Have you participated in a project from the very beginning — from architecture and pattern selection to feature implementation in production?

Yes, I have experience participating in a project from the very beginning. For example, I was involved in choosing the architecture of a SPA application, where we decided to use React with Redux for state management.

During the design phase, we discussed code organization patterns, component separation, routing approaches, and working with APIs. Then I implemented key features, integrated the UI with the backend, wrote tests, and participated in deployment.

Such experience allows for a deeper understanding of how architectural decisions impact the further development and maintenance of the product.
