Message

At Amazon Web Services - DynamoDB, I improved writer fairness from 35x to 1.2x under contention from 32K+ concurrent writers. I also built backend services processing 20M+ events monthly and developed CAOS, an LLM-powered investigation agent that reduced investigation time from approximately 60 minutes to 3 minutes.

Previously, at Oracle Cerner, I developed Java and Spring Boot microservices processing 100K+ operations per minute and built monitoring that reduced resolution time from 20 minutes to 6. At Rigbot, I developed NLP data pipelines and automated model training and evaluation; earlier, at Keystride, I developed backend services and optimized queries and caching.
