Behind the scenes: How we trained VitoCV's AI to beat ATS filters 🤖

Since a few of you asked about the AI generation quality in the comments, I wanted to share a quick behind-the-scenes look at how the models behind VitoCV actually work.

When I started building this, I realized standard LLMs are often too generic or 'fluffy' for resumes. To fix this, I focused heavily on prompt engineering and fine-tuning the AI specifically against real-world ATS constraints and FAANG resume guidelines.

Specifically, the AI is trained to:

  1. Prioritize Action Verbs: It automatically restructures sentences to start with strong, impactful action verbs.

  2. Quantify Results: It actively looks for metrics in your input (or prompts you for them) to format points in the classic 'Accomplished [X] as measured by [Y], by doing [Z]' format.

  3. ATS Keyword Mapping: It cross-references your bullet points with standard industry keywords so the ATS parsers don't filter you out.
