design + nerd · since 2007
I build things with software
and write about all of it.
Hey, I'm Dipankar. This is where I think out loud about AI agents, self-hosted infrastructure, DevOps, and the odd deep dive nobody asked for. Two decades of shipping, one very long-running blog.
What is desinerd?
A working notebook, kept in public for 18 years.
Desinerd — "desi" + "nerd" — started in 2007 as a place to write down what I was figuring out. It still is. Early posts are Django and Nginx tutorials; recent ones are about Rust CLI tooling and AI agent infrastructure. The throughline is the same: build something real, then write down what actually worked.
These days I run Neul Labs, building high-performance AI agent infrastructure in Rust. This blog is where the side-quests and the lessons that don't fit anywhere else end up.
More about me →- AI & agents Building, running, and reasoning about LLM-powered systems.
- Self-hosting & DevOps Home labs, ARM servers, CI/CD, containers.
- Open source Rust CLIs, contributions, and tools I actually use.
- Startup war stories Two decades of shipping, the honest version.
