Tell about your experience in developing architectural solutions in projects.

In my experience of developing architectural solutions, I usually start with analyzing the project requirements and constraints, then choose an appropriate architectural style (for example, microservices, monolith, event-driven).

Main steps:

• Defining key components and their interactions.
• Selecting technologies and tools suitable for performance, scalability, and support requirements.
• Designing APIs and contracts between modules.
• Ensuring testability and extensibility.

For example, in one project, I designed a system based on microservices using REST API and message queues for asynchronous processing, which allowed easy scaling of load and quick deployment of new features.

A code example of a simple microservice in Python with Flask:

from flask import Flask, jsonify

app = Flask(__name__)

@app.route('/status')
def status():
    return jsonify({'status': 'ok'})

if __name__ == '__main__':
    app.run(port=5000)

This approach ensures modularity and ease of maintenance.
