DATA & AI ENGINEER

I build data platforms, and the AI agents that run on top of them.

I'm Duyet — a Senior Data & AI Engineer. I spend my time on the load-bearing parts of software: pipelines that move data at scale, platforms that stay calm under pressure, and the agents and tooling that make them genuinely useful. I like systems that are simple to operate and honest about what they're doing — and I open-source most of what I build.

Deep in vibe-coding mode — most of what ships here is written alongside coding agents, with me steering.
