As a Distinguished Engineer at Optum I have the opportunity to work on projects and initiatives that span the entire enterprise. I am entrusted to leverage my skills and experience to formulate and deliver creative, effective, robust and secure solutions that drive our products and infrastructure.A large portion of my day-to-day activities are self directed and I generally focus on finding ways of “reducing friction” that our development teams may encounter. For example:- Implemented a low-code “event sourcing” stream processing service that enabled rapid construction of new data streams from event filters * Kafka * Docker * Go * Azure- Automatic secure proxying across network boundaries with strong identities and least permissions * Policy as Code ( Open Policy Agent - OPA ) * Layer 4 - 7 mTLS * Fully auditable for permission events and security needs- Presentation series about large scale software development practices- Workshops and presentations about how/when/why for distributed systemsThe other portions of my job functions are to support large initiatives around the UHG enterpriseExamples:- Helped Optum Connect line of business develop a strategy to rapidly onboard commercial enterprise customers for IT Outsourcing scenarios while keeping our costs in terms of human and infrastructure as low as possible * Designed creative, proprietary, solutions that enabled migration teams to treat “legacy” datacenter fixed clients the same as clients who may already be in public clouds- Created a framework that would enable Optum to transparently migrate from proprietary, on premises, databases to public cloud hosted OSS versions - Support the Advanced Technology Collaborative (ATC) * Architectural needs * Software development practices * Cloud security support * Hands on keyboard development * Engineering leadership
