Tech Stack

Layer	Technology
Backend	Java 17, Spring Boot 3.2
Frontend	Thymeleaf, HTML5, CSS3, Vanilla JS
AI Engine	Claude Sonnet 4 API (Anthropic)
PDF Engine	YtoTech LaTeX API
Database	H2 (in-memory)
Build	Maven

Quick Start

Prerequisites

• Java 17+
• Maven 3.6+
• A Claude API key from Anthropic

Running Locally

cd cv-generator

# Set your API key
# Windows CMD:  set CLAUDE_API_KEY=sk-ant-api03-your-key
# PowerShell:   $env:CLAUDE_API_KEY="sk-ant-api03-your-key"
# Linux/Mac:    export CLAUDE_API_KEY=sk-ant-api03-your-key

mvn spring-boot:run

Open http://localhost:8055.

Writable Data Directory

On first run the app copies two default files from resources into ./data/:

File	Purpose
data/candidate-data.json	Your personal profile (name, experience, skills, etc.)
data/cv-gen-system-prompt.txt	The system prompt sent to Claude

Edit these files via the Profile Editor page (/profile) or directly on disk. The app always reads from ./data/ (falling back to bundled defaults if a file is missing). Set APP_DATA_DIR to change the location.

Configuration

Key properties in application.properties:

server.port=${PORT:8055}

claude.api.key=${CLAUDE_API_KEY:}
claude.api.model=claude-sonnet-4-20250514
claude.api.max-tokens=8000
claude.api.timeout=120000

latex.api.url=https://latex.ytotech.com/builds/sync

app.data.dir=${APP_DATA_DIR:./data}

How It Works

1. User pastes a Job Description in the web form
2. App calls the Claude API with the system prompt + candidate profile + JD
3. Claude generates a tailored LaTeX CV, keyword analysis, match scores, and a coach brief
4. App compiles the LaTeX to PDF via the YtoTech API
5. User downloads the PDF and/or LaTeX source
