Summary
Willem Ruys is a pragmatic full-stack software engineer with 7 years’ experience building scalable, production-grade systems across healthcare, e-commerce, and agency platforms. He combines strong backend expertise in Node.js, TypeScript, Go, PostgreSQL and AWS with hands-on experience in search and integration problems for regulated environments like eQMS and hospital systems.
