In my job, we are taking this new regulation very seriously. :-)
We are building guidelines for POs and developers to respect the new GDPR restrictions on future projects and during development.
Also, we have to build an internal tool to erase correctly the user's datas of our system (on explicit demand only).
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
