Free resume optimization tool for any job, already 500 in first 24 hours

Hey all, I run a site called Dev List (job site for programmers), and after seeing a couple hundred resumes from our members that were ... not great, I built a tool that optimizes the resume for them

I was going to recommend other tools out there, but they were charging like $30/month, and as an engineer myself i wanted to see if I could just build my own

So within two weeks I built the feature, and announced it in my newsletter and offered it for free. And within 24 hours 500 resumes were created :)

Within 30 seconds you go from a job listing to a downloadable PDF of your resume optimized for that job

Here's how we optimize:

1. ATS friendly formatting (you'd be surprised how many resumes I've seen that do not have this)

2. ATS optimized keywords in your resume (how ATS filters out resumes before getting to the recruiter)

3. Highlighting experiences and skills you have according to the job

How I built it:

1. OpenAI for ai optimization stuff and resume parsing

2. Lots of prompt tweaking / iterations (I tried doing fine-tuning of the model but prompt adjustments gave better results)

3. Puppeteer for generating the pdf

4. Nextjs web app

I'm pretty excited about this feature for our users. So many had bad resumes that are now able to get great ones and for free :)

(btw you can just paste in a job description as well, so even if you're not an engineer you can try it out too for free: DevList )
