Summary
🤩
RockstarEwerton Da Silva is a Senior Software Engineer with a decade of experience building and hardening IoT SDKs and tooling for Microsoft Azure, based in Seattle. He specializes in backend systems, TLS/SSL reliability, transport protocols (AMQP), and cross-language SDK maintenance across C, Java, C#, and Node.js. At Microsoft Azure IoT he has driven production fixes—memory-leak patches, reconnection and C2D message handling, and build-system updates—that surfaced across high-impact repos like azure-iot-sdk-c and azure-c-shared-utility. Comfortable across low-level C networking and higher-level SDK design, he also contributes to packaging and automation (vcpkg, build scripts) to smooth release workflows. Colleagues rely on him for pragmatic bug-forcing and interoperability work that keeps device-cloud communication robust at scale. Notably, his contributions reveal a focus on reliability and testable client behavior rather than just feature development.
