Reaktor Dev Day is a one-day, four track conference arranged by the creative technology company Reaktor. Back in 2010, we got tired of having so few quality tech conferences with international speakers in Finland. We then took the matter in our own hands, and this year, Dev Day will be organized for the fourth time. Did you miss the last year’s event or just feel like a rundown on some of the action? Check out the event photos, videos, speakers’ slides and the live blog!
