ResumeX

The problem

Most résumé builders render HTML and hope the print dialog behaves, most “ATS scores” are guesses, and students send one CV to twenty different jobs. ResumeX renders the actual PDF as you type, reads it back the way real parsers do, and gives every application its own tailored résumé.

What I built

• A live PDF engine: @react-pdf/renderer in a Web Worker, painted with pdf.js, so the preview is exactly what you download
• 52 templates in 7 categories, most generated by a spec-driven template engine (layouts, headers, palettes and fonts described as data)
• A deterministic ATS checker: 30+ explainable checks and weighted keyword matching against a job description, all in the browser
• A job-search workspace: a Career Profile, an application board that reads deadlines out of pasted job circulars, and per-job tailoring with no AI
• A Gemini assistant grounded in the app's own writing guide, for rewrites, cover letters and PDF/DOCX import; every AI change is shown for review
• Plans, credits and Paddle billing with an admin console, plus TOTP 2FA, rate limits on every route and 190+ server tests

Outcome

• Live at resumex.cc
• Opening as an invite-only beta for about 80 university students
• Started as my CSE299 project; grown into a full product
