Lukas Rosenstock

Lukas Rosenstock is a freelance entrepreneur who supports both startups and large organizations around the API lifecycle as a consultant, software developer, and technical writer. He lives in the heart of Europe in Germany. Lukas is a weird German who doesn’t like beer and a weird person in tech who doesn’t drink coffee, though both are adequately replaced with tea. When he isn’t busy with APIs or coding, he enjoys board game nights and thinking how to improve the world with effective altruism. Feel free to follow @LukasRosenstock on Twitter.
