  Rio de Janeiro, RJ, Brazil
  Scholarship; Researcher
  Development in Lua and C, working on projects in cooperation with various PUC-Rio laboratories:
  ◦ LAC - Laboratory for Advanced Collaboration - ported a communications protocol implementing a reliable transport layer on top of UDP from Java to Lua, including a coroutine scheduler emulating Java threading construct semantics, and a pure-Lua implementation of Java’s native object serialization protocol.
  ◦ GIGA - Grupo de Inovação e Gestão Ambiental - a project of a scripting layer for an embedded system based on an RTOS to be used in the transportation industry, including both coroutine-based and promises-based non-blocking APIs.
  ◦ Instituto Tecgraf - reimplemented a C-based monitoring daemon into pure-Lua and replaced the CORBA communication layer between the daemon and a Java server with a RESTful API, embedding an HTTP server in the Java server and writing a compatibility bridge with its internal legacy APIs.
