Revisiting My GPT-Powered Resume Writer

I took another crack at my resume writer to write more accurately and also include a cover letter

This is a remake of my original resmue writer

A friend of mine is looking to get back out there and test the job market. It hasn't gotten any easier to find a new job since I made the first version, but I knew there were ways I could improve my script. The original was admittedly a good idea with poor execution. It did what it needed to, but it wasn't very robust. I created version 2 to address some of those concerns, make it more user-friendly, and make the outputs more accurate. Version 1 had an issue where it would confuse the users' existing job experiences with the job requirements. That appears to be fixed in this version. I also added a second Open AI call that generates a cover letter. In my current position, I have read a lot of cover letters, and ones written by AI are pretty easy to spot. I'd love to collaborate with a good prompt engineer to explore ways to make the cover letter match the user's writing style and voice.

Running it is similar to before, you just need to make sure that Pandoc is downloaded. If you don't have that, you can disable the line that executes the command to generate the pdf and just use the .md resume.

    prompt = f" Using markdown formatting, Help me craft a resume for the following job at {company}. The Job Description is: {description}. My name is {first_name} {last_name}, my phone number is {phone_number} and my email is {email}. Write the email and phone number in plaintext. My Address is {address}. The resume Section titles should be Bolded and Uppercased. The Company names should be bolded.
