At 2500 transactions per second, this reduced timeouts by 99% and reduced p99 response time from 250ms to 160ms. * Implemented a feature to consolidate queries to Cassandra before executing, reducing overall load on Cassandra by 20% while not impacting response times. * Greatly improved our monitoring by adjusting our Kamon/Prometheus reporting configuration to more accurately represent our response times and provide more frequent metric updates. * Added various metrics to our Application logs being ingested into Elasticsearch. Using these metrics, Kibana Dashboards were created to allow for detailed performance analysis on live and historical traffic. * Created and extended detailed runbooks to handle PagerDuty alerts and various Maintenance procedures spanning across our entire infrastructure (k8s, Kafka, Cassandra, EMR, ELK) ◦ Became a primary contact point for new team members onboarding onto the project. Provided training and on-going advice on how to navigate/improve the system. * Managed infrastructure through Terraform modules and many Kubernetes applications. Changes included AWS networking setup, migrating resources from EC2 to Kubernetes, and rolling out/monitoring application deployments

The programs were from previous acquisitions, so the new application was built to support current business as well as easy setup of future acquisitions. * Defined a local caching strategy for API Requests from our Angular 8 application. Utilized NgRx to maintain application state and cache common request responses. By short-circuiting requests using cached responses, loading times during sustained use of the site decreased by 35%. * Established standards on the use of new report tooling that communicated directly with the database cluster. This included standards on writing stored procedures, designing reports using a standalone designer, and developing components to aid with end-user interaction. Developers new to the tool could then complete complex stories within 2 weeks. * Implemented a Job Scheduling system that utilized CloudWatch Events and Step Functions to trigger Lambdas across CloudFormation stacks. The approach was data driven to allow for easy configuration. An administration system allowed system admins to view and manage jobs from the Frontend, as well as schedule new jobs. * Implemented an Event dispatching service to filter and relay incoming messages using DynamoDB, SNS and SQS. Compared to the legacy system, this allowed messages to be accepted, transmitted and consumed on an on-demand basis instead of a scheduled basis. * Actively mentored our Interns on a foreign technology stack to ensure success in their time-constrained project.
