• Performance: implemented custom Spring multi-level clustered Redis cache; tuned application & infrastructure parameters e.g. Hibernate params, AWS params, pool sizes, TTLs; led load-testing & holiday shopping season preparedness efforts supporting 5x throughput
• Reliability: pushed for automated testing e.g. data-access testing, controller-level testing; upgraded core libraries & runtime e.g. Spring 4, Jetty 9, Java 8; set up metrics dashboards & alerts on AWS CloudWatch, StackDriver, & SignalFx
• Infrastructure: implemented multi-tenant TLS termination using HAProxy with SNI; led experiment to use SPDY protocol; implemented application-level rate-limiting; set up Graylog/Elasticsearch cluster
• Technical design: investigated & reported on techniques & paradigms such as the actor model, reactive systems, CQRS, event sourcing; implemented image resizing microservice with Akka HTTP/Streams in Scala, ImageMagick, Docker
• Developer productivity & education: wrote best practice documents, technical articles; delivered tech talks on testing, refactoring; evangelized Java 8 features; advocated functional programming style; engaged in 1-on-1 mentorship across teams; drafted syllabus for software engineering education

• Ensured systems were up & running, especially under load; led experimentation with Twemproxy for Redis clustering
• Measured system performance using JMeter, Bash, & Python scripts
• Identified, triaged, & addressed performance issues by code analysis, Java VisualVM, & SQL query analysis
