I am Yang Qing, a full-stack software engineer with extensive experience delivering SaaS, banking, marketing, and healthcare solutions. I work across Java, Node.js, Python, and modern frontend frameworks (React, Vue) while applying cloud, DevOps, and AI/ML techniques to build scalable, multi-tenant systems. My focus includes cross-border payroll/EOR platforms, AI-driven marketing content, and hospital information systems, with a strong track record of turning complex requirements into robust architectures. I hold AWS DevOps Engineer Professional and AWS Solutions Architect Professional certifications and have hands-on experience with Kubernetes, Docker, CI/CD, and AWS services. I enjoy collaborating in Agile teams, mentoring teammates, and contributing to hospital tech and patient-insurance domains. I’m motivated by solving hard problems, from distributed systems to Web3 apps and AI-enabled workflows, and I value clear communication and measurable outcomes.…I am Yang Qing, a full-stack software engineer with extensive experience delivering SaaS, banking, marketing, and healthcare solutions.
