We've decided that we will not define a list of tracks upfront, rather open up the submission to any topic. Later on we will choose the best sessions and sort them by topic relevance, so that attendees would be able to focus on tracks and room.
This means that we want submission on any topic that may interest developers, product folks, UX etc. Topics might include startups, mobile, web, devops, data processing, scaling, programming languages, api design, data science, gaming, computer vision and more... This is not a closed list, it's just to give ideas, if your topic doesn't seem to fit here and is of general interest, we want it!
