About Paul

I’ve been building software since 2012, from websites and reporting tools for small businesses to customer apps, payment integrations, and telecom platforms.

At Jamii Telecommunications, I work on customer apps, backend services, and network operations tools. At Lightup Networks, I work on VoIP provisioning and automation.

SimpleKraft is my independent consulting practice. Outside work, I’m usually out hiking or taking photos around Kenya.
