Hi, I'm

Marcio Sete.

Founding engineer with 25+ years shipping products, teams, and companies.

Currently at Neu21, leading the AI Practice and helping Aussie companies adopt agentic engineering as an enterprise capability.

I'm also the founding engineer of five 0→1 products — Euda, Rovik, Brightkind, Budget Wise and Agent Studio. The leverage that makes this possible is agentic engineering, which I research and write up in the open.

I mentor entrepreneurs, engineers and engineering leaders going deep on agentic engineering and agent architecture — helping them turn new patterns, tools and operating models into practical engineering capability.

Here I share what I'm building and learning. If you're in the trenches on agentic engineering, agent architecture, or flow, reach out.

🌶️ “Spec-driven development + autonomous agents” is just Waterfall 2.0.

Yes, I'll keep banging on it. We saw the news that Cursor ran long-running coding agents for close to a week on a single project and ended up with a browser rendering engine from scratch (HTML parser, CSS cascade, layout/rendering, etc.
