synlab laboratory network

2008–2022

For fourteen years I managed and developed the network, VPN and monitoring infrastructure for synlab czech across dozens of sites.

As a subcontractor to CNS, I designed, configured and maintained the network for synlab czech, covering their Prague head office and server rooms through to branch offices in Brno, Plzeň, České Budějovice, Chomutov, Znojmo and other towns.

Cisco Catalyst switches (VLANs, EtherChannel, DHCP snooping, SNMPv3), IOS upgrades, network redesigns at the head office and Brno branch, new server rooms (2012–2014),
Cisco ASA firewalls and their migration to new models, DMZ for mail and FTP servers,
site-to-site VPN to partner laboratories and the German head office, VPN to Azure for Office 365, remote access via AnyConnect with RADIUS authentication,
Wi-Fi for staff and guests with 802.1X authentication,
working with Vodafone on the branch offices’ migration to MPLS, including QoS and bandwidth shaping,
centralised logging with syslog-ng and its use in investigating security incidents,
monitoring in Nagios and NagVis, configuration archiving in RANCID, custom check scripts,
performance measurement and analysis of the laboratory application across the Czech and Slovak networks (2014–2016).
