👋 Hi, I’m @EasonXeu
I’m a software engineer with 8 years of hands-on experience, having worked at top tech companies including Alibaba Cloud and Huawei. My core expertise lies in building high-performance, scalable, and secure systems, especially in the field of cloud infrastructure and security.
At Alibaba Cloud, I led and contributed to the design and development of several key authentication systems:
- AccessKey – A mission-critical, high-availability authentication system that sustained 3B+ QPS and served as the security backbone of the whole cloud platform.
- Login Center – Provided centralized login management to all IAM users.
- CloudSSO - Provided big companies with seamless SSO experiences across their multiple cloud account.
These projects gave me deep experience in distributed architecture, fault tolerance, and high-availability design, ensuring 99.99% uptime under extreme workloads.
I have deep insights and hands-on experience with security protocols, algorithms, and risk control systems, including:
- Authentication & Authorization: IAM, OAuth 2.0, OIDC, SAML 2.0, SSO, MFA, FIDO/WebAuthn
- Cloud Security Components: AccessKey, STS, KMS, Risk Control, Device Fingerprint
- Zero Trust Architecture: Secure Identity Flows & Adaptive Authentication
In my spare time, I actively share technical insights through blogs, courses, and open-source projects:
- 🎓 Creator of a Java Web Development Masterclass with 8,000+ paid attendees
- ✍️ Technical blogs on:
