[100-Day AI bootcamp] Day 9: AI Resume Builder

Creating a resume that stands out and is tailored to specific job roles can be challenging. Leveraging artificial intelligence (AI) to automate and optimize this process not only simplifies resume creation but also enhances its effectiveness. This guide provides a comprehensive walkthrough of building an AI-powered resume builder using FastAPI for the backend and React for the frontend. The integration of AI technologies, deployment strategies, and opportunities for affiliate marketing are also explored.

Integrating AI into Resume Building

Automating resume optimization through AI involves using natural language processing to analyze and enhance resume content. By utilizing AI models like OpenAI's GPT-3, the application can suggest improvements, tailor content to job descriptions, and ensure compatibility with Applicant Tracking Systems (ATS).

Building the Backend with FastAPI

FastAPI is a modern, asynchronous web framework for building APIs with Python. It offers high performance and ease of use, making it ideal for developing efficient backend services.

Setting Up the Development Environment

1. Create a Virtual Environment

   python -m venv venv
   source venv/bin/activate  # For Windows: venv\Scripts\activate

2. Install Required Packages

   pip install fastapi uvicorn sqlalchemy passlib[bcrypt] python-multipart python-dotenv openai

Database Configuration with SQLAlchemy

Using SQLAlchemy ORM simplifies database interactions. Define models for users and resumes.

from sqlalchemy import Column, Integer, String, Text, ForeignKey
from sqlalchemy.orm import relationship
from database import Base

class User(Base):
    __tablename__ = 'users'
    id = Column(Integer, primary_key=True, index=True)
    email = Column(String, unique=True, index=True)
    hashed_password = Column(String)
    resumes = relationship("Resume", back_populates="owner")

class Resume(Base):
    __tablename__ = 'resumes'
    id = Column(Integer, primary_key=True, index=True)
    title = Column(String, index=True)
    content = Column(Text)
    optimized_content = Column(Text)
    owner_id = Column(Integer, ForeignKey('users.id'))
    owner = relationship("User", back_populates="resumes")

Authentication and Security

Implement JWT (JSON Web Tokens) for secure user authentication.

# auth.py
from datetime import datetime, timedelta
from jose import JWTError, jwt
from passlib.context import CryptContext

SECRET_KEY = "your_secret_key"
ALGORITHM = "HS256"
ACCESS_TOKEN_EXPIRE_MINUTES = 30
pwd_context = CryptContext(schemes=["bcrypt"], deprecated="auto")

def create_access_token(data: dict):
    data_copy = data.copy()
    expire = datetime.utcnow() + timedelta(minutes=ACCESS_TOKEN_EXPIRE_MINUTES)
    data_copy.update({"exp": expire})
    encoded_jwt = jwt.encode(data_copy, SECRET_KEY, algorithm=ALGORITHM)
    return encoded_jwt

API Endpoints

Define routes for user registration, login, and resume management.

# main.py
from fastapi import FastAPI
from routes import auth_routes, resume_routes

app = FastAPI()

app.include_router(auth_routes.router)
app.include_router(resume_routes.router)

Integrating AI Services with OpenAI

Utilize OpenAI's GPT-3 for resume optimization.

# ai_service.py
import openai

openai.api_key = 'YOUR_OPENAI_API_KEY'

def optimize_resume(resume_content: str, job_description: str) -> str:
    prompt = f"Optimize the following resume for the job description: {job_description}\nResume:\n{resume_content}"
    response = openai.ChatCompletion.create(
        model="text-davinci-003",
        messages=[{"role": "user", "content": prompt}],
        max_tokens=500
    )
    optimized_resume = response['choices'][0]['message']['content'].strip()
    return optimized_resume

Developing the Frontend with React

React provides a robust platform for building interactive user interfaces.

Setting Up the React App

npx create-react-app resume-builder-frontend
cd resume-builder-frontend
npm install axios

Creating Components

Develop components for authentication, resume creation, and optimization.

// OptimizeResume.js
import React, { useState } from 'react';
import axios from 'axios';

function OptimizeResume() {
  const [jobDescription, setJobDescription] = useState('');
  const [optimizedContent, setOptimizedContent] = useState('');

  const handleOptimize = async () => {
    const response = await axios.post('/resume/optimize', { jobDescription });
    setOptimizedContent(response.data.optimized_resume);
  };

  return (
    <div>
      <textarea onChange={(e) => setJobDescription(e.target.value)} placeholder="Enter Job Description" />
      <button onClick={handleOptimize}>Optimize Resume</button>
      <pre>{optimizedContent}</pre>
    </div>
  );
}

export default OptimizeResume;

Handling Authentication

Manage user sessions and tokens.

// AuthService.js
import axios from 'axios';

const AuthService = {
  login: (email, password) => axios.post('/auth/login', { email, password }),
  register: (email, password) => axios.post('/auth/register', { email, password }),
};

export default AuthService;

Connecting Frontend and Backend

Ensure proper configuration of CORS and API endpoints.

# main.py
from fastapi.middleware.cors import CORSMiddleware

app.add_middleware(
    CORSMiddleware,
    allow_origins=['http://localhost:3000'],
    allow_credentials=True,
    allow_methods=["*"],
    allow_headers=["*"],
)
