I am a senior Software Developer with 20+ years experience in APIs and web applications for ecommerce, travel industry and other sectors. I prefer the backend yet im not afraid of frontends. I even can do DevOps, i would not call me a Admin though. I like open source, remote work, putting tickets to "Ready for Review", meetings in videochats across timezones, tagging releases, refactoring, writing tests, checking the commit log and posting smilies to the chat.
