For about one year I was working on biggest e-shops in Lithuania, created on OXID (e.g. steptop.lt, e-senukai.lt, imtymipagunda.lt, irankiai.lt, pex.lt, kompiuteriai.lt). My main responsibilities was supporting, bug fixing and creating new features. I was working not only on back-end, but also on front-end. I had a lot of performance related tasks, a lot of API integrations and Payments integrations. I have learned a lot about ecommerce and backend development in this position.
Afterwards I started to work in dedicated project teams which I have described below (Jankowfsky, Movinga).
I have worked as an team lead of 3-4 programmers where I had to teach juniors programing techniques and code review their code for couple of months.
Currently I'm working on the biggest Lithuania travel site where my responsibilities are bug fixing, refactoring old parts to the new-clean structure and implementing new features.
