Welcome Our Emcees
Let's give a warm welcome to our two wonderful emcees!
Backend engineer at Freeletics in love with Ruby elegance and simplicity since 2011. Passionate about testing, the people side of our industry, and building bridges between engineers and the business people. Rails Girls coach, tweeting as @KFMolli.
Valentin started programming in high school and participated in algorithm competitions. One thing led to another and he ended up doing Ruby for pleasure and profit for the last 8 years. Apart from the regular backend stuff, he has been involved in several machine learning and performance projects. He really enjoys peeking under the hood and making things faster.
