Every time I applied to a job, I'd stare at a JD and a resume side by side, trying to guess which keywords mattered and which gaps would actually come up in the interview. I built **CareerReady** to do that comparison for me, and then let me practice the exact gaps it found.

Biết mình thiếu gì. Luyện đúng chỗ. Tự tin phỏng vấn.Know your gaps. Practice right. Interview with confidence.

CareerReady helps developers prepare for job interviews. Paste a job description and upload your CV — the AI analyzes your skills against the JD, surfaces matched/missing skills with CV quick tips, and generates a mock interview covering the gaps.

| Module | Description |
|---|---|
Skill Analyzer |
Paste or upload a JD (PDF/DOCX) + upload CV (PDF) or enter skills manually. AI outputs matched skills, missing skills (with priority), and CV quick tips. |
Mock Interview |
Two modes — Project Deep Dive and Technical Quiz — generated from your CV/JD analysis. Answer via text or voice; AI scores the session and gives feedback with a full transcript. |
Dashboard |
Recent analyses, mock interview history, and score tracking across sessions. |

Note: there is currently no learning-roadmap generation feature — the Skill Analyzer surfaces gaps…

The interesting part wasn't the AI call, it was making the *waiting* feel honest. The analyze pipeline is a few real steps — parsing the CV/JD, validating the JD is actually a job description (so someone can't paste garbage and burn a Gemini call), uploading files, then the actual skill-gap analysis — and I stream each step's status to the frontend over SSE instead of showing a generic spinner. If step 1 fails, the user sees *that* step fail, not a blank error.

so auth cookies stay same-origin across the two hostsIt's free to use at [career-ready.site](https://career-ready.site). I'd genuinely appreciate feedback, especially on whether the missing-skills output feels accurate, and whether the mock interview questions feel like something you'd actually get asked.

If you want to poke at the code, it's open on [GitHub](https://github.com/GiottoPham/dev-career-ready).
