Summary

Rockstar🎓
Top SchoolFelipe Pena is a Senior Software Developer and Tech Lead based in Rio de Janeiro with 18 years of experience building backend systems, data engineering pipelines, and compilers across C, C++, C#, V, PHP and Python ecosystems. He blends hands-on systems work—Linux administration, ETL, cloud orchestration (GCP/AWS/Azure) and CI/CD—with deep security and reverse-engineering expertise earned through historical CVE discoveries and active fuzzing/CTF work. A long-time open-source contributor and core PHP/V language developer, he has fixed critical bugs in projects like php.net, Parrot VM and the V compiler and co-created native tools such as phpdbg and coverage/debug tooling for V. Felipe is equally comfortable optimizing databases and distributed services as he is digging into compiler codegen or eliminating memory leaks, and he often bridges integration gaps using middleware (JBoss Fuse) and orchestration tools (Airflow, ADF). Notably, his contributions include practical improvements to widely used projects (php.net, V, v8js) that reflect a knack for stabilizing complex C-level systems while shipping new language features.
