Tell me about the latest projects you have implemented, what you worked on, and whether they were built from scratch.

In my recent projects, I worked on developing a web service for automating customer data processing. The project was built from scratch: starting with architecture, choosing the technology stack, and ending with coding and setting up CI/CD.

The main tasks included:

• Developing a REST API in Python using FastAPI.
• Integrating with a PostgreSQL database.
• Implementing asynchronous task processing with Celery.

I also participated in a project to enhance an existing analytical tool, where I focused on code optimization and adding new features.

Thus, I have experience both in creating projects from scratch and in developing and maintaining existing systems.
