Can you give an example of a task with high uncertainty that you had to perform?

In one of my Go projects, I had to implement a real-time data processing system where the requirements and input data formats constantly changed, and there was no documentation. The task involved a high level of uncertainty because:

• There were no clear specifications regarding data format and volume.
• Scalability and fault tolerance needed to be ensured.
• Integration with external services was required, whose APIs changed without notice.

To solve this, I used an iterative approach: first, I created a minimally viable prototype that could accept and parse data in a basic format. Then, I added processing for new formats and scenarios as requirements emerged. I actively used Go interfaces and abstractions for code flexibility. I also implemented logging and monitoring to quickly identify and fix errors in data handling.
