What I'm looking for

I'm looking for environments with clear goals, high trust, and autonomy to make meaningful technical decisions, turn ambiguous problems into reliable software, and contribute to product direction.

I've built and shipped production software end-to-end since 2021, including DOT Permit Routing, AskUpstream, Estate Map, and GAP Smart Inventory. My work combines product framing, architecture, implementation, testing, deployment, and production maintenance.

I use AI agents, LLM integrations, RAG, APIs, and automation to accelerate delivery while keeping critical decisions grounded in deterministic code, validation rules, and human review. For GAP Smart Inventory, I reduced stock loss by 60% and inventory-management administrative time by 80%.

Before independent product engineering, I spent nearly a decade at Cisco supporting critical enterprise customers and complex Collaboration and Data Center environments. I work best with clear goals, high trust, autonomy, and room to contribute to product direction.
