Developing cloud native complex systems is a multidisciplinary challenge, combining frontend, backend and data plane components with a wide variety of devops and testing complexities. Dealing with these challenges requires a wide set of tools, languages, design methodologies and a solid delivery methodology. How do you establish a team and create a common basis for communication and culture allowing for successful integrations? In this talk we will overview our experience at Iguazio growing an R&D group from 5 to 75 developers in ~3 yrs, working with more than 5 (development) languages and distributed between multiple sites and time zones.
