Jeremiah Ajayi

I'm Jeremiah Ajayi. I make software, mostly backend systems, infrastructure, AI tools, and products that run on the internet.

I currently work at Chatarmin, where I help keep the product reliable as it grows and shape the technical foundations behind the systems we build. My work spans backend engineering, infrastructure, databases, distributed systems, architecture design, reliability, integrations, background jobs, and the systems behind ecommerce communication, marketing automation, customer data, and AI-powered workflows.

A lot of the work is invisible when things are going well. That's usually the point.

I also run Anonn, a small product company for the things I build on my own: Beep, PDFly, FinAI, and other experiments.

This site is where I write about what I learn while building.
