I graduated from the Faculty of Technical Sciences, Novi Sad, in 2014, with a degree in Applied computers science and software engineering, defending my bachelor thesis “Fuzzy C-means clustering in CV -Pattern Recognition in Medical Diagnosis“. Throughout my education in the field of software engineering and computer science, I have discovered that the field I find the most interesting is the field of web development in combination with HCI (human-computer interaction). I have developed it as a competency, and I have a great desire and a goal to improve my knowledge and skills in this field.
Last 5+ years my field of interest is web development based on CMS platforms- WordPress Expertise!
I have strong background in web development and experience of successfully designing a websites layout, usability and appearance.
Over the last few years, I’ve had the opportunity of working for several web dev companies,
this has given me extensive web designing knowledge and technical skills.
Beside that i am obsessed with Web security and malware prevention on web, and proof oof that is more then 300 websites successfully cleaned and protected.

I strongly believe that, in the contemporary world of IT, this area has become a practical necessity, as much as a perspective.

There is a big difference between selftaught developer in web development and university degree engineer.

"Stefan is our man when we need someone do the work on wordpress websites, CSS, PHP, HTML, jQuery, ... He did several tasks for Neparno 10 so far and we are very pleased with results. He is honest, skilled, fast and hard working."
"Stefan was very professional, detail oriented and provided additional expertise in completing the project. He was responsive and communicated expectations and provided updates in timely manner."
Stefan is fantastic. I would recommend him 100% to complete a job for your. Not only did he transfer my website to a new domain as requested he also completed a couple of other minor tweaks without being asked. He is a great guy who works very quickly, and had me up and running on my new site within a few hours.
Stefan completed this job within an hour and at the price stated. The work was completed brilliantly, and got my website online with a matter of hours when I was worried I would no longer be able to continue with it. Stefan is polite, responds quickly to messages, and delivers a good end results. Would recommend and be using again. Thanks Stefan!
"Stefan was a pleasure to work with. He was fast, precise, and made additional recommendations that improved the outcome of the project. Will be hiring him again in the future."
Stefan was excellent to work with on my wordpress project. I had some basic specifications and he worked quickly and efficiently to get the job done. Any questions or changes I requested he delivered straight away. Highly recommended.
I am totally blown away by Stefan's expertise, professionalism, open communication and quality of work. He is an asset to any business and has done a fantastic job beyond my expectations. I will recommend him to anyone looking for an excellent freelancer. A five star job
Stefan did a great job with my website- optimized its speed and its now loads super fast (like 4 seconds) besides - he gots great communication skills - and is a very hard worker! Thank you for all of your help! I appreciate it
Stefan is responsive, energetic person, that accepted all the comments I had, and corrected them immediately. I am highly recommending him as WordPress professional. http://www.bizzbeesolutions.com/
I was very Happy with Stefan. The project was completed ontime and successfully. Another developer tried before him but could not get the bug fixed as he did. I have used Mr. Lanchushki to fix many bugs in the website over the years, all done professionally and sucessfully. highly recommend http://www.dccosmetics.com
Stefan is fast, knowledgeable and enthusiastic. Recommended!
"I was so impressed with Stefan's speed and ability to get this project done! He went far above and beyond what I asked by fixing bugs in my site that I didn't even know where there. I will absolutely be using him again! Stefan communicates so well and always delivers quicker than I expect. This is my second time working with him and won't be the last!"
"Stefan is a serious, responsible and committed worker, who does not look at the clock when the need to reach your goal always with high levels of excellence. I strongly recommend him."
Stefan is really top quality professional, very skilled and strong know how with design, front end, and Wordpress. He has gone beyond our expectations in speed, efficiency, reliability, quality of work. We will definitely hire him again.
"I have recently established my own company in the domain of HR management counseling as well as psychotherapy. Making a website like this was a challenge from the start, because it had to meet very specific preferences for the clients/web site users. Stefan helped me a lot to turn my ideas into website reality. He is a good listener, and we were able to connect. It was very easy to transfer my ideas onto his work, but not just that, his suggestions with the website helped a lot and i accepted them. He explains things in a simple way so that a person not from the IT world can understand them. He was flexible and always there to meet my needs while we were working. I give my best regards and recommend his services if you want to make a website. Very professional yet friendly and communicative. Thank you Stefan for helping our company make a brilliant website"
Stefan was a great programmer to work with. He skills are top notch. His communication was very good. I will definitively hire him again! Thanks!
"I used to manage my websites myself, but during the years Wordpress became such a burden, I would not be able to do it anymore without Stefan's help. Cyberattacks made my business very difficult at moments. Now, I have less sleepless nights and avoid security issues in general. Also changing trends demand up to date website design, which is a profession in itself. I could not possible have sufficient time for both beside managinf my company. I am absolutely satisfied."
Thank you for fast and efficient work!
Stefan is great to work with and helped me quite a bit with a couple website design projects. I would hire him again.
I can't say enough about Stefan! He quoted me a very specific number of hours for our project and arrived exactly on time and with perfect quality. I really look forward to working with Stefan on many more projects to come.
Stefan did an amazing job in developing our Wordpess website.
"Stefan is very friendly and pleasant to deal with. He did a great job on the site and suggested extra improvements. Great job and would definitely hire again."
Started right away. Understood the job thoroughly. Worked hard to complete it to a high standard. Very good communication by voice and in writing.
"Second job together completed flawlessly, we have now hired stefan as a full time Dev, cant recommend highly enough after using many freelancers in the past" "Probably the best freelancer i have worked with. Great pricing, exceptional knowledge, and was able to complete a task 3 others failed at. Have already given him our next project."
Stefan did an excellent job on this project, and I would definitely hire him again or recommend! He was very available, there was no language barrier to communication, and he followed instructions to complete the work quickly and without issue.
Extraordinary professional! Great developer, would recommend.
Stefan has been an absolutely fantastic web developer! He is super fast, follows instructions well and even gives useful advice when it is needed. Even with some complications and delays with this project, I couldn't ask for anything better from a freelancer. Top hire!
Fantastic freelancer. Fast, efficient and produces quality work. Very patient too when I had issues using upwork! Recommend highly, you will have no worries with this freelancer - he's fantastic.
Highly recommended Wordpress freelancer. Quick reply and gets job done quickly.
Stefan is brilliant. This task challenged him, but he hung on and stayed on it until he resolved it. Well done Stefan http://www.abcbuildinginspections.com.au/
Stefan did an awesome job at shortly notice. Would hire again and recommend. Thanks.

Amazing freelancer, creative ideas and attention to deadlines is top level! Working with him on other projects.
Stefan was in charge for building our new e-commerce. Once we have chosen the template among several he proposed, Stefan had no problems in adding special requests/changes creating in this way a perfectly tailor-made UX. He also had a great attitude towards the job, he always responded promptly and on time. Very well organized making our remaking easier and smooth. Thank you Stefan
"Stefan, I would like to keep the job open to stay in contact with you. Your website and client list are impressive. You were fast and efficient. Thank you so much for your work."
Stefan is an extraordinary young man who works fast and perfect. Thank you for making my dreams come true! I hope we will work together in the future and move some new boundries in web develpoment. It was pleasure to work with you.
