About

Tristan Greeno is a highly skilled software engineer with over 5 years of experience at Experian, where he has developed new products as part of the company's innovation initiative. He is proficient in a range of technologies, including Java and Spring Boot, C# with ASP.NET Core, and JavaScript (React and Redux). Tristan has experience in containerization with Docker and OpenShift, which makes resource and load management easier. Throughout his career, Tristan has taken new products from ideation to maintenance handoff, redesigned existing monolithic applications into a scalable microservice architecture, and written internal tooling with libraries and applications. He has worked on over 6 different products in teams ranging in size from 5 developers up to almost 30. Tristan is passionate about software development and is always looking to learn and grow. He reads several books about software development topics in order to deepen his knowledge and tackle difficult problems in the industry. He fosters an environment where team members can reach out to him with any questions and ask for personal guidance on topics they need help with. At Experian, Tristan has led the design and implementation of microservices in an event-driven system that interfaces with an Apache Kafka data ingestion pipeline to orchestrate events, intended to process over 10 terabytes of data from customers daily with MongoDB and SQL Server as data stores. He established coding standards for the team that achieved over 95% code coverage across applications and a 70% reduction in new bugs. He also introduced an application design process that helped the team more than double its sprint velocity from 140 story points to over 300 after the team began to fall behind schedule. Tristan transformed monolithic VB.NET applications into modern C#/ASP.NET Core microservices for a legacy product that is a multi-million dollar revenue generator for Experian. He refined the software development process by teaching best practices, test-driven development, behavior-driven development, and design to over 30 team members. He laid the foundation for microservices by creating over 20 deployment and build pipelines using Octopus, Bamboo, OpenShift, and Docker. Tristan studied back-end development, focusing on Java and Scala, at The Iron Yard. He completed individual and collaborative projects using Java frameworks such as Hibernate and Spring, as well as Play, a Scala framework. He worked in an Agile environment for project tracking and management and utilized GitHub for version control. He holds a Bachelor of Science degree in Finance from Penn State
