Dylan Ryan

I’m a Senior Full Stack Software Engineer with 10+ years of experience designing and delivering scalable cloud-native applications across fintech, advertising, healthcare, and SaaS. I focus on end-to-end delivery of distributed systems, secure authentication platforms, and large-scale data processing.

At Mastercard, I led the design and implementation of enterprise authentication and authorization for a multi-tenant BI platform serving over 1,000 global customers, integrating a SAML identity provider with custom role-based access control. I also built customer-facing analytics functionality with .NET and React, contributing from data modelling through production deployment.

I’ve driven technical leadership across system design and operational excellence, including CI/CD pipelines for a Java and React monorepo using Jenkins, plus root-cause analysis to improve reliability and release success. I’ve supported architecture decisions, sprint planning, code reviews, and mentoring junior engineers across multiple initiatives.

Previously at Amazon and Sintel, I led large-scale platform and compliance work—such as designing a datastore for Amazon Advertising Benchmarking and building SOX compliance reporting pipelines with Scala, Spark, and SQL. I bring deep backend and frontend expertise in .NET, Java, Node.js, Python, React, TypeScript, and cloud infrastructure on AWS and Kubernetes.
