Sample Response: Associate

As a Web Developer at SecureNet Solutions, I was involved in an initiative to protect our company's APIs from bot scraping. Our APIs were being frequently hit by bots which led to unwanted excess traffic affecting our services. We decided to tackle this issue head-on by implementing more sophisticated API security measures.

We started using IP rate-limiting techniques combined with machine learning algorithms to detect unusual traffic patterns. Whenever a suspicious activity was detected, the source IP was temporarily blocked. In addition, we incorporated a layer of defense using reCAPTCHA v3, which was effective in detecting bots by providing risk analysis scores for each request.

After implementing these strategies, we noticed a significant decrease in bot traffic. We managed not only to protect our APIs but also to maintain high-quality service to our genuine users, enhancing their experience and ensuring reliable, secure access to our services.
