LaTeX CV & Cover Letter Automation

Summary

A reproducible document generation pipeline built with PowerShell, Python, LaTeX, and GitHub Actions to automate multilingual CV and cover letter production. This system eliminates tedious manual formatting by generating, compiling, validating, and versioning tailored LaTeX documents from structured inputs.

It also supports batch compilation, selective document builds and digital signature embedding.

P.S. I use this system to manage my own resume and cover letters. The repository includes my CV, tracked and versioned to reflect updates over time.

Architecture

The project consists of:

• PowerShell build scripts for controlled LaTeX compilation
• Python + OpenAI API integration for automated cover letter generation
• CI/CD pipelines (GitHub Actions) for automated builds and artifact validation
• Template-based LaTeX structure with strict formatting validation
• Batch and targeted build support
• Digital signature embedding

Core Features

Automated CV Compilation

• Batch compilation of multiple .tex CV variants
• Selective target builds
• Debug mode for compilation tracing
• Output + auxiliary directory separation
• Non-blocking LaTeX error handling

AI-Generated Cover Letters

• Uses OpenAI API to generate tailored LaTeX cover letters
• Injects CV + job posting + system prompt
• Validates LaTeX output before writing
• Automatically backs up previous versions
• Enforces compile-safe LaTeX formatting

CI/CD Integration

• GitHub Actions pipeline for:
  • Automated builds
  • Artifact versioning
  • Reproducible PDF generation
• Ensures consistent output across environments

Digital Signature Injection

• Automatically embeds signature image into generated cover letters
• Centralized asset management

Requirements

• PowerShell 7+
• Python 3.10+
• OpenAI API Key
• TeX Live / MikTeX

Usage

Build All CVs

./build.ps1

Build Specific CVs

./build.ps1 -Targets english.tex,french.tex

Debug Mode (shows pdflatex output)

./build.ps1 -Debug

Build All Cover Letters

./buildCovers.ps1

Build Specific Covers

Signature Embedding

To embed a digital signature image at the bottom of each cover letter:

• Place your signature image in inputs/signature.png
• The script inserts \includegraphics into the final LaTeX before compilation
