  [Casbin Mentor]
  [\iconlink[\faGithub][Casbin-Mesh/neo]{https://github.com/casbin-mesh/neo}] % TODO: github link
  \begin{itemize}
    \item Leads the development of \textbf{Casbin Neo}(new engine option), a Casbin-compatible engine. \iconlink[\faGithub]{https://github.com/casbin-mesh/neo}
    \item Introduces the Synchronization Adaptive Radix Tree, 2-4x faster than BadgerDB's lock-free version Skip List, and 4-6x faster than Std Sync Map.  \iconlink[\faGithub]{https://github.com/casbin-mesh/neo/issues/10}
    \item Builds the all new expression evaluation system, 2-8x faster than the origin dependency.  \iconlink[\faGithub]{https://github.com/casbin-mesh/neo/pull/54}
    \item Introduces the MVVC(Multi-Version Timestamp Ordering) Index  \iconlink[\faGithub]{https://github.com/casbin-mesh/neo/pull/38}
