## About

```text
I'm building and maintaining C/C++ embedded Linux software for carrier-grade optical networking devices at Zhone, spanning hardware interfaces, system services, and application components.

I've delivered end-to-end functionality from UART and I²C hardware control through RESTCONF APIs and React/TypeScript web interfaces. My work includes thermal management for TEC hardware operating down to -40°C, EEPROM access, sensor integration, and register-level programming.

Previously on the Zhone Technologies project at Encora, I developed, reviewed, and refactored production C/C++ libraries for embedded Linux optical networking systems. I added support for hardware devices and optical pluggables while maintaining capability mappings, protocols, hardware configurations, and low-power functionality.

I work across multithreaded systems, networking, debugging, build integration, and automation, using Python and shell scripts to support development and testing. I've also integrated AI-assisted code-review workflows with GitLab and Bitbucket for international Agile engineering teams.
