~ Important Notesat the beginning ~~~

At the very beginning allow me to write this note to recruiters, team members, decision makers and others, who are going to read this CV of mine.

With nearly three decades of experience across IT, software development, banking, insurance, logistics, and education, I have condensed my career into a clear summary highlighting the most relevant skills, technologies, and results. My goal is to help you quickly recognize how I can add value to your team.


So, with having that in mind, rest of this CV is simple summary of my previous experiences. So each page below is experience for that particular role I did in that particular company. Each with the 3 simple sections: Key responsibilities, Technologies I used and Accomplishments I did. Simple as this. A current one you currently reading is my own summary of my self, list of my core skills and contributions I did to the society so far. If interested to know more, there are the pages with details about all my previous professional assignments.

I wish you a great day, and hopefully you will have a perfect role for me and decide to meet me in order to talk more, and eventually hire me.


~~~ Summary - myself, about me ~~~

  • I consider myself a lifelong learner. While I have mastered all 7 layers of the OSI model, I approach every challenge with humility and curiosity.

  • Need to say that I am self taught, about all of these topics. Never had a teacher in any of these technologies and tools we use everyday.

  • I can quickly and systematically identify technical issues across an organization with minimal input.

  • I never critique work without providing constructive and actionable solutions.

  • Strong motivation to keep everything ultra secured. SecOps freak. Why? To answer that question would require me to write a book or two.


~~~ Core Skills ~~~

  • Troubleshooting: There are dozens of teams, big organization, legacy and highly complex code bases, issues in the production and nobody do not know what to do? Call me, and by the end of that same day, you will have a picture of what is going on and what you could do next.

  • Programming: C, C++, Bash, Python, PHP, Node.js, Vue.js, Typescript, and many, many, many other programming and scripting languages.

Last but not least note: I do not do code testing on any of those various platforms, whiteboard code tests, etc, sorry but nope. But you can tell me what you wish me to do, as some sort of test tasks, and give me some reasonable timeline for it, and I will probably came back up with solution on time.

At the end some practical code and lines of mine:



BeautyfullApp – over the years I came up with my 10 liner base…
https://github.com/ebosnic/beautyfullapp

Avoid Repository, as it’s name said as bad joke, it is something we should avoid, those who understand the code, will understand the joke, and what I am suggesting human kind to avoid in huge circles, hopefully.
https://github.com/ebosnic/avoidrepo/blob/master/tryme.cpp

NMCRUD – Since they blame me as mostly php oriented, I do js stuff as well, in this case fully operational nodeJS API with MongoDB for small shop.

Documentation ? When they ask me about it, I show them examples like this one:
Documentation Example by n00b

That is how I do documentation part. Mostly ASCII for diagrams and + some paragraph or two of readable and proper English. But very usable and people say Thank you n00b for being good dude on documentation part. And then they send me some cookies.

This would be all, I hope you will have a chance to hire this hidden gem for the long term if possible, until my retirement, because I do not like to change seats so often any more. Thank you for your kind patience if you gone this far reading this resume, my tip hat to you and one big thank you.

Yours sincerely

Enes Bosnic aka n00b
