Examination office backend & portals
Public university, Bangladesh
The Rust backend and portals behind a large university examination office — students, teachers, management and payments.
What I built
- Rust services over Oracle with tuned connection pooling
- Student portal, management portal and public API behind a reverse proxy
- Payment gateway webhooks hardened at the proxy and in the backend
- Virtualised hosting with automated database backups
