ABOUT ME

Javascript Developer at Toptal

I have extensive experience in systems analysis and development, considering the benefits they can provide based on your organizations needs and the premise of giving the best performance to any application.
I also have expertise working with the latest javascript frameworks like Backbone and Angular JS. Currently I'm teaching Angular JS lessons and doing consultancy on this topic.
My experience in web development allowed me to build fully functional web applications that scales and work in any browser no matter if it is a mobile or a desktop browser.
I love to create clean websites with very well organized javascript code.
Additionally I have experience in project management, and I had the opportunity to direct one based on the principles of PMI.
During my experience I have acquired working knowledge of warehouse, logistics, sales, accounting and quality management processes.
