Rockstar🎓
Top SchoolLuis Azedo is a distributed software engineer based in Portugal with 13 years of experience building scalable back-end systems, particularly in telecom and VoIP domains. At 2600hz he works on core distributed telephony infrastructure and has contributed significant fixes and features to high-profile open-source projects like FreeSWITCH and Kamailio. His hands-on Erlang work on projects such as erlcloud and kazoo shows deep expertise in messaging, SIP call management, AWS integrations, and reliable distributed patterns. He pairs operator-minded engineering with product focus—having managed teams and run a company—so he balances code-level contributions with delivery and operational concerns. Notably, his contributions include nuanced SIP call interception logic and AMQP enhancements, demonstrating comfort with low-level protocol details and large-scale messaging systems. Fluent in pragmatic maintenance and feature work, he often improves observability and API behavior while keeping systems robust in production.

Back-end DeveloperContributions:4 reviews, 109 commits, 43 PRs in 5 years 6 months
Contributions summary:Luis primarily contributed to the `signalwire/freeswitch` repository, focusing on enhancements related to handling SIP messages and call management. The user modified code within the `mod_sofia` module to conditionally intercept replaced call IDs and handle the "replaces" header for call interception. The user's work appears to be solving issues regarding call picking and intercepting specific call legs, likely related to the voice-over-IP and telephony aspects of the project. The commits also included improvements to SMS delivery reports and integrations with the mod_kazoo module.
