Metrics API

• Decoupled monolith pipeline application into 8 micro-services and redesigned and implemented a database configuration driven pipeline allowing services to be independent from each other and database configurable based on rules.

• Decoupled 8 microservices lifecycles and improved team velocity by introducing Jenkins pipeline and saving hours of idle developer time by decoupling builds.

• Designed and implemented new Reporting APIs for querying Druid and Oracle using SpringBoot, Vertx, Docker, Druid and Oracle allowing business to deliver strategic feature.

• Replaced nightly ETL survey scoring and provided customers with near real-time analytics on surveys by designing and implementing survey scoring within the Big Data pipeline using Vertx, Kafka, DCOS, LinkerD and Cassandra.

• Set up monitoring and alerting for new micro-services services as well as maintaining existing ones using Prometheus and Grafana.

** Skills: Java, Vertx, SpringBoot, DCOS, Kafka, Cassandra, Druid, Oracle, Docker, Jenkins, Prometheus, Grafana

Replay V2

• Architected and lead the effort on Replay V2 from the data-ingestion to the workflow orchestration for movie production.

• Designed and implemented Replay V2 movie production and replaced legacy C# applications producing 15k movies per day by introducing Serverless architecture using AWS Step Functions, Lambdas, S3, NodeJS, Express, Puppeteer which resulted in saving $200k per year in AWS cost.

• Improved stability of the data ingestion and reduced AWS cost (Redis, EC2, S3, SQS) by $60k per year by replacing legacy C# applications using C#, Redis, AWS SQS, EC2, S3 and NodeJS.

• Led the effort on Replay Continuous Integration pipeline using Jenkins, Ansible and AWS CodeDeploy improving Development velocity by 50% and reducing proneness to error in production deployment.

• Reduced AWS cost by $70 per year by implementing new Application design in new AWS account and migrating old components from old AWS to a new one reducing cross-region and account data transfer.

• Dockerized the development environment using Docker and LocalStack which resulted in reducing AWS local development cost to 0$ and improving Development Velocity overall.

** Skills: Java, Vertx, JavaScript, NodeJS, Express, Mesosphere DCOS, Druid, Cassandra, Kafka, Zookeeper, Redis, Step Functions, Serverless Lambdas, EC2, S3, SQS, Marathon, Microservices, Service Discovery (Linkerd, Eureka), AWS API Gateway, Docker, LocalStack, Monitoring (Prometheus, Grafana), Maven, CI-CD (Git, Jenkins, gitflow).
