About me

I am a certified Magento developer (backend and frontend) with over 5 years of professional experience working on e-commerce platforms for big organizations. I also have a Master of Science in IT (Computer Systems, IT project design, and management). My primary goal is to use technical skills and experience to deliver customized solutions that will allow my clients to gain business results. In most of my recent jobs, I was responsible for the modernization and maintenance of e-commerce systems. Some of them were handling up to SIX HUNDRED CONCURRENT USERS. From this experience, I have learned the importance of following the best programming and development practices.
