William "Matt" Rader

Frontend Engineer | AI Prompt Engineering | AWS Solutions Architecture

Kansas City, MO · 14 years

Frontend engineer with 15 years building user-facing software: data-driven marketing sites, large-scale games, enterprise platforms, and regulated data systems in healthcare and insurance. Two years in systems and DevOps engineering on federal healthcare contracts broadened that foundation into infrastructure and production reliability. Now back in React development with a focus on integrating LLM capabilities into product and establishing prompt engineering practice for my team. Currently building serverless architecture on AWS in Rust, working toward solutions architecture with generative ai sas the next step.

Experience

Living Resume and Portfolio Platform

in progress

Serverless resume and portfolio built in Rust on AWS Lambda. Server-rendered with axum and maud behind CloudFront, with git as the source of truth and Step Functions orchestrating publishing, scheduled content enrichment, and a visitor-facing interactive flow using the callback pattern.

  • Designed a publish pipeline where artifacts are immutable and keyed by commit SHA, making rollback a manifest pointer flip rather than a rebuild.
  • Used Step Functions for the workflows that are genuinely stateful, with a CQRS-style read projection so page rendering never queries execution state.
  • Built on a least-privilege, no-always-on-compute footprint.
