Top SchoolFrancis Hamel is a Lead Software Developer with nine years of experience building resilient backend systems and driving operational improvements across payments and observability platforms. He has led architecture and delivery efforts at Shopify—instrumenting internal tooling, migrating observability stacks, and building a Presto-powered engineering metrics pipeline—and later reduced cloud costs and introduced CI/CD and feature flags as a Senior Full Stack Developer at TaliPay. Now leading development at clicknpark, he blends hands-on implementation with mentoring and documentation to scale teams and systems. A Université de Sherbrooke computer science co-op alumnus based in Montreal, he’s comfortable across the stack and often focuses on pragmatic system observability and secure certificate management—work that quietly prevents downtime at scale.
