I have experience of +10 years in development.
I worked over projects with different stephens difficulties. I have experience with different frameworks: Kohana, CodeIgniter, Yii, Yii2, SlimFramework, Laravel 5+. I am started with PHP 4 and use PHP 7+ now. Also i have experience in native JavaScrpt and used VueJS. In addition i have experience Team Lead 3+ years. There were situations when i worked on many projects at the same time. I did not experienced difficulties when switches with primary project to second project. Anyway i love worked wit one project since we haved best results. There were situation when i used skills of DevOps. I used AWS, Docker, Gitlab CI/CD. I am do not afraid difficulties or overtimes but i try do not allow they happen.
