What I am most proud of (anyone can do, but not everyone does do)
- LDAP (OpenLDAP) : Authentication for system authentication (From simple web services to Linux, Windows, VPN, AWS Identity Federation)
- VPN (OpenVPN) : Uses VPN Server to access AWS Private resources, Uses same VPN to provide remote access for office.
- Jupyter (Jupyter Hub + Jupyter Lab) : When there is not enough time to implement a elegant web/desktop application, uses Jupyter to do a simple job.
What I do like everyone does
