Answer: Can you explain a difficult technical problem you were faced with in your previous role and how you resolved it?

During my previous role as a software developer, I encountered a complex technical issue with a legacy system that was causing frequent downtime and performance issues. The problem stemmed from outdated code that was difficult to maintain and lacked proper documentation.

To address this challenge, I first conducted a thorough analysis of the codebase and identified the key areas that were causing the issues. I then proposed a plan to refactor the code using more modern and efficient technologies, such as microservices architecture and automated testing.

Working closely with the team, we incrementally implemented the changes, testing each step thoroughly to ensure backward compatibility and prevent any unexpected issues. Through meticulous debugging and optimization, we were able to improve the system's stability and performance significantly.

By leveraging my problem-solving skills, technical expertise, and effective collaboration with team members, we successfully resolved the difficult technical problem and transformed the legacy system into a more reliable and scalable solution.
