Highlight past experiences implementing scalable solutions, explaining strategies used and outcomes achieved.

Example: “I focus on modularity and flexibility from the outset. By designing systems with interchangeable components, I allow for easier upgrades or replacements as technology and needs evolve. I also prioritize thorough documentation and clear coding practices to ensure that future engineers can understand and expand on what I’ve built.

In a past project, we developed a software tool for data analysis that needed to handle increasing data loads over time. We built it using a microservices architecture, which not only met the current demands but also allowed us to scale horizontally by adding more instances of specific services as needed. This approach has proven effective in adapting to growth without needing a complete overhaul, saving resources and maintaining continuity for the team.”
