Senior🎓
Top SchoolJan Tomášek is a seasoned Platform Engineer with 20 years of experience building and operating Linux-based infrastructure, identity systems, and certificate authorities. He led technical implementation and long-term operation of national-scale federations like eduroam and eduID.cz, and helped evolve a CESNET CA from an offline OpenSSL setup to an online HSM-backed service. Deeply rooted in open source and Linux since university, he combines hands-on administration with development skills (Perl, C, Delphi) and a strong background in LDAP, PKI, SAML2, RADIUS and TACACS+. Jan’s career spans low-level instrument control and protocol reverse-engineering to scalable authentication platforms, showing unusual breadth from MS-DOS tooling to modern HSM-backed PKI. Based in Central Bohemia, he brings pragmatic, security-conscious engineering and a long memory of the Internet’s early days that informs robust, interoperable system design.
