Andrew Possardt is a web developer with 9 years of experience building maintainable, high-performance full-stack applications using C#/.NET Core on the backend and React/Redux on the frontend. He has repeatedly served as the sole dedicated front-end engineer, leading rewrites, creating shared component libraries, and establishing coding standards to improve consistency and velocity. His work spans building design systems with Storybook, TailwindCSS and Rollup-bundled private NPM packages, to backend migrations from legacy .NET to .NET Core microservices and Stripe-powered billing migrations for tens of thousands of users. Comfortable across the stack, he also implements OAuth/OpenID flows with IdentityServer4 and leverages Docker and Kubernetes for deployments. Based in Denver, he combines pragmatic engineering with a designer-aware approach—often partnering directly with UX to turn components into reusable systems.
