I've built and improved high-volume backend systems at Amazon and Oracle, using Java, Spring Boot, AWS, REST APIs, and distributed systems. At Amazon, I launched a self-service invoice cancellation platform that eliminated manual effort equivalent to 4 FTEs annually and developed reusable components saving 4,500+ engineering hours each year.
I've optimized database queries, caching, validation, and observability to reduce latency, improve throughput, and lower Sev-2 incidents. I also build distributed services, including a Java and Redis URL shortener, and have applied CNN, RNN, LSTM, and Bi-LSTM models to sentiment analysis.
