## 1. Product Summary & Value Proposition

- **Name**: IhateLaTeX (by Resume Smashers)
- **Primary Function**: Free, offline, private LaTeX resume builder and CV generator.
- **Problem Solved**: Traditional LaTeX (Overleaf, TeXLive desktop) has a steep learning curve, requires syntax knowledge, and is slow to set up. Traditional builders (Canva, Zety, Novoresume) produce non-standard PDFs with tables and floating boxes that fail ATS scanners (Workday, Lever, Greenhouse) and charge recurring subscriptions.
- **Solution**: IhateLaTeX gives users the unbeatable typographic precision and 100% ATS compliance of LaTeX with the ease of an intuitive form editor, compiling directly to PDF in the browser via WebAssembly without charging fees or tracking user data.

## 2. Technical Architecture

- **Compiler**: In-browser SwiftLaTeX / PdfTeX compiled to WebAssembly (WASM).
- **Asset Pipeline**: Preloaded TeXLive font packages and LaTeX class definitions cached via ServiceWorker and IndexedDB.
- **Privacy Model**: 100% Client-Side execution. No resume text, contact details, or job history is ever transmitted over network sockets or saved on backend databases.
- **PWA Ready**: Works completely offline after initial load. Can be installed as a desktop or mobile application.

## 5. ATS Scoring Criteria & Action Verb Formula Guide

Applicant Tracking Systems (ATS) like Workday, Greenhouse, Lever, and Taleo parse PDFs by extracting the raw text stream. IhateLaTeX ensures every PDF generated contains clean UTF-8 text streams with zero graphical distortion.

### Recommended Bullet Point Frameworks:
1. **Google XYZ Formula**:
   *"Accomplished [X] as measured by [Y], by doing [Z]"*
   - Example: *"Reduced backend API p99 latency by 35% (Y) by refactoring PostgreSQL queries and implementing Redis caching (Z), saving $12,000 monthly in compute costs (X)."*
2. **STAR Method**:
   - Situation: Context of the challenge.
   - Task: Specific responsibility.
   - Action: Concrete technical steps taken.
   - Result: Quantifiable outcome (%, $, hours saved).
