Bio
Jude Hirman (PMP, CSP-SM)
Aside from John's advanced technical skills, he is also an enthusiastic and engaged team player, always ready to help. There is no problem too big or complex for John to deep dive into and find the best solution to resolve them. He is excited to learn new technologies, and does so quickly, and critically analyzes how he can leverage his newfound knowledge to add more value to the organization. He's an exceptional leader who intentionally or unintentionally helps everyone around him get better at what they do. He's a rare and incredible asset to any team and I'm fortunate to have had the chance to work with him.

Achieved this by continuously gathering logs and metrics from Apigee and AWS API Gateway and computing metrics on the logs by using Kinesis, Kinesis Analytics and lambdas. - Trained colleagues on how to design and build cloud native applications in AWS. - Built and managed several internal APIs using Node.js, AWS Fargate, Code Pipeline and CloudFormation to help enable TR’s API strategy.
