New branding for my app screenshot generation site 🐋💦🤩 Founding members already getting access. Getting closer to the official open release every day!
Your GitHub history can look like this, and it’s ok. If you know you can do a job, apply. I've met so many great devs that weren't active on GitHub publicly. We need to understand that not everybody prioritizes side projects, for many reasons. And that does not invalidate them for the job, at
