Mathematical background and scientific approach. Extensive knowledge in theoretical and practical aspects of computer science. Able to efficiently process large amounts of new documentation and get practical knowledge from these. Interested in creating testcases and benchmarks/measurements to check and study behaviour of computing system, as well as automation scripts to factor out repetitive tasks. Know a lot of engineering classic, can describe what could go wrong with this or that system/network setup and how to fix/improve hedge that.


Lazy. Like to think more, and type less. Prefer to find and reuse existing software/library/framework than to develop something from scratch. Prefer to choose highest-level language suitable for the task than to implement framework model again and again at low level. Prefer mixed-language programming with implementing only the most-demanding parts in low level langs.
Underdeveloped management and organizational skills. Tend to think in SouthEast-Asian manner and see overly big picture (don't hurry to fulfill an order, your commander might wish to cancel it) :>
