Eliminated performance bottlenecks by decoupling parts of a monlithic Node.js application into a microservice architecture Led the team to further advance decoupling efforts and educated junior developers on infrastructure best practices Set up monitoring and alerting across the system, to improve awareness of production issues

This was a very unique and cross-functional position, where I got to act in different roles depending on the need of the business. The points below are organized by the type of role that I took on (Developer, Scrum Master, and DevOps). DEVELOPMENT Worked on an innovation team with the goal of decoupling the existing monolith application (Websphere, Java 7 EE, DB2) into microservices using Kafka queues Improved performance of Ethoca Alerts by redesigning one of the legacy data processing components to use Kafka Streams. Load on the DB2 database has been alleviated by using Kafka topics to persist state, and architecture has been greatly modernized by following the streaming paradigm. Implemented additional security features within the logic of our Kafka producers and consumers, to adhere to contractual security requirements imposed on the business. DEVOPS Pioneered the company’s initiative of automating environment provisioning with Chef o Educated colleagues on best practices of infrastructure-as-code through demos and info sessions Orchestrated Kafka cluster setup through Chef Provisioning Actively supported team members by resolving deployment issues after hours to accommodate important deadlines; in the process, uncovered and fixed bugs not caught by automation testing Led team to use dedicated development environments on AWS EC2 instead of sharing an on-premise environment and conflicting with the work of other teams SCRUM MASTER As a Scrum Master, I conducted stand-ups, refinements, demos, retrospectives and sprint planning sessions as part of a 2-week sprint cadence Acted in both a DevOps and a Scrum Master role in a temporary team organized for 3 sprints to prepare infrastructure automation for a major release.
