About Me

I'm a senior collaboration engineer with over 20 years in enterprise IT, the last 13 focused deeply on Cisco Unified Communications. I've designed, deployed, and maintained UC environments ranging from small single-site offices to large multi-site enterprises with thousands of users, including full-stack voice infrastructure, contact centers, and video collaboration.

My approach combines hands-on technical delivery with a strong automation mindset. I write custom Python tooling to streamline provisioning, migration, and operational tasks — from AXL/REST API integrations to full provisioning automation with Webex Calling. I've authored UCCX scripts, built data migration pipelines, and created open-source SDKs for the Cisco platform.

Most recently, I've been expanding into AI-driven automation and infrastructure tooling, building intelligent monitoring systems, automated workflows, and exploring how LLM-based tools can augment engineering operations.

I'm looking for a senior or staff-level role where I can combine my deep UC expertise with my growing automation and AI skills — ideally remote-first, with a team that values engineering craft and practical innovation.
