I am a system architect at a web development company and at the same time, I work with an architectural design team as a CAD 3D developer.
I am 23 years old and finished my B.Sc. Computer Science last year, while working.
Two heavy jobs at the same time what saves me from making mistakes, is the ability to teach myself new things and be ready for new situations.
Dealing with three languages (not including programming languages), helped me to learn that most of the time, there is one logic and concept behind many wisdoms that look different and apart from each other. So if one understand the universal logic and ignores the language that is delivering it, he/she can be a valuable part of any team and handle the diversity of knowledge with ease.
It really makes me glad to be in touch with other people who are taking their life seriously, trying to enhance their knowledge and abilities.
