I also created an automated BDD test environment for a legacy system, eliminating about four hours of setup and reducing the full test suite to three minutes. Refactoring the DNS filter cut per-request latency by 5x and added IPv4/IPv6 support. At Atlântico, I adapted an embedded Linux platform to support WiFi-enabled devices and developed C++ modules for NetworkManager and remote diagnostics. I also redesigned the IPC layer with a thread-safe C++ library. Earlier, I developed Python analytics tools for performance testing and C/C++ firmware for WiFi/LoRa mesh networks. My work has also included embedded systems research and investigating a battery issue that helped avoid a product recall. ``` ## Experience ### Senior C++ Software Engineer (current) Datum.
