Justin Marsh

Lead Software Engineer

Gaia Law

I'm Justin, a Berlin-based full stack developer with 6+ years of experience building web applications for startups and consultancies. I'm currently the lead developer at Gaia Law, where I'm building AI-powered tools for contract management and equity management.

I'm product-focused and design-oriented — I believe beautiful code and thoughtful interfaces go hand in hand. I favor domain-driven development and care deeply about crafting software that solves real problems elegantly. My stack centers on Ruby on Rails, React, and modern JavaScript frameworks.

Beyond my day job, I've built passion projects like tangotube.tv and tangocloud.app — media platforms for the Argentine Tango community. When I'm not coding, you'll find me on the dance floor.
