Expert in: Perl, SQL, C + 3 more
My first computer – a TRS-80 with 4K (4096 bytes) of memory – sparked a lifelong journey with technology. Since then, I’ve worked with nearly every platform imaginable: Apple IIs, Commodore 64s, Amigas, VAX/VMS clusters, MVS mainframes, Unix workstations running Sparc, Solaris, AIX, and IRIX, as well as Macs and PCs. I still have my childhood Atari 2600 and Commodore 64, along with the 300-baud modem I used back in the day. I’ve been a “Linux as a desktop” user since the 1.x kernel series (1996); before that, I was an OS/2 user. Over the years, I’ve had the privilege of working alongside some of the great minds in the industry: Larry Wall (Perl), Tim Bray (SGML/XML), Dan Bricklin (spreadsheet), Ingy dot net (YAML), Tim Killeen (webring), Tim Vroom (Slashdot), and others. I even have a photo of my mother standing with Vint Cerf. My LinkedIn profile includes a recommendation from Audrey Tang, Taiwan’s first Minister of Digital Affairs. Code I’ve written has shipped as part of every major operating system – and even made its way into outer space. My contributions have supported projects such as the Human Genome Project, and if you’ve ever opened a JPEG, watched an MP4, or unzipped a file, there’s a chance my code helped make that possible. Apache modules I authored were discussed in "Hardening Apache" and recommended at Defcon. I’ve worked long enough with several organizations to see projects through their entire lifecycle – from greenfield development and rapid growth to maintenance and deprecation. More than once, I've designed and implemented new systems to replace legacy software I originally wrote years earlier I’ve been using Git since before GitHub was born, and have also worked with Subversion, Perforce, Mercurial, and even CVS. My work has been published in Forbes, OS/2 Magazine, and EDM/2, and documentation I’ve authored has appeared in O’Reilly books. For more than 25 years, I’ve operated as a remote-first professional – long before it was mainstream. I have the discipline, adaptability, and communication skills to collaborate effectively across time zones (and the old long-distance phone bills to prove it). Some see me as a dinosaur in the industry. They imagine that I am a man in his early 50s who is over the hill. Others see me for what I really am – a seasoned professional whose depth of experience and technical insight continue to drive meaningful results. I’m now looking for an opportunity to bring that experience to an organization that values expertise, craftsmanship, and the ability to turn complex ideas into lasting, impactful solutions.

I am Markus Wernig, an IT professional with over 20 years of experience in enterprise IT projects. I have got a very broad background and experience in IT, which ranges from software engineering to network security and system engineering/administration. For over 15 years now I have worked primarily in software engineering, from full-stack to appliance, from network automation over PKI and cryptography to database-heavy workflow applications. Before that, I was mainly active in network security. I have worked alone and in agile team settings. As lead engineer I am comfortable comunicating on executive levels as well as with technical staff and end-users. I am not, however, a typical 100%-only-developer. Based on my extensive experience in various fields I would describe myself rather as an allrounder with a strong suit in software engineering and security . Here are some of the technologies I have a work record with: Java/J2EE, SQL, Angular, Kotlin, HTTP, SOAP, X509, S/MIME, REST, Perl, PHP, JSON, Spring Boot, Firewall, Checkpoint, Forcepoint, VPN, Proxy.
