I made my first website in 1999. Since then I worked in nearly all parts of e-commerce: from frontend, through backend - with a detour to embedded development - to system administration. I believe in optimization, Open Source and Free Software, and to research the best, existing solution for a problem.
Working on infrastructure security, maintaining on-premises and cloud deployed vulnerability scanning and reporting systems, collaborating with external contractors for penetration tests, and internal security analysts.
Since early 2015 I'm working on automating Hadoop clusters with over 2000 physical nodes. I've refactored many of our legacy bash autonomous scripts that covers patch management and self-healing to handle exponential growth and to align with compliance requirements. I worked with SAP and HP to support user and hardware issues.
In 2014, I worked on monitoring, aiming to replace nagios, to reduce on-call alerts, and increase automation. Solution included adding self-healing processes to individual nodes, and preparing work for centralized logging.
Until mid 2014, I worked in communications, maintaining mail, fax, and proxy services. I migrated the former proprietary virus and content filtering to open solutions.
I was introducing and supporting external partners to use the company stack of load-balanced web- and database clusters, PHP and Java frameworks to develop iOS and Android based games.
I was part of a project porting an embedded code base to be interfaced with C# under Windows for Siemens.
I was developing, testing, and documenting time- and safety critical, hard real-time, automotive C software and deployed continuous integration for code quality metrics.
I maintained, upgraded and migrated - both in team and alone - high availability web- and mail services for the market leader real estate search engine in Hungary; occasionally helped with back office and Windows support.
I maintained Windows and Ubuntu machines and deployed an operating system imaging service with Finnix and PXE that could cope with slow networks. I regularly held classes in basics of C, atmel, embedded, and web programming, and kept some university WordPress sites running.
Specialized in embedded systems and industrial system automation. Awarded with Thesis Award from Budapest and Pest County Chamber of Engineers in 2009.
I used to make web presence for small companies between 2003 and 2010 on a custom PHP CMS. I moved to WordPress in 2007, wrote a few mildly successfull plugins for it. I ended up writing a simple static site generator in Python 3 to learn it, and to integrate Indieweb building blocks into it. I can write HTML and CSS by hand.
To keep myself up to date with technologies out of my day job I kept running bare metal servers for web, mail, XMPP, and ZFS storage services.
I'm an active practicioner of martial arts and archery .
