Project Overview

The aim of this project is to build a WEB application in Streamlit that will scan and improve a resume using instruction-tuned Large Language Models (LLMs).

We leveraged the power of LLMs, specifically Chat GPT from OpenAI and Gemini-pro from Google, to extract, assess, and enhance resumes.

We used Langchain, prompt engineering and retrieval augmented generation techniques to complete these steps.

Installation

This project requires Python 3 and the following Python libraries installed:

streamlit, langchain ,langchain-openai, langchain-google-genai, faiss-cpu, tiktoken, python-dotenv, pdfminer, markdown

The full list of requirements can be found in requirements.txt

File Descriptions

  • Streamlit_App folder: contains the Streamlit application.

    • requirements.txt: contains the required packages for installation.
    • keys.env: Your OpenAI, Gemini, and Cohere API keys are stored here.
    • llm_functions.py: reads LLM API keys from keys.env and instantiates the LLM in Langchain.
    • retrieval.py: the script used to create a Langchain retrieval, including document loaders, embeddings, vector stores, and retrievers.
    • app_constants.py: contains templates for creating LLM prompts.
    • app_sidebar.py: the sidebar is where you can choose the LLM model and its parameters, such as temperature and top_p values, and enter your API keys.
    • resume_analyzer.py: this file contains the functions used to extract, assess, and improve each section of the resume using LLM. It is the core of the application.
    • pp_display_results.py: the script used to display resume sections, assessments, scores, and improved texts.
    • app.py: It's the main script of the app. It calls all the scripts and is used to run the Streamlit application.
  • Notebooks folder: contains the project's notebook.

Instructions

To run the app locally:

  1. Create a virtual environment: python -m venv virtualenv

  2. Activate the virtual environment :

    Windows: .\virtualenv\Scripts\activate

    Linux: source virtualenv/bin/activate

  3. Install the required dependencies pip install -r requirements.txt

  4. Add your OpenIA, Gemini, and Cohere API keys to the keys.env file. You can get your API keys from their respective websites.

  1. Start the app: streamlit run ./Streamlit_App/app.py
  2. Select the LLM provider (either OpenAI or Google Generative AI) from the sidebar. Then, choose a model (GPT-3.5, GPT-4 or Gemini-pro) and adjust its parameters.
  3. Use the file uploader widget to upload your resume in PDF format.
  4. πŸš€ To analyze and improve your resume, simply click the 'Analyze resume' button located in the main panel.

Screenshots

Here is a screenshot of the application.


The results of the resume analysis and improvement are shown below.

First, the resume's overview, top 3 strengths, and top 3 weaknesses are displayed.


The scores are then displayed to give a general indication of the resume's quality. The resume is evaluated based on eight sections, each scored out of 100: contact information, summary, work experience, skills, education, language, projects, and certifications.

Finally, the analysis of each section is presented in a st.expander. For instance, here is how the work experience is displayed.
