Top SchoolHendrik Schalekamp is a founder and seasoned software architect with over a decade of experience building Node.js and TypeScript-based products, mobile apps, and cloud-native GraphQL/GCP backends.

He has held CTO and VP delivery roles, scaling delivery teams and improving software processes across SaaS and mobile platforms while also operating as a freelance architect for internal enterprise projects.
