Work History

Principle Engineer

SERVICENOW
San Diego, CA
07.2015 - 02.2023
  • Reduced user profile memory by 90% by mashing up of Bloom Filters and Clock plus adaptive replacement (CAR) cache
  • Implemented detection and remediation of memory leaks using piece-wise linear regression by JVM instrumentation
  • Categorized incident reports based on their short descriptions using Maxent Logistic Regression. Created model in Python and implemented in Java
  • Created Dynamic GraphQL that allows GraphQL schemas to be incrementally loaded on demand. Reduced footprint of schemas by 99%.
  • Created predictive model that given file changes predicted which integration tests are correlated to failures. Solved problem of not getting full regression runs for weeks.
  • Created super computer using Kubernetes to deploy InfiniBand in large GPU cluster.
  • Abstracted legacy database distributed cache to trivially allow any technology such as Kafka, RabbitMQ, etc as replacements
  • Invented stochastically realistic loading client to demonstrate real world horizontal scalability of REST APIs. Create profile by mining Splunk logs.
