With over 8 years of experience building large-scale backend systems, I have deep expertise in Java and Python, and have successfully integrated LLM solutions into production environments to improve user experience. My hands-on experience with data streaming frameworks like Flink and Spark, combined with a strong grasp of system design, aligns well with the challenges of this role. I am particularly drawn to Binance's mission of accelerating cryptocurrency adoption and would thrive in a fast-paced, remote-first culture. Thank you for considering my application. I look forward to contributing to your global team. Copy Sample interview questionsHow would you design a highly scalable backend for an AI chatbot handling millions of customer service requests?I would use a microservices architecture with asynchronous message queues for request processing, implement caching for frequent queries, and integrate LLM APIs with rate limiting and fallback mechanisms. A distributed data pipeline using Flink would handle streaming data for real-time analytics and model improvements. Can you describe your experience integrating LLMs into production applications? What challenges did you encounter? In a previous project, I integrated a fine-tuned LLM for customer support. Challenges included latency management, cost optimization, and ensuring reliable fallback responses. I addressed these by batching requests, implementing prompt caching, and designing a hybrid system with rule-based fallbacks for critical queries. How would you use Flink/Spark to process chatbot logs and improve the AI model over time? I would set up a streaming pipeline with Flink to ingest chat logs in real-time, extract intents and sentiment, and generate features for training data. Spark could be used for batch processing to retrain models and produce performance metrics. This enables continuous improvement of the chatbot's accuracy. What strategies do you use to ensure low latency and high availability for large-scale systems? I focus on designing stateless services, using load balancing, implementing circuit breakers, and leveraging distributed caching. Additionally, I would use auto-scaling based on traffic patterns and perform regular load testing to identify bottlenecks. For critical services, multi-region deployment ensures resilience. Describe a time you mentored junior engineers and how you ensured knowledge sharing across teams. At my last company, I organized weekly tech talks and code reviews. I paired with junior engineers on complex tasks to guide them through system design and debugging. I also wrote documentation and created hands-on exercises to help them learn new technologies like Flink and Kafka.
