Aleksandar G. & Techy World

Writing about technology and us, immortal developers

There is no end to education. It is not that you read a book, pass an examination, and finish with education. The whole of life, from the moment you are born to the moment you die, is a process of learning. - Jiddu Krishnamurti

Polyglot software developer with wide spectrum of IT branches under my belt. Besides web development, I'm very passionate about C++ and languages based on C programming language.

Aside programming, I'm passionate about virtualization and computer networks and successfully working with micro services and docker containers from very early beginnings. I'm extremely passionate about my work and I spend a lot of time continuously learning, trying to stay up to date with all the latest technologies and trends.

Before everything, I always seek for working with good and humble people in an environment where we can learn from each other and continuously progress.

I'm passionate about teaching and mentoring others and I find no bigger joy than seeing my students getting jobs and praising me for that. Mentoring has helped my career kick off a lot faster and made me very technically articulated and expressive. There's no better way to stay up to date and stay sharp than sharing your knowledge and teaching others. Besides mentoring, I often do some live programming and blogging.

To end this humble summary, I'd like to share two of my favorite quotes that describe me as a developer.

"Programs must be written for people to read, and only incidentally for machines to execute." - Harold Abelson, Structure and Interpretation of Computer Programs

"I like my code to be elegant and efficient. The logic should be straightforward and make it hard for bugs to hide, the dependencies minimal to ease maintenance, error handling complete according to an articulated strategy, and performance close to optimal so as not to tempt people to make the code messy with unprincipled optimizations. Clean code does one thing well." - Bjarne Stroustrup, Clean Code

What did you work on, Alex ?

Keep in mind that I'm always trying to keep my CV more or less relevant, therefore, I often modify it in a sense that if some technologies or experiences become irrelevant, I will simply remove them from here. I will keep those that I find relevant for the positions that I might be interested in. I've been in this industry since youth, I don't think I even remember everything I did past 10 - 15 years.

The entire project was built with performance and optimization in mind, along with the goal of increasing the organic search, ease of maintenance and everything else that could bring more revenue and increase conversion rate. One of the metrics I achieved doing such optimization was getting the website from 6+ seconds average load time (when I joined the company) to below 3.2 seconds, which is faster then 98% of the website world wide.
