Practical AI engineering for real workflows
havyai is where I write about the engineering behind useful AI systems: agents, context, tools, memory, and the workflows that hold them together.
I share field notes from what I build, the failure modes I run into, and the tradeoffs that change the result. It is for builders who want practical detail without the hype.
