Jan 2025 - Current (1 year 9 months)

• Worked as a full-stack developer, DevOps Engineer, and Product/project manager on a small application that supported United Healthcare’s small business sales team. The app was built a few years earlier by another team, but had severe performance issues, which prevented its adoption. My job was to figure out how to increase app performance.
• Did this by migrating the app’s NextJS frontend and Python/Flask backend deployments from our company's private cloud instance to GCP. This means I created the new GitHub Action’s CI/CD pipelines, Chainguard Docker images, and Kubernetes deployment files needed for each deployment.
• Implemented a couple of infrastructure migrations, which aligned our application with the enterprise’s cloud

• Worked as a delivery lead, and server-side developer, for a web app that’s used by brokers, who sell our small-business segment health plans, to check the status of their customers’ installation into UHC’s system.
