Summary
👤
Senior🎓
Top SchoolHasini Witharana is a scientist and security-focused software engineer with 10 years of experience blending SoC verification, pre-silicon security research, and backend identity engineering. Currently at Intel and finishing a PhD at the University of Florida, she has driven scalable frameworks for verifying SoC vulnerabilities and worked on Trusted Execution Environment security and CPU side-channel mitigations. Her strong systems and hardware-software co-design skills are complemented by practical backend contributions to well-known open-source identity projects at WSO2, where she fixed critical OAuth/OIDC bugs and hardened authentication and configuration handling. Comfortable in C/C++/Java/Python and Verilog, she bridges research rigor with production-grade engineering, often translating academic security assertions into deployable verification tooling. An interesting thread through her career is repeated work at the intersection of identity, trusted execution, and platform security—bringing both protocol-level expertise and low-level hardware insight to complex system defenses.

Role in this project:Back-end Developer
Back-end DeveloperContributions:43 commits, 28 PRs, 100 comments in 2 years 4 months
Contributions summary:Hasini primarily focused on fixing issues related to the OAuth 2.0 and OpenID Connect (OIDC) implementation within the WSO2 identity server extensions. Their contributions addressed critical bugs, including incorrect handling of the 'Bearer' header in user info endpoint requests, caching issues in the userinfo endpoint, and incorrect formatting of the address claim in OIDC responses. Additionally, they introduced a new configuration property to control the pool size for OAuth persistence tasks.
