Rockstar🎓
Top SchoolRyan Balsdon is a versatile software developer with 12 years of cross-domain experience spanning embedded hardware, PCB layout, mobile and web apps, site reliability, and data engineering. He built and maintained the infrastructure that powered Shopify’s retail payments, driving checkout and payments reliability improvements by orders of magnitude and completing EMV Level 3 certifications and HSM integrations. Comfortable in ambiguous, chaotic environments, Ryan has shipped production-grade backend systems, secure CI/CD pipelines, and cloud-native deployments on GKE while leading payment, invoicing, and reporting upgrades. He combines low-level hardware insight with high-level service reliability, having designed payment hardware and authored payment libraries integrated into PCI-compliant systems. Based in Ottawa, he’s known for pragmatic problem solving and for translating complex compliance and security constraints into reliable, auditable systems. Outside core deliverables he’s also fostered engineering culture—running an internal podcast and teaching hundreds in a maker space—demonstrating an appetite for mentorship and clear communication.
