Top SchoolEgon Hilgenstieler is a seasoned technology leader and co-founder serving as CTO of Focus NFe, where he has spent over a decade building APIs that simplify issuance and management of tax documents across Brazil.

He began his career in enterprise support and co-founded a custom software shop before moving into education as a visiting professor, giving him rare experience in both industry delivery and teaching complex topics like algorithms and numerical methods.
