Tell me about a complex solution that you had to design from scratch and develop.

In one of my projects, I had to design and implement a system for dynamic loading and display of complex forms with many interdependent fields from scratch. The task was to enable forms to change without the need for frontend recompilation — form configurations were stored on the server and transmitted to the client.

To achieve this, I developed an architecture where each form was described by a JSON schema with validation rules and conditions for displaying fields. On the client side, a universal form renderer was implemented, which dynamically built the interface based on the schema, handling input and validation.

A key feature of the solution was support for complex dependencies between fields, such as displaying certain fields depending on the values of others, as well as asynchronous data loading for auto-completion. This approach significantly accelerated the development of new forms and simplified maintenance.
