# Harness Engineering: Lessons learned

**When AI agents write most of your code**, you'd think the job gets easier. It does, and it doesn't. You spend less time implementing and more time setting up your repo, docs, and review gates so the agents don't produce garbage. OpenAI recently called this **"harness engineering"**. Nico (co-founder of Velario) and Denis (AI Engineer) will talk about what this looks like day-to-day with Claude Code: how small teams actually ship this way, which workflows hold up, and what falls apart.
What's changed in **how startups ship, **what **tools and workflows** actually work in practice, what **challenges** come with building this fast
**About the Speakers:** **Nico** is co-founder of **Velario**, building products at the frontier of AI-assisted development. **Denis** is an **AI Engineer**with hands-on experience shipping fast with modern AI tooling. Together they bring real, practical insights from the trenches of building in 2026.
