- Developed a new personal lending backend system for the M1 Finance app. Leveraged an event-sourcing architecture with Scala, Akka, Kafka, EC2, SQS, SNS, and Postgres. Successfully released and originated millions of dollars in loans. - Integrated with 3rd party providers for loan lifecycle, payments, and origination. Established reconciliation jobs to assure consistency between systems. - Implemented event and schedule-based email notifications for the application and loan lifecycle sending thousands of notifications per day. - Integrated with a 3rd party identity service to verify the income of users, increasing the number of successful applications by 35%. - Established comprehensive documentation on the personal loans system and created processes to support it through alerts and on call. As a result, we were able to efficiently support the system during incidents and rapid growth.

- Lead team in the development of an Enterprise Event Tracking platform. Tracking billions of compliance records across multiple geographic data centers. Utilized Spring Boot, Kafka, Akka, Cassandra and DB2 to create a highly scalable, event sourced architecture, capable of correlating events and avoiding duplication of communications to customers. - Development of a Mass Communication Platform in OpenShift to replace the existing legacy monolithic services. Leveraged Spring Boot, Kafka, and Akka, alongside Cassandra and Oracle databases to create an event sourced architecture with CQRS. Achieved a performance of over 1 million SMS communications to customers per hour. - Mentored 3 junior engineers on Spring Boot, Java functional programming, Java Streams, Kafka, Spock and Kubernetes. Utilized paired programming alongside TDD and BDD to enforce topics. I received feedback from management that their productivity was increased drastically in a short period of time. Each went on to become senior engineers shortly after. - Taught over 20 classes across the organization on TDD, BDD and data-driven testing. I co-hosted an internal-Udemy course on the Spock testing framework that was recorded and is still utilized at USAA for training purposes.

- Worked on an agile team developing a new payments platform for USAA in Java, JBoss and Redhat OpenShift to replace the existing IBM Websphere monolithic system. Successfully released the system supporting millions of payments per month. - Developed batch jobs using Spring Batch to process thousands of ACH payments and NACHA return records per day. - Implemented the Spock unit testing framework, test-driven, data-driven and behavior-driven testing practices for our agile team, increasing our test coverage by 30%.

- Developed a new automatic property claims assignment system in Spring Boot with an AngularJS frontend and Google Maps integration. The system successfully automated over 90% of claims assignments, freeing up hours of time for each one of our claims managers. - Developed a new claims management system in Spring Boot and AngularJS replacing the existing legacy C# and ASP.NET system. As a result, hundreds of thousands of lines of code were simplified to only 20% of the original codebase, and unit test coverage was established.
