How I Automate My Freelance Workflow with Python

As a freelance developer, managing multiple projects and clients can be overwhelming. To streamline my workflow and increase productivity, I've turned to Python for automation. In this article, I'll share my step-by-step approach to automating tasks, from project setup to invoicing, using Python scripts and tools.

Project Setup Automation

When a new project comes in, I need to set up a repository, create a new branch, and initialize a basic project structure. I've written a Python script using the gitpython library to automate this process.

import git
from git import Repo

def create_project(repo_name, branch_name):
    # Create a new repository
    repo = Repo.init(repo_name)

    # Create a new branch
    repo.git.checkout('-b', branch_name)

    # Initialize a basic project structure
    repo.git.mkdir('src')
    repo.git.mkdir('tests')

    # Commit the initial changes
    repo.git.add(all=True)
    repo.git.commit('-m', 'Initial commit')

# Example usage
create_project('my-new-project', 'main')

This script saves me around 10 minutes per project, and I can use that time to focus on more important tasks.

Time Tracking Automation

Accurate time tracking is crucial for freelancers to bill clients correctly. I use the pytz and datetime libraries to create a simple time tracking script.

import pytz
from datetime import datetime

def track_time(project_name, start_time, end_time):
    # Calculate the time difference
    time_diff = end_time - start_time

    # Convert the time difference to hours and minutes
    hours = time_diff.seconds // 3600
    minutes = (time_diff.seconds // 60) % 60

    # Print the time tracked
    print(f'Time tracked for {project_name}: {hours} hours {minutes} minutes')

# Example usage
start_time = datetime.now(pytz.utc)
# ... work on the project ...
end_time = datetime.now(pytz.utc)
track_time('my-project', start_time, end_time)

This script helps me keep track of the time spent on each project, making it easier to generate invoices.

Invoicing Automation

Creating invoices can be a tedious task, especially when dealing with multiple clients and projects. I use the fpdf library to generate invoices programmatically.

from fpdf import FPDF

def generate_invoice(client_name, project_name, hours_worked, rate):
    # Create a new PDF
    pdf = FPDF()

    # Add a page
    pdf.add_page()

    # Set the font and size
    pdf.set_font('Arial', size=15)

    # Add the client name and project name
    pdf.cell(200, 10, txt=f'Invoice for {client_name} - {project_name}', ln=True, align='C')

    # Add the hours worked and rate
    pdf.set_font('Arial', size=12)
    pdf.cell(200, 10, txt=f'Hours worked: {hours_worked}', ln=True, align='L')
    pdf.cell(200, 10, txt=f'Rate: ${rate}/hour', ln=True, align='L')

    # Calculate the total amount
    total_amount = hours_worked * rate

    # Add the total amount
    pdf.set_font('Arial', size=15)
    pdf.cell(200, 10, txt=f'Total amount: ${total_amount}', ln=True, align='R')

    # Save the PDF
    pdf.output('invoice.pdf')

# Example usage
generate_invoice('John Doe', 'my-project', 10, 50)
