Reference architectures, tools, and research substrates — the things I build alongside the writing.
A reference architecture for retrieval-grounded agents that actually ship to production. Includes the eval harness, the routing layer, and the parts I would not build again.
A map of the AI stack, updated monthly. Drag-and-drop layers, costed in real numbers, exportable as a Mermaid diagram.
A multi-model debate harness. Six models argue a question, a seventh judges. Used as a research substrate for a few of the essays here.
A small writing tool I use to draft these essays. Distraction-free, obsidian-friendly, with an inline LLM that argues back.
I'm Rijul. I write essays, host a podcast, and build small things on the web — all of it in service of one question: how do we leverage AI in the next decade without giving away what mattered in the last? New work lands here when it's ready. Subscribe and I'll send it once.
