Summary
👤
Senior🎓
Top SchoolRenato Costallat is an embedded software developer with 11 years of experience building resilient test labs, automating DevOps workflows, and developing C/C++ VoIP and embedded systems. Based in São Paulo, he has driven large migrations from VirtualBox to QEMU, introduced Docker-based build and test environments, and implemented Jenkins pipelines, Zabbix monitoring and LDAP-backed toolchains to stabilize fragile development infrastructure. He combines low-level protocol work (SIP, MGCP, H.248, OSPF, RSVP) with practical automation—writing Python tools to provision switch ports, manage test-bed locks, and speed manual test flows. An active contributor to the OTServBR project, he improved server logic and added Docker-powered local test environments, showing a taste for both game backend fixes and infrastructure hardening. Known for thorough documentation and lab diagrams, Renato blends hands-on embedded development with DevOps rigor and a continuous-learning mindset in areas like cloud, IA and Kubernetes.
