Experience
Kinja/Gizmodo Media Group
https://kinja.com/As a DevOps engineer, I was a part of the team that designed and executed the cloud migration of Gizmodo Media Group to AWS. Sites run on Kinja serve ~10,000 requests per second and more than 100 million visitors a month. Everything in AWS on Kubernetes base.
Syslog-ng
https://github.com/balabit/syslog-ngSyslog-ng is an open-source logging engine that is able to process thousands of logs in a second. Besides the technological challenge that it provided I have learned what it is like to be a part of an open-source community on GitHub that interacts every day to make its product better.
Codie, the Robotic Toy That Teaches Kids Coding
https://techcrunch.com/2015/12/08/codie-is-a-fast-rolling-robot-toy-that-teaches-kids-progamming-concepts/?guccounter=1"A robotics company that teaches kids how to code, Codie Labs, took the stage at TechCrunch Disrupt London this afternoon to show off their fast, rolling and programmable robot, Codie, which is controlled via a mobile application for iOS or Android. The Budapest-based startup earned the opportunity to present on the big stage by winning the Wild Card position, which pulls a promising company out of Disrupt’s Startup Alley." (TechCrunch)
As the person responsible for delivering the software and infrastructural components for Codie, I had to sync teams working on different parts of the product. We had to be aware of the progress of the hardware itself and keep in touch with the people responsible for tracking the market and social feedbacks. It was a great opportunity for me to work under huge pressure and experience the beauty of creating something from nothing.
It's unfortunate, that after the first two waves of delivery, CodieLabs (the company behind Codie) was closed because of financial hardships and problems with manufacturing the robot.
