- 2022 - present: Sapienz
I am working on integrating Sapienz -- an automated UI testing engine -- with WhatsApp iOS client to perform taint analysis of privacy properties. - 2021 - present: Infer
Infer is a general purpose static analysis platform developed at Meta. I am working on the Erlang frontend, a callgraph reachability analysis and the integrations with WhatsApp server and client codebases. - 2021 - 2022: FAUSTA
FAUSTA is an automated testing for WhatsApp server with traffic generation. I worked on more precise fault localization. - 2015 - 2021: Theta
Theta is a generic, modular and configurable model checking framework. I was one of the original founders and main developers, focusing on the abstraction-based algorithms for transition systems and programs.
