Seth (Amekudzi) Mensah
@cerebrocerberusI build backend systems that hold under load and stay secure: distributed services, APIs, and the infrastructure beneath them. Outside work, I build open source communities in Africa. I've run Codetopia since 2020, and I maintain the projects that take new contributors to their first merged pull request. I write about what I build, break, and debug.
Experience
Where I've built systems and led the people building them. Hands-on engineering and technical direction, usually at the same time.
