basics)

Tech stack

Backend: Java, Spring Boot, REST, DTOs, Validation

AI: LLM API (provider-agnostic), prompt templates

Frontend: React, Hooks, Fetch/Axios, Tailwind (optional)
