​What actually happens when your AI agent meets production traffic?

​Most agent demos work.

​Then they ship, and the edge cases show up: tools that fail, context that drifts, or a retry loop that quietly burns your budget.

​Harness engineering is the discipline that closes that gap - the guardrails, tests, and structure that keep an agent behaving once it's out of your hands.

​For this workshop at Ethereum Hub, we'll welcome Gabriel Novak, co-founder and CRO at Shippit, who's been deep in DeFi and AI + blockchain systems and mentors founders on turning Claude Code from a commodity into a repeatable engineering system.

​He'll lead the session together with Julia Hoffmann, Head of Product at Rivool Finance, who's spent the last few years at the intersection of product, design, and engineering - co-founding Chainless at Notus Labs, building jubs.studio, and shipping AI-native and Web3 products end to end, from interface to code.

​Prepping for the EAG Global Buildathon or want to put your skills to the test for a shot at 30 days in China?

​This workshop doubles as prep for that too - make sure you're registered here.

​🛠️ Harness Engineering Workshop

​This is not a generic AI hype talk or a deck of prompting tricks.

​It's a hands-on look at the practices that keep an AI agent from breaking once it leaves the demo and meets real production traffic - testing, guardrails, and the engineering habits that turn a clever prototype into a system you can trust.

​🗓️ How it works

​6:00 PM - We gather at the Hub
7:00 PM - Harness Engineering Workshop with Gabriel Novak and Julia Hoffmann
Afterwards - Networking

​You're also welcome to spend the day working from Ethereum Hub before the event. Bring your laptop, work from the space, and stay for the conversation.

​💚 Who should come?

​This is for people building or shipping AI agents - engineers, founders, and builders who want their agents to survive contact with production, not just look good in a demo.

​You don't need to come with all the answers. Just come curious.
