Rockstar🎓
Top SchoolJustin Giancola is a senior software engineer with 17 years of experience focused on stabilizing and simplifying complex, high-risk systems so they become more capable and maintainable. He has led engineering work across startups and scale-ups—building a payments backbone and one of the world’s largest digital coaching platforms at Precision Nutrition, founding the core AI-driven food estimation system at Alma, and now driving engineering at Modem. Justin blends front-end craftsmanship (notably contributions to the Ember.js framework) with backend reliability, distributed billing, and multi-model AI orchestration for real-time, multimodal inference. He favors the parts of systems others avoid and excels at turning ambiguity into auditable, production-ready processes. Based in Old Toronto with an Hon. BSc in Mathematics from the University of Toronto, he pairs rigorous analytical thinking with pragmatic engineering. A detail that often surprises colleagues: he routinely balances deep technical design with hands-on testing and evaluation frameworks to keep fast-moving AI systems both accurate and performant.
