Professional Profile

Hands-on Principal Software Engineer who owns high-availability cloud platforms, enterprise data infrastructure, and multi-system integrations at scale—including a $27M BigCommerce commerce platform and an AWS data warehouse (Glue, Athena, S3, RDS). Builds full-stack product features end-to-end, from React and Vue.js front ends to Node.js/Python services and the underlying data layer. Internal solutions architect for Salesforce, NetSuite, Piano, Cvent, and related pipelines. Applies LLMs and orchestration tools to accelerate delivery and add AI capabilities to products and pipelines, with the same reliability, cost, and compliance discipline used across PCI, MilSec-, and privacy-regulated systems. Mentors engineers and sets standards across cross-functional teams.

In short, I solve hard business problems with technology, and I ship on time.
