Building a Serverless ChatGPT Powered Resume Assistant - Basics

project origin

A few weekends ago, I was tempted to build something with the OpenAI API. As a career changer entering the cloud space and someone who has worked in the early career talent space, I am acutely aware of how important and difficult it is for candidates to write a relevant resume for the role they are applying for. So, I decided to make a resume assistant powered by ChatGPT.

There are already a lot of articles written about Large Language Models (LLMs) and ChatGPT in particular, I don't really want to add to them. One thing I would like to address is that criticism of the LLM is just assertive and convincing bullshit. It's not a great trait for writing academic papers, but are there applications where it could be an advantage?

If you think about it, a resume can also be considered confident, convincing bullshit. No, I'm not saying it's acceptable to lie on a resume, but we often find ourselves writing a resume to expand our experience a bit so we can better fit a given job description . Speaking of which..

Job descriptions are a similar kind of aspirational crap. Requirements are based on an old job that no longer really matches the job, or just a description of the previous person's experience (the person who left made 20% more than they gave you). So the CV, job description, and LLM together form what I call the "honest trinity"

So, having determined that LMM is the perfect resume assistant, we will now build a serverless application that, given a "resume" and a job description, can customize a resume for the job through a virtual resume review, namely and your talk.

plan

Since most of this article was written in one article, and it was too long , I decided to split it into 4 articles.

Introduction and some background (this post)
Build a Python function that can be run and tested locally from the command line
Deploy the function to the cloud using the AWS CDK (Python) (but still interact with it through the CLI)
Deploy the frontend so we can allow others to use the service

This should keep things a bit smaller, and allow anyone who wants to build it (or make their own modifications to it) to focus on one file or area generally, instead of jumping around like a maniac.

How conversations with ChatGPT work

Let's talk about the OpenAI library and how ChatGPT conversations work.

First , every conversation has three participants, assistant- the chatbot, user- the person chatting with the chatbot, and system- a hidden but important participant who sets the tone of the conversation.

Second , this system message is your "secret weapon". Something that differentiates your bot from just chatting with ChatGPT. System messages allow you to set rules and constraints that will apply for the duration of a conversation. Here, we can indicate to chatbots that it is a useful assistant in resume review and "uses transferable skills if they lack direct experience". This is probably something you want to keep private, or someone else could copy your million dollar idea!

Third , the OpenAI API doesn't "remember" anything. Every time you pass a request to it, you need to provide all the context needed to generate the relevant completion. This means that the first request might look like this:

<span style="color:var(--syntax-text-color)"><span style="color:var(--syntax-text-color)"><code><span style="color:var(--syntax-text-color)">[</span>
  <span style="color:var(--syntax-text-color)">{</span><span style="color:var(--syntax-string-color)">'role'</span><span style="color:var(--syntax-text-color)">:</span><span style="color:var(--syntax-string-color)">'system'</span><span style="color:var(--syntax-text-color)">,</span><span style="color:var(--syntax-string-color)">'content'</span><span style="color:var(--syntax-text-color)">:</span><span style="color:var(--syntax-string-color)">'You are a resume bot named Resume Bot 3000'</span><span style="color:var(--syntax-text-color)">},</span>

<span style="color:var(--syntax-text-color)">]</span>
</code></span></span>

Your second request might look like this (we'll talk about parsing responses in a minute):

<span style="color:var(--syntax-text-color)"><span style="color:var(--syntax-text-color)"><code><span style="color:var(--syntax-text-color)">[</span>

Have you ever had a job or other experience where you had to handle cash or facilitate transactions?'</span><span style="color:var(--syntax-text-color)">},</span>
  <span style="color:var(--syntax-text-color)">{</span><span style="color:var(--syntax-string-color)">'role'</span><span style="color:var(--syntax-text-color)">:</span><span style="color:var(--syntax-string-color)">'user'</span><span style="color:var(--syntax-text-color)">,</span><span style="color:var(--syntax-string-color)">'content'</span><span style="color:var(--syntax-text-color)">:</span><span style="color:var(--syntax-string-color)">'Well, maybe not a job but I volunteered at school basketball games selling tickets for admission and also working at the concession stand.

<span style="color:var(--syntax-text-color)">]</span>
</code></span></span>

In order for ChatGPT to understand what's going on, it basically needs the entire conversation every time. Everything is new to it. This means that the longer the conversation lasts, the more context is built and the more expensive your requests become.

The context price of gpt-3.5-turbo is $0.0015/1k tokens (according to the openAI pricing page, about 750 words), and the response price is $0.003/1k tokens. This can be fairly cheap, but it can also easily get out of hand if there are a lot of people having long conversations. Be sure to set your account limits in the billing section.

While the ultimate goal of this project is to deploy it on AWS and open it up to the world, we will first create a python function that can be run locally. We can modify it later to run in AWS Lambda. So even though this code ends up needing to be placed in a directory of the CDK project, we'll skip that part and refactor it later if needed. We hope to get some glorious feedback on working code soon!

Setup files and virtual environments

So let's create a directory called chat_app, which we will first use to run our chatbot locally and then communicate with our deployed AWS Lambda function. Once we've created the directory, we can add the files we need to a small python project:

<span style="color:var(--syntax-text-color)"><span style="color:var(--syntax-text-color)"><code><span style="color:var(--syntax-text-color)">mkdir </span>chat_app
<span style="color:var(--syntax-text-color)">cd </span>chat_app
<span style="color:var(--syntax-text-color)">touch </span>app.py requirements.txt
</code></span></span>

Now add the OpenAI library to yours requirements.txt. I'll be pinning the latest version available at the time of writing, but you can check out the latest version while reading this.

<span style="color:var(--syntax-text-color)"><span style="color:var(--syntax-text-color)"><code># chat_app/requirements.txt

openai==0.27.8
</code></span></span>

Note that I'm trying to be as clear as possible which file I'm working on by adding a comment to all my code blocks telling you where I am. When I use an external library or module, I also do my best to show its imports at the top of the file. You can skip this part of the code if it was already imported in the previous step.

requirements.txtWe have now declared our first external dependency in our create virtual environment and installed that dependency in the virtual environment. If you plan to commit any of these to a git repository, be sure to add this .venv/to your .gitignore.

<span style="color:var(--syntax-text-color)"><span style="color:var(--syntax-text-color)"><code>python3 <span style="color:var(--syntax-error-color)">-m</span> venv .venv
<span style="color:var(--syntax-text-color)">source</span> .venv/bin/activate   
pip <span style="color:var(--syntax-text-color)">install</span> <span style="color:var(--syntax-error-color)">-r</span> requirements.txt
</code></span></span>

Now let's move into our python file. We'll import our module, setting the OpenAPI key we got from our OpenAI account. (Are you doing it right? If you aren't, please do it!)

Add your key to a local environment variable like this, but use your own:

<span style="color:var(--syntax-text-color)"><span style="color:var(--syntax-text-color)"><code><span style="color:var(--syntax-text-color)">export </span><span style="color:var(--syntax-text-color)">OPENAI_API_KEY</span><span style="color:var(--syntax-error-color)">=</span><span style="color:var(--syntax-string-color)">"sk-Th1si5n0tmyactua1k3y"</span>
</code></span></span>

Let's test your key with a simple request and see what happens:

<span style="color:var(--syntax-text-color)"><span style="color:var(--syntax-text-color)"><code><span style="color:var(--syntax-comment-color)"># chat_app/app.py

</code></span></span>

So we're creating a messaging dialog that is triggered by that system message and sending the user a question about the assistant's name.

The test response is accessible .choices[0].message.content, so we print it out.

This is the response I get when I run:

<span style="color:var(--syntax-text-color)"><span style="color:var(--syntax-text-color)"><code> ⚡  python app.py                                                             
I am a language model AI and my name is OpenAI. But for the purpose of this conversation, you can refer to me as Mr. Boots, the cat. Meow!
</code></span></span>

You may end up with something slightly different. Language models are just that. But guess what! We're done chatting! Now let's turn this into an infinite loop (with some escaping) so we can have a real conversation with Mr. Boots.

We'll take some input from the user, assume it's not one of our escape commands, and enter our loop. We add that input to the message list and request completion. We'll then print that response and append it to the message list, and wait for another user to respond. User input will determine whether to enter the loop again, or to exit the loop.

Our first conversation!

Goodbye Mr. Boots! We have a resume to work on!

So let's think about what our resume assistant needs to do.

ready system message
Get a resume or description of a job seeker (candidate)
get some kind of job description
Talk to candidates to get more information about their experiences
Prepare a Better Resume

Once we store it in the cloud, we'll need to add some other stuff, but we'll deal with that in the next article.

A simple start:

<span style="color:var(--syntax-text-color)"><span style="color:var(--syntax-text-color)"><code> ⚡  python app.py              
Please provide your resume or tell me about yourself
My name is Jimmy Jimbert and I worked at McDonalds as a team member from Jan 10 2022 to now. I did all of the jobs there. 
What job do you want?
I would like to be a bank teller. 
Mr. Boots: Great, Jimmy! It sounds like you have experience working in a customer service-oriented role, which is helpful when working as a bank teller. Can you please provide more information about your responsibilities at McDonald's, especially those that could be transferable to a bank teller role, such as handling financial transactions, upholding high levels of accuracy and attention to detail, and working as a team with colleagues and customers? Additionally, do you have any experience handling cash efficiently and accurately? Finally, do you have any additional education or certification related to banking or finance that may be relevant for a bank teller role?
exit
Mr. Boots: GoodBye
</code></span></span>

At first, this seemed like a good start to me. AI assistants have already mastered some activities related to both positions, such as cash handling and accuracy. That's the core thing we want it to do.

We also need to make some changes, such as we keep the format of the assistant response as coming from "Mr. Boots" hahaha.

Second, it became clear that we needed a better way to provide assistants with our resumes. Pasting blocks of multi-line text is more work than it's worth, so it's best to just let it load a resume.txtjob description called jd.txt. Nor will this work go to waste as we move on to further steps.

Let's make these files for testing. I'll keep trying to get Jimmy a job at the bank, but if you're doing it yourself, you might as well use your info and the job you're looking for!
