Describe the latest project you worked on and your contribution to it.

In my last project, I worked on a web application for analyzing user data. My main task was to develop backend logic in Python using the Flask framework.

I implemented an API for data collection and processing, and also integrated the system with a PostgreSQL database. Additionally, I optimized data processing algorithms, which reduced the service response time by 30%.

Example of a Flask endpoint code:

from flask import Flask, request, jsonify
app = Flask(__name__)

@app.route('/data', methods=['POST'])
def receive_data():
    data = request.json
    # data processing
    return jsonify({'status': 'success'})

if __name__ == '__main__':
    app.run()

I also participated in writing tests and documentation for the API.
