Rockstar🎓
Top SchoolJosemar Luedke is a software architect and engineering leader with 15 years of experience designing and shipping full‑stack web platforms, now based in San Francisco. He has led architecture and delivery for multi-tenant, containerized systems and fiber broadband demand platforms, blending Ember.js frontends with GraphQL and Go backends. A long-time contributor to the Ember ecosystem, he’s helped modernize templating and build tooling in high-profile projects like ember.js and Embroider.

Comfortable across the stack, he also has deep roots in Ruby on Rails and payment integrations from his open-source crowdfunding work. Outside of technical leadership, he’s a coffee-loving pragmatic engineer who favors practical refactors that reduce tech debt while enabling new product capabilities.
