Every job deserves a resume written for it. Nobody has time to write twelve. So I built a Claude Code skill that does it. I keep one master resume with everything I've ever done, hand it a job posting, and it researches the company, picks what matters for that role and lays it out as a clean one-page PDF.
Same person, two different jobs
Here's one master resume, tailored twice. For a Google Cloud AI/ML role it leads with my distributed-inference debugging and ML infrastructure work. For York Space Systems' battle-management role it rewrites the summary around aerospace and pulls in my defense orbital-data-fusion project. Same facts, a different story for each reader.
Real outputs from August 2026. Contact details are blurred.
Set up once
Setup is two jobs. Install the PDF renderer once. Then build the master resume: feed it every old resume I have and my transcript, and it merges them into one file that keeps everything, with no length limit. When I start a new job or ship a project, one command adds it.
From then on it's a MARVIN skill, so I just say "tailor my resume" and paste a link.
One run, start to finish
It fetches the posting, even from job sites that build the page with JavaScript, and researches the company, the role and who's hiring. Then it matches my experience to the job by meaning, not keywords, and scores every entry on relevance and recency. Strong material makes the cut and weak material doesn't; there are no quotas.
A render step fits the result to exactly one page, stepping the type between 13pt and 8.5pt. Cover letters start from what I actually say happened, never from rephrased resume bullets. The finished PDFs land in my Applications folder and open on screen.
The master resume and every tailored copy stay on my machine. The public repository is code only.
How MARVIN keeps it running
Resume Tailor doesn't live alone. MARVIN routes my request to it and brings along what it learned last time, like which job sites need a fallback to read.
Every time its code changes, hooks refresh MARVIN's skill index, save the lesson to a shared knowledge base, scan the code for problems and propose improvements to the skill itself. Code syncs to GitHub; my resume data syncs only to my own server. The Metrics tab counts every call, so I can see it's actually being used.
Built with MARVIN
Resume Tailor is one of the skills in MARVIN, the AI development system I built around Claude Code.
