Senior🎓
Top SchoolDaniel Ryan is a versatile software engineer with 11 years of experience building full-stack, mobile, and cloud-native products from startup to enterprise scale. Based in Barcelona, he has shipped secure, production systems—ranging from AWS/Terraform-deployed financial platforms and serverless lending backends to multilingual e-commerce sites and Expo-powered mobile apps. He often works as the sole or lead engineer, owning architecture, CI/CD, and multi-role access controls for complex domains like sober living management (6,500+ residents) and AI-driven credit scoring in emerging markets. Comfortable across JS/React/Next.js, React Native, Python, and AWS, he pairs front-end polish and data visualization with backend automation and infrastructure-as-code. Notably, he’s built SDKs and automation that prevent billing errors, implemented multi-environment Terraform deployments, and migrated legacy mobile stacks to faster Expo workflows to improve release velocity. Practical, detail-oriented, and hands-on, he thrives on turning operational problems into maintainable software.
