Who architected the project — you as a feature lead, together with the team, or the team lead?

The role in architectural design depends on the team structure and responsibility distribution.

• If you are a feature lead, you are usually responsible for the architecture within your feature or module, make implementation decisions, and interact with the team.
• The team lead is usually responsible for the overall project architecture, standards, integration between features, and technical guidance for the entire team.
• In some cases, the entire team jointly designs the architecture, especially if an agile approach and collective decision-making practices are used.

Thus, the project architecture can be:

• Team lead — if it concerns the global architecture.
• Feature lead — if architectural decisions relate to a specific area.
• Team — if decisions are made collectively.

It is important to clearly understand the responsibility zones and maintain communication between roles for successful architecture.
