Started as the technical lead for a team building Divvy's partner-facing web interface utilizing the existing monolith's GraphQL endpoint resolving over gRPC to a separate microservice which ingested SalesForce data via a Kafka Connector. Later planned the upgrade for this service to migrate from gRPC to instead use Apollo's GraphQL Federation.After Divvy's $2.6Bn acquisition to integration work, assisted with cross-authentication (SSO) implementation and various API integrations enabling cross-selling between Divvy and Bill.com.Joined the Platform Engineering team to improve engineer onboarding reducing the time it takes to fully configure a laptop from 1-2 weeks to 1-2 hours via automated, self-serve diagnostics that doubled as a troubleshooting tool. Engaged in streamlining the developer experience by converging the development platform into a single Docker Compose setup that seamlessly networked with "bare" services on the host with a single configuration mechanism using sops and KMS.Also built a Rust-based CLI tool with an easily-extensible lazy-loaded plugin system for engineers to more-easily build their own automations and tools that integrated with our authentication and authorization systems and existing tooling for interacting with other internal tools and APIs.Built a Deno service for collecting user metrics on the previously-mentioned CLI's usage patterns to show cost savings based on time and resource reduction.Helped upgrade across many versions of Kubernetes in AWS EKS and various services' Helm charts -- some vendored and some custom. Imported legacy infrastructure into Terraform with solid infrastructure-as-code (IaC) and modern GitOps best-practices.Conducted many product experiments including Pulumi as a Terraform alternative and ArgoCD as a replacement for a bespoke, pre-existing Consul+Helm deployment pipeline. Also implemented a cross-organizational event exchange bridging custom eventing systems, Kafka, and AWS EventBridge.
