Principal Research Software Development Engineer at Microsoft
Redmond, Washington, United States
Summary
🤩
Rockstar🎓
Top SchoolTahina Ramananandro is a Principal Research Software Development Engineer at Microsoft Research with a decade of experience building and verifying critical software systems using functional languages and proof assistants. Her work spans the Everest project, EverParse, and F*, applying mechanized proofs to networking, parsing/serialization, and cryptographic libraries—she’s contributed to high-profile projects like HACL* and FStarLang. Trained with a PhD in Computer Science and a strong background from Inria and Yale, she combines deep formal-methods expertise with practical engineering, resolving complex merge conflicts, CI build issues, and low-level buffer/module refactors. Colleagues rely on her to bridge theorem proving and production tooling, delivering auditable, secure implementations rather than prototypes. Her uncommon blend of formal verification, compiler/OS verification experience, and hands-on backend/security contributions makes her a go-to engineer for trustworthy systems.
