After his first child was born, Matt Wonlaw (@tantaman) imagined giving his son life advice. What kind of life did he want his kid to lead? At the time, he was working for Facebook, and he decided that his own life needed a change in direction. So Matt started vlcn, aka Vulcan Labs, a research company that develops open-source projects like CR-SQLite and Materialite. vlcn has an unusual business model – Matt receives donations and sponsorships from users and clients. It’s all part of his mission to rethink the modern data stack for writing rich and complex applications. Contributor is looking for a community manager!

Amplication is an open-source development platform for scalable and secure Node.js applications. It allows engineers to skip writing boilerplate code and offers the flexibility to customize and add components. Amplification was created by Yuval Hazaz (@Yuvalhazaz1), a veteran developer who determined that low-code platforms save time but restrict freedom. Instead, Amplication uses code generation to reliably and consistently build robust production‑ready backend services. Contributor is looking for a community manager!
