Rockstar🎓
Top SchoolThibaut Courouble is a principal developer and co-founder with 15 years of experience building large-scale web platforms, APIs, and resilient developer ecosystems. Based in Ottawa, he has led architecture and product teams at Shopify—shaping the Online Store, Theme Editor, and Liquid language—and later returned to hands-on engineering at Patch before co-heading Jane.ai. He blends deep Ruby on Rails and frontend expertise (JavaScript/TypeScript, HTML/CSS) with pragmatic system design around databases, caching, performance and long-term maintainability. An entrepreneurial builder, he created DevDocs.io—an offline-first API documentation browser used by hundreds of thousands—and has contributed performance improvements to widely used open-source projects like Shopify's identity_cache. Known for mentoring engineers across levels and hiring and growing teams from scratch, he favours simplicity and durable solutions that scale. He’s comfortable moving between product, design and ops to ship extensible UIs and platforms that endure.
