Working as technical lead rotating between five departments to aid in executing their highest priority projects.Worked on a federation platform to allow access to internal tooling to Comcast's business-to-business customers. Helped build a collection of React components that provided shared authentication, authorization and navigation across multiple disparate existing applications so that they appeared as a cohesive single app to customers. Built a performant backend in TypeScript and gRPC to support that service.Currently, I'm working on expanding an existing Kubernetes platform built on RKE2 to support teams onboarding to move on-premise for cost savings. This work has included building improvements to its GitOps model, building and configuring clusters using Istio and Argo Rollouts for a safe, incremental deploy strategy, and training teams as they onboard to Kubernetes in general.

Increased Comcast's market share by deploying microservices and APIs in JRuby to support third-party cable companies. These services allowed third-party companies to use Comcast's device and account management services without rewriting any of the existing services. This initiative included building a new JWT authentication and authorization service, a translation layer API to ensure tenant data was kept separate, and a caching layer using Couchbase to improve performance. This smooth and efficient move to multi-tenant services allowed the company to nearly double their customer base.Built a prototype for controlling video playback between mobile devices and streaming devices. Wrote a mobile JavaScript application for the user interface and an XMPP-based backend for receiving the and processing the playback commands.Built a Rails application to monitor the health of microservices, shape traffic between them, and update their configurations.
