Experience

Aria Language

https://github.com/renan061/aria

A programming language built with safe concurrency and parallelism in mind. Aria uses built-in monitors as the only way to share mutable data between threads. The implementation uses standard tools and libraries, such as Lex (Flex), Yacc (Bison), LLVM (LLVM-C API), and POSIX threads.

Globoplay

https://globoplay.globo.com

An iOS app that streams content from TV Globo to millions of users. Globo is a major television network in Brazil. I maintained the application and added functionalities in collaboration with a team of up to five developers.

Elo Language

https://github.com/renan061/elo-coq

A programming language project written in Coq, OCaml, and Haskell. Elo is the byproduct of my PhD research thesis involving safety in concurrent programming languages and formal proofs. It uses Coq to define a language's semantics and type system and prove that Elo does not allow data races to occur.
