T-Mobile

2005–2015

T-Mobile firewalls and VPN gateways, configuration audit and synchronisation tools, and penetration testing.

Melody Target (2005)

In 2010 I carried out several rounds of penetration testing on T-Mobile’s VoIP infrastructure and produced findings reports with recommendations.

From 2011 to 2015, working as a subcontractor, I:

configured Cisco ASA firewalls (migration from virtual contexts to dedicated hardware, EIGRP towards PE routers),
developed a Python tool for analysing and auditing static routing on IOS/IOS XR firewalls and routers (including IPv6),
migrated VPN gateways from Cisco VPN 3000 concentrators and IOS to Cisco ASA, including migration of user accounts from LDAP and remote access via AnyConnect for both employees and handheld terminals used in logistics,
developed fistool for synchronising firewall configurations,
prepared and delivered a Cisco ASA configuration training course (2015).
