What specific achievements have you implemented in your last project?

In my last project, I implemented data processing automation using Python. For example, I created a script for parsing and cleaning large CSV files, which reduced processing time from several hours to just a few minutes. I also integrated a logging and error handling module to improve the application's reliability.

Here's an example code for processing CSV files using pandas:

import pandas as pd

def process_csv(file_path):
    df = pd.read_csv(file_path)
    df_clean = df.dropna()  # remove empty values
    df_clean['new_column'] = df_clean['existing_column'] * 2
    df_clean.to_csv('processed.csv', index=False)

process_csv('data.csv')
